A soft processor is an Intellectual Property (IP) core that is implemented using the logic primitives of the FPGA. Key benefits of having a soft FPGA-based processing system are re programmability and re-configurability. There are various soft-core processors provided by different vendors such as Microblaze (Xilinx), NiosII (Altera), OpenRISC (developed by OpenCores), etc. Microblaze processor is one of those soft-core processor developed by Xilinx which models specific processor using HDL and can be customized (and synthesized) for any application. The Microblaze soft processor is a soft 32-bit RISC processor.
