I'm not aware of documentation other than the Xilinx PDFs.  I will admit that I've had a
good deal of previous assembly language experience with (much older) hardware
microprocessors, so I already understood the basics when I picked up PicoBlaze.  I can say
this much - all of the information you need to use PicoBlaze is in those docs, the
instruction set portion is very well written.
