Lpc2000

Maybe not as good as ADI's DSPs, but probably
better than some low-end DSPs (for example Microchip's
rfPIC). There are some drawbacks, of course (no
hardware loops, lack of division, no special
addressing modes), yet I believe it should perform
quite well for medium complexity DSP algorithms.
