IBM CPU Microblaze
solvall,
basically Microblaze is a soft core processor by xilinx which allows you to reconfigure your hardware design by just selecting the peripharals for your hardware design and later this PSOC (Programmable Systems Of Chip) generates automatically VHDL code for your selected 8/16/32 bit processor in Vertex FPGA. You can see the VHDL code also.
After design is ready you can use this programed FPGA and can either use Microblaze/power PC for your embedded applications with ported RTOS.
