[hpsdr] Using an XMOS chip in an SDR

[Leon]

I'm very interested in the XMOS chips:

http://www.xmos.com

I'll be getting one of the $99 XC-1 dev kits next week, and will get another
at a seminar in London later in the month. Four 400 MIPS cores delivering a
total of 1600 MIPS on a credit-card sized board will have some interesting
applications.

The XMOS cores have DSP functionality and include a large accumulator and
DSP primitives like a MAC.

An XC-1 could form the basis for a very compact SDR which doesn't need a PC,
using a Softrock with the XC-1 doing all the baseband processing. All that
would be needed is an AF amp on the output from the XC-1. For better audio
quality a codec could be used.

For a really high-performance SDR the XMOS chip is fast enough for it to be
interfaced to an ADC, without needing an FPGA. One core could do all the
high-speed stuff, and another core could do the baseband processing,
resulting in a two-chip radio.
