The wireless chipset contains among other things a full ARM core :-) I kid you not :-) amonng possibilities this means - cool wireless hacks and maybe even using it for computation when not using it for wireless __________________ Annoying me is NOT an approved way of encouraging me to produce software My software:PowerSDHC, PowerDrive, nuRom, UDMH, warpSpeed, PowerDiGi, brightnessFix, etc...

JavaJiveJump Behold the Elixir of Life Join Date: Jun 2003 Posts: 931	:-) Where do you research this stuff? It's hard to believe Palm documents this for the public? You have access to some whitepapers? This is sweet information! How will you take advantage of it?

Those data sheets outline all the capabilities of the chips, not just the ones being used by the product you currently have. __________________ My Palm family: Palm T\|X ~ Palm T\|E ~ m130 ~ m125 ~ POSE

_Em Beta Tester Join Date: Nov 2005 Location: Igloo Posts: 2,377	What part number does that chip have, Dmitry? I'm interested in seeing cache numbers, max speed, etc. so we can tell how much on-board codespace is available. This could be useful for writing a "soft" graphics coprocessor that can mimic the Zodiac's to some degree __________________ My Palm family: Palm T\|X ~ Palm T\|E ~ m130 ~ m125 ~ POSE

good luck
the specs for it only say wofo chip
u cannot access the ARM part of it except with custom firmware, which i managed to upload to it

palmmann Registered User Join Date: Mar 2008 Posts: 36	it's there, but is it useful? could it be used to, say, conserve battery using it instead of main proc for things like calc, notepad, etc? i wouldn't think it would be that powerful, and could using it interfere with normal wifi use? would writing the drivers be worth the effort? sorry but things like this fill me with questions. any way this is a pretty cool find

dmitrygr Software engineer/hacker Join Date: Jan 2004 Location: Silicon Valley, CA Posts: 5,061	using it instead of main processor is impossible. it is not interfaced to the lcd, etc using it is hard as is since i have no idea what its internal registers are and what they mean. its a custom ARM core with no docs to it. not easy to reverse engineer that __________________ Annoying me is NOT an approved way of encouraging me to produce software My software:PowerSDHC, PowerDrive, nuRom, UDMH, warpSpeed, PowerDiGi, brightnessFix, etc...
