Microblaze and Picoblaze
2005-02-08 06:45:00
Hi Everybody,
I wonder some thing about microblaze and picoblaze.
*I must buy some tools for use microblaze or picoblaze? I think I must
buy Xilinx EDK for microblaze.
*EDK includes C/C++ compiler? or any?
*There are advantages at Debugging?
*If I use microblaze, FPGA'll be only processor? or ...

As of today, could anyone tell me:
1) Are Xilinx tools for FPGA design, especially microblaze, actually, solid,
good, usable?
2)Does anyone has RTOS experience with microblaze?
If yes, which one?
Please comment the answer.
Thanks.
