Yes - ADuC processors are pretty cool. 4x 12-bit DACs on-chip is a 
really nice feature. I did some small projects with these guys a few 
years back but was never too happy with the speed. The main things that 
bugged me were the wait states on memory accesses, IRQ latency (hundreds 
of cycles!) and the SPI port clock maxes out at ~3MHz. A new spin with a 
more modern ARM core (Coretex M4 anyone?) and faster memory would be a 
good thing.
