Speex split across processors?
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 wil...
