PicoBlaze Overview and PicoBlaze Manual and User’s Guide

EBook Description: The PicoBlaze solution consumes considerably less resources than comparable 8-bit microcontroller architectures. It is provided as a free, source-level VHDL file with royalty-free re-use within Xilinx FPGAs. Because it is delivered as VHDL source, the PicoBlaze microcontroller is immune to product obsolescence as the microcontroller can be retargeted to future generations of Xilinx FPGAs, exploiting future cost reductions and feature enhancements.

Benefits of HDLs:
• Early design verification via high level design verification
• Evaluation of alternative architectures
• Top-down design (w/synthesis)
• Reduced risk to project due to design errors
• Design capture (w/synthesis & independence of implementation media)

PSIM: Processor SIMulator (version 4.2)

A simulator for a basic stored program computer architecture is described which graphically displays the architecture while showing the detailed operation on a per clock cycle basis. The instruction set consists of sixteen instructions that can be combined to form many capabilities including conditional branching.
