Comments on: Palm OS 5 Will Be Up to Three Times Faster Than OS 4

When PalmSource decided to make the change from Dragonball processors to ARM-based ones, it was important to keep backwards compatibility to the thousands of existing applications written for the Dragonball processor. There has been a certain amount of nervousness that this process would make these applications run slower than they do now. According to Mike Mace, PalmSource's Chief Competitive Officer, nothing could be further from the truth. In an interview with the pdabuyersguide, he said "In preliminary testing, Palm OS applications are running up to about three times faster on Palm OS 5 than they do on the current systems."

Once upon a time, in the not too distant future...

"Well, we thought OS 5 was up to three times faster than OS 4, but in reality it is three times slower due to the OS 4 simulator. It was an honest mistake. We really believed it was going to be three times faster. We apologize for any convenience we may have caused."

I'm patiently waiting for my OS 5 device myself but I'm more than a little curious what is taking so long. It isn't like Palm and Sony didn't know it was coming.

If Palm wasted a lot of time on OSLO and decided to drop it, that might explain why they are a bit behind schedule. But I expected Sony to have something out within a month of PalmSource finishing OS 5. Don't they realize the first one out of the gate will have a huge advantage?

On the other hand, I'd rather they take their time and do it right rather than just dumping something half baked on the market.

I say the same thing . . Palm is so predictably lame nowadays. I wouldnt jump to PPC, but I can sure tell you that my brand loyalty and perceived value of ALL handhelds is DRASTICALLY lower than it was a year ago. Palm will overprice these models and struggle some more . . .

Speaking of releasing new hardware without getting your ducks in a row, we have the Pocket PC platform as a prime example. At least I know the 400 MHz Palm OS models will run faster than the 200 Mhz ones!! Compaq didn't get nearly as much *** for that as they deserved.

It is looking like Oslo has turned out to be nothing but a proof of concept to get Sony, Acer, and the like to create hardware for PSource. Hey Palm too much hype for too long and not enough action! Im stopping the insanity and moving over to PPC because the PPC software has finally caught up to Palm as far as basic PIM apps are concerned.

How many future customers is Palm going to piss off before it steps up to the plate and says ok here is version 1 of the new Palm and it will be released on this date.

I honestly think the message board has become the silliest freak show lately. Palm Source HAS ALREADY DELIVERED THE GOODS - so stop dissing them. Palm Inc on the other hand - thats a different matter. Even so - they have only had the final release for a couple of months (and the beta for another few). Do want them to rush your fantasy device out the door only to have some stupid hardware glitch? The stakes are high (what with stupidity like the m130 screen debacle) and the pressure is on - they have to make damn sure they don't mess this up - the companies future is riding on the next wave of os 5 devices.

As for people whose lives revolve around checking this site every day and fereaking out like little children about how you 'just can't wait anymore' and now your jumping ship to PPC: fine - do it already and go post at PPCThoughts or something.

Predicted Release Schedule

Token User @ 8/26/2002 2:33:49 PM #
Just speculation but ...

September -
Rumours : Rumours of an announcement date for new models from Sony and Palm in October.
Sony : Announce another new unit. Retire two others.
Palm : Acknowledge that new units will be released before the end of the year.
General : Back to school specials and college bundles.
Everyone else : Same old thing.

October -
Rumours : Leaked pictures for devies being announce in November appear on the net. Much speculation on the specs.
Sony : Announce another accessory that unfortunately wont fit a majority of PDAs their users are carrying.
Palm : Deny that the photos are for a model that is being released, but confirm that an announcement will be made soon. Real soon.
Everyone else : Same old thing.

November -
Comdex rolls around.
Sony : have already released their current suite of models and have them available for purchase.
Palm : Demos 5 new models - 1 high end PalmOS 5 device running on a XScale CPU that looks surprisingly like the Oslo they denied so heavily, 1 low end colour OS4 device running on a 66MHz DragnonBall (m115), 1 pda /w cell phones capability via a headset, 1 cell phone /w pda capability (stripped down PalmOS version, small colour screen), and 1 PDA/GPS hybrid by Garmin.
Handspring : New CDMA based Treo announced (where did that come from? No rumours??). Includes SD slot, builtin bluettoth, and Qualcomms gpsOne chip. Also runs BREW binaries. Could be the killer device. Also announce version for GSM/GPRS early 1Q03.
Handera : PalmOS 5.0 PDA. Its screen is big enough to be a tablet. Largest colour screen on market in a PDA (unfortunately to use it fully requires custom API's), builtin 802.11b, CF and SD. Microdrive and external power supply options. Cheaper than a laptop. Lighter than a PocketPC tablet. Becomes popular in educational markets. Comes with enhance WP, SS, DB, and email software.

December -
Sony : Devices on the shelves in Best Buy, Circuit City, Sears, and 7-11's across USA.
Palm : Production delays - but you can pre-order for delivery in time for Xmas (or maybe the New Year) on their web site.
Handspring : New model available at Verizon in the US, and also in Korea and Japan (Japanese version is bright pink with "Hello Kitty" logo).
Handera : Avialable online, through Sam's Club, and in college book stores.

Just postulating.

Anyone want to predict the ratio of OS4 to OS5 devices that will be sold?

Could not have said it better myself.

I think the PDA market will get the biggest shock of their lives (go down in history) if Palm was to deliver on time.

Even knowing this, people still get pissed off. We all know that the new Palm device is NOT just around the corner, there will a multitude of OS5 devices by other manufacturers before Palm will be able to actually get their devices on the shelves. And of course the true loyal fans (as myself) go and buy one on pre order, and guess what? 3 months later an update with more memory, brighter etc, same price, same predicament as the m505 buyers(as myself), just not worth the upgrade, another $1000 Aus. Once again loyal customer get burnt.

Palm better hope to hell that Sony never put an SD slot on their devices, otherwise bye bye.

''Advanced multimedia features...

Palm might add some multimedia features but you KNOW Sony will. Entertainment is right there in the CLIE name.

I hope everyone doesn't emphasize multimedia at the expense of size and battery life, as all PPC devices and some Sony ones do. I don't want to watch movies on my handheld, I don't even do that on my laptop. I have a TV. I want the faster speed but I also want something not too much bigger than a Palm V.

RE: ''Advanced multimedia features...
I.M. Anonymous @ 8/26/2002 11:53:58 PM #
Sony has already done that. Look at the battery life on everything beyond the T615. Most notably the T665c. I can understand the battery life in the NR series because of the bigger screen. But the T665c is awful, because of all the lovely multimedia features.

It's a shame they couldn't keep up the battery life of the N760c.

Ah well.
I assume battery life will continue to dwindle.

3x faster is good but I can't wait for OS 6. Remember this from February?

> code that has been recompiled for ARM-based chips is 61 times faster
> on a 200MHz ARM processor compared to a 33MHz Dragonball one

It is great that we won't have to wait for new apps to get a speed boost with OS 5 but once OS 6 and fully ARM native apps are out, we're gonna be smokin'!

RE: Just the Beginning
I.M. Anonymous @ 8/26/2002 6:18:27 PM #
Yup, and that's still true for OS 5, potentially. In the interview they are talking about existing 68k applications runnings under emulation (ie no code change at all) - developers can write ARM native code for portions of their app that needs a real speed boost - this is where you'll see the orders of magnitude speed increases.

Nothing new here. Mace doesn't get the ARM/StrongARM/X-Scale/TI OMAP issues at all. He didn't come close to answering the StrongARM/X-Scale issue with and answer not dreamed up by his marketing department.

Meanwhile, no new devices. No multitasking. No standard multimedia API. No custom fonts. No bloody file system. But hey! I can use any one of the 350+ calculators that comprise that 14,000 total apps.

On the apps, how is it they have over 200,000 developers and only 14,000 apps? Are we to believe that each app is taking about 14 people to develop it or is their developer count so blown out of whack because they are tracking how many hits on the dev kit download page?

StrongARM vs. XScale
Ed @ 8/26/2002 4:06:25 PM #
One thing Mike didn't make properly clear was that no Palm OS 5 devices will use StrongARM processors at all. The StrongARM family isn't part of the Palm OS Ready Program. Any Palm OS handhelds running Intel chips will be using XScale ones.

If you are concerned the Palm OS will have the same problems Pocket PC 2002 has with XScale processors, you need to read this article:

"On the apps, how is it they have over 200,000 developers and only 14,000 apps?"


At least 1/2 of these are just wanting to run POSE with different roms.

Then cut it in half again to cover those who are just playing around with the tools.

Then double the number of apps to take into account that many of them are
custom in-house only apps.

This gives roughly a 2:1 ratio between developers and apps.

Palm to take full advantage? You base that on this?
"Gina Clark, VP of Marketing for PalmSource, said when the PXA250 was announced, "Intel's high-performing, low-power processors coupled with the Palm OS, make for a compelling and powerful platform. Palm OS licensees and the broad base of Palm developers will be able to take advantage of the full benefits of the Intel XScale technology." "

Uh huh. Right after they get their color combinations jiberish resolved, we'll see if it takes "full advantage."

How can you take full advantage of a 32bit processor that addresses well over 256MB of RAM with an OS that doesn't allow you to multitask, much less multithread?

RE: So lame....
useybird @ 8/26/2002 10:52:03 PM #
the only reason most of those apps are lame is because palms don't have all the capabilities yet. As soon as an OS5 device comes out there will be alot more apps available to take advantage of its enhanced hardware i.e. Wi-Fi, Bluetooth, Voice recorder, hires screen, enhanced speaker, etc.

Guy - you should know what yr talking about before posting - it saves embarassment. Speaking of embarassment, PDABuyersguide got it wrong when they asked him the question:
"With Palm OS 5 coming out running on the more powerful StrongARM processor, what would you say Palm's competitive edge will be?"
I think the interviewer over there should be fired for not knowing his facts (it is a site about PDAs afterall) but thats just my harsh opinion. Why? NEWSFLASH: Palm or PalmSource HAVE NEVER SAID that OS5 runs on StrongARM - EVER. I don't why this is so confusing but it goes to show how badly researched a lot of reporting/media is (except PIC - the best site for trying to get to the bottom of this confusion). Even WIRED said this in different articles - all perpetuating this notion that 'Palm is just getting to StrongARM, while PPC is moving on to the next generation'. In fact the opposite is true: Unlike the neandrathals at M$, Palm came up with the idea of HAL (hardware abstraction layer) - which each CPU manufacture writes to optimize there particular variety of ARM chip (XScale is ARM btw) for the OS. M$ shortsitedly hardcoded optimization for 1 chip - StrongARM - into the OS. Thus the whole XScale problem we've been hearing about in the PPC camp.

Anyway - just wanted to reclarify that and point out that Michael Mace was 100% correct and that PDABuyersguide got there facts completely wrong. The only problem with Michael Mace's response was not pointing out that the interviewers question was factually incorrect.

MS uses a HAL too. the PPC isn't hardcoded to the StrongARM, it is coded to ARM. The new HP 928 WDA Pocket PC 2002 Phone selling in Europe runs on a TI OMAP *ARM* processor, not StrongARM. The X-Scale issue is an optimization issue, like moving from a PIII to a PIV. Remember that until Intel fixed some the the PIII emulation issues how many PIII's would blow the doors off of a PIV? No, of course you don't. You were too busy reading the Zen paperwork.

OS5 faster assuming same MHz?

I.M. Anonymous @ 8/26/2002 5:19:25 PM #
Is OS5 faster because the OS is better optimized or because ARM's can run more efficiently? Or is he saying it'll be 3 times faster on a 200MHz ARM than on a 66MHz Dragonball?
RE: OS5 faster assuming same MHz?
I.M. Anonymous @ 8/26/2002 7:45:01 PM #
Yes it is.

Dragonball is based on 68000, CISC-type processor which require multiple clock to run single instruction. ARM, is RISC by name, required only one clock to run one instruction. At the same clock speed, supposely, ARM should run faster than Dragonball.

Newer version of ARM could run multiple instruction in single clock. So, it should be way faster than Dragonball. Same as PowerPC 1GHz perform better than Pentium 2GHz.

RE: OS5 faster assuming same MHz?
hotpaw4 @ 8/26/2002 8:09:29 PM #
3 times faster than what I wonder (since PalmOS handheld CPUs span the range from 16 MHz to 66 MHz)?

OS5 runs on ARM RISC CPUs, which, at the same clock rate, should execute native ARM instructions 4 to 15 time faster than a 68000 can execute its instructions, depending on things such as the CPU pipeline implementation, instruction mix, memory wait states, cache bandwidth and cache hit ratio. An unoptimized PACE emulator appeared to execute 68k code around 10 time slower than a "real"* 68000 running at the same clock rate. The CPUs that PalmSource is certifying for OS5 seem to have clock rates 2 to 3 time higher than a 66 MHz 68k Dragonball. There are lots of variables. But is easily possibly for a native ARM benchmark to run over 100 times faster on a 200 MHz OS5 system than the equivalent program on Palm III; and it's possible for a game application that uses its own hand coded 68k assembly language routines instead of the OS routines for graphics to actually run slower on a low-end OS5 system than on an NR70. It really depends on the percentage of time an app spends calling OS routines which will run in native ARM code in OS5 devices, thus very much faster, and the time it spend in its own 68k code, thus much slower. So I'll bet that 3x is just the mean of a very wide spread from 0.5x to 100x.

* A "real" MC68C000 doesn't actually execute 68k instructions directly; it used 2 levels of microcode to interpret the 68k ISA on it the physical hardware.

RE: OS5 faster assuming same MHz?
I.M. Anonymous @ 8/27/2002 8:30:43 AM #
The last poster has hit it on the head. I have tested on a variety of PalmOS5 hardware so far and have found the following

An App doing no OS calls, running totally in emulation runs about 3X faster (200Mhz CPU). An app doing normal OS stuff (Drawing forms, accessing databases) 10X-20X faster depending on what you are doing. An app written compile for ARM native up to 60X.

Of course I can't say how I know, so some/most of you will think I am full of it. But that is OK. These are the number I got.

Chess fanatics (like me) will come out of the woods in droves to buy Palms when the best chess programs (e.g., Chess Tiger) are available in native StrongARM code for the Palm OS (version 6 is required, I take it?). The strength of the program is very much tied to the speed of the CPU, all other things being equal.

I already own a couple Palm OS devices and a Pocket PC (stronger chess due to faster CPU). I'll probably sell the latter and buy yet another Palm OS device and finally have a powerful chess analyst and everything else (I use dozens of Palm apps) in one and the same device.

Question about OS 5/6: can an app address substantially more memory than in OS 3/4? (Large hash tables give a big boost to the strength of any chess program; the current limitation on memory access cripples current Palm OS chess apps.)

I have to say that I am very VERY disappointed in not only PALM but the whole palm hardware/software development communities. I have been an avid PALM user since 1996 - yes 1996...and have been holding out for the "killer" palm device. My requirements are pretty plain.

1: Must be able to integrate with Outlook well enough so that I can sync up at the office and while stopped in traffic I can read my emails and put them in their correct folder (1 of 30-40 folders)...then when I return to the office I can sync again and have them all nice and sorted in both places. (PocketPC has this...why after 6-years doesn't PALM?)

2: I like to listen to news, mp3's and online books while I drive and workout. Everyone I know uses for their audiobooks because they are cheaper and can be stored/played on cheap MP3 players. (PocketPC can do all of this INCLUDING AUDIBLE...Palm, Sony, where are you?) admittedly Handspring tried with a simple attempt of a defunct springboard module.

3: Wireless connectivity. I don't want a black and white stripped down i705 to be able to get live data at maybe 1200-baud...I want to be able to bluetooth sync with my ericsson T68 and cruise the internet at 50-80 Kbs. And I don't want to give up my storage options to do so...i.e. Palm's Bluetooth Card (which is too long for the case will hold it.)

4: High resolution screens...PERIOD. I have good eyes and want to see as much as possible at one time. If a PALM cellphone came out with a smaller screen but with high-res screen it would more than make up the screen realestate.

5: I was very excited to read about the new PALM/Phone flip from Kyocera. I don't really care if it runs OS 4 or 5. I thought what a PocketPC and all other palm KILLER it was. It advertised High-Res(come to find out not true), expansion via SD-slot, MP3 player(I was waiting to see if it would support not), and it had the high-speed access seemed to be the real-deal with killer possiblities...until more information kept seeping out. The only thing missing was the EMAIL app.


I know this sounds like a lot of griping...but it is about time that palm matured from a geek-planner (I am one I admit) to a full-fledged PersonalDigitalAssistant.

OS 5 can beat OS 4 because Palm's code was bad

I.M. Anonymous @ 8/26/2002 10:35:11 PM #
If you sign a NDA and take a look on Palm's source code, you will know why OS 5 can beat OS 4 easily.

Palm OS code is very bad, ugly and slow. However, it does not mean OS 5 is good, an application use Palm OS API frequently may get better performance because OS 5's system API run with native arm code. Our own in-house writing routines always beat Palm OS's routines from 2x to 4x even in old Palm's product.

For heavy optimized 68K code, I expected PACE may suffer 1.5x to 20x, even 40x penalty which happens in Java.

Palm's claim will be truth if an application developer use Palm OS's API only. Otherwise, I prefer to use 66MHz Dragonball.

os 5 code is written by the same people that wrote os 4. you wont find that many improvements in the code. the technology that palm has developed that allows 68k applications to run on ARM devices isn't stupid. it was done very well. if the applications use API calls, you will notice significant speed ups. the more the application uses API's, the faster it will seem..

unfortunately, the less API's the developers are using (either due to the fact that they dont do exactly what is needed, or, contain too much error checking etc) will have a negative effect on speeds..

running an application like Liberty (gameboy emu) which uses practically NO API calls - actually runs slower on OS 5 than it does on OS 4.

this is where developers get smart, and, write native ARM code to do the same thing. with a simple recompile and small code change, the OS 5 version of liberty can run 40x faster than the OS 4 version :)

palm is giving developers plenty of warning/assistance with OS 5 development. if you are a developer, you'll know this, and - when users post "this sucks" or, "i want this, and that"; they are just rambling.

palm will let you know whats happening, quit complaining and wait to see what lies ahead. the wait isn't that long. complaints.. its all we seem to hear here.. :(
