RE: New CPU
For a viable commercial product I would expect the CPU to be first of all the cheapest one that meets the minimal horsepower requirements, and obviously other considerations, such as power consumption. Would you prefer to run Microsoft office for 30s or have your battery last for a week?

I don't know if there were any discussion about this. Today I was looking at the processor and I saw (sadly) that it's got only 200-266MHz. Do you think it is going to enough? I get the info from: http://wiki.openmoko.org/wiki/Neo1973_Hardware#Processor I am guessing that the core team is planning to put a faster CPU in. Do you think, that this CPU would be better? http://www.samsung.com/products/semiconductor/MobileSoC/ApplicationProcessor/ARM9Series/S3C2443/S3C2443.htm What CPU are they planning to use?

Second-hand reports from those lucky enough to have phones indicate that the current software could use optimizing to run on it nicely. OTOH, it's apparently just about video capable, which is nice: http://wiki.openmoko.org/wiki/Video_Player I am guessing that the core team is planning to put a faster CPU in. It's been mentioned that the P1+/2 revision will likely have a faster CPU; final specs have been promised at the same time P1 sales will start, hopefully soon :] -- Mikko Rauhala - [EMAIL PROTECTED] - URL:http://www.iki.fi/mjr/ Transhumanist - WTA member - URL:http://www.transhumanism.org/ Singularitarian - SIAI supporter - URL:http://www.singinst.org/ ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

From the page, the newly suggested SoC is very new, in fact newer than the original release date for the Neo1973. I don't think anyone at FIC would consider swapping out such a crucial element of the system at this stage of development, even if it would be cheaper and faster and more energy efficient at the same time. Would you prefer to run Microsoft office for 30s or have your battery last for a week? I would need to check the specs for details, but the newer core runs is fabricated in 0.13u instead of 0.18u and needs 1.3V+ instead of 1.8V+, those are actually signs that this core does not necessarily consume more power even though it has more MHz (also take into account improved power saving schemes). Also #2, MHz do not indicate speed. They indicate clock rate. 266MHz could be not enough and plenty at the same time depending on what you do with it and what the underlying architecture is. ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: New CPU
Yes. Some CPU is few clock cycles on calculations, others are optimized for I/O. The important thing is how many clock cycles it will use in average on an instruction. For video and audio, lets hope it is fast with mathematics. For power, maybe we can change the freq. with software (something simmular to cpyspeedy) ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
