I had a look at the usenet post linked from that site, very impressive!
I'm curious, does this allow you to do cache profiling?  I scanned the 
manual and couldn't determine this.  As a developer I'm far more 
interested in instrumenting my cache use than instruction, or even 
sub-instruction instrumentation.  I realise this requires support in the 
silicon, but I was of the understanding that uSparc had caught up with 
MIP's in this regard?
