I am interested in using Speex in an embedded system built around an ARM microcontroller. I have seen other posts indicating that Speex can run in real-time on some iPAQ PDA's, but these are using a StrongARM 166MHz processor. I'm looking more at the chips from Atmel (SAM7), Philips (LPC2xxx), and TI (TMS 470), which are ARM7TDMI with on-chip SRAM and flash, running at speeds of 33 to 60MHz. 166 down to 60 is a big drop, but I'm hoping to gain performance due to lack of wait states (no external memory), and the lack of any O/S running to eat cycles; the chip will only be encoding...
