What is mean by picoblaze microcontroller?

Answer 1

hi,

Well, PICOBLAZE and MICROBLAZE are embedded soft core RISC processors from Xilinx for their FPGAs. P.B is an 8-bit micro controller s.c and M.B is a 32-processor soft core. These core are I.P s and won't appear in our designs unless we enable it(in CoreGen).

These cores use the glue logic in your FPGA and become available by enabling, leaving some space for your design and routing. i.e one can use an entire FPGA logic for your design when you don not need theses processor cores.

NIOS is a soft core from ALTERA for their FPGAs.

POWER PC is an Embedded 32-bit RISC processor hard core in Virtex family FPGAs which is designed by removing some CLB and embedding the POWER PC core. Here the hardcore consumes your FPGA resources even though you do not use them in your design. This core is physically available-hence hardcore.
