EM8623 is an ARM7 I believe, with no MMU. For SMP8634 and beyond, they switched to MIPS with MMU :-) The codesourcery toolchain uses ARM EABI, but the Sigma Designs libraries as OABI, so watch out. You have to use the right compilers... > I need to create a media player and include web connectivity (very thin web > client). Do I use CLDC or CDC? It could come down to size constraints, > though. Your main constraint will be memory, indeed. Max RAM with EM8623 is 128MB, and some portion, about 40MB, must be kept separate for video. That does not leave much for a web browser, if you have high-resolution pictures or large fonts. It'll be a squeeze. But it is just about enough for basic pages. I predict your biggest problem after getting a browser will be memory fragmentation, which prevents all the memory being used with 100% efficiency - especially when streaming video and/or switching between complex web pages. By the way, there are some non-Java web clients for these devices. Opera is available, that's probably good. Some others look less good, but it depends what you're displaying. > I was told codecs are included in the processor. Is that possible, or just > marketing talk? There are several codec co-processors in the chip, connected to the ARM part. They are quite good, for the price, although struggle a bit at the highest resolutions. You need to load codec binaries, but they are loaded into the co-processors which are specially designed for it; they don't do much on the ARM itself. > I'm asking the manufacturer about RAM sizes.
