RTEMS on Altera NIOS processor

For what it's worth we looked at both the MicroBlaze and the NIOS for a 
project here.  Neither had the performance we needed (we ended up using a 
hardcore processor) but in comparing MicroBlaze to NIOS, the NIOS seemed to 
be a few years ahead of MicroBlaze in terms of usability and readiness for 
production use.

   We use Altera logic here, not Xilinx, so I may have a slight bias 
towards Altera stuff but the MicroBlaze V2.1 really seemed to be too early 
for production use.  MicroBlaze V2.2 completely broke the development 
station.  YMMV but I recommend trying it before buying it...
