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 I can write built in USB, ethernet etc.? *If I use Microblaze I must use only Virtex or Spartan 3?...

I'm investigating if the microblaze is an option for a project where physical space is extremely limited. Perhaps somebody can answer the following: 1.Is it possible to use the microblaze in a spartan3E 500? If yes, how much will it eat from this device? 2.if yes, is it possible to use the microblaze without any other memory chips (except one serial bootrom) and still running a standalone pr...

I have used sysgen to build a model with microblaze, but i don't know the difference between the two functions: microblaze_nbwrite_datafsl and microblaze_bwrite_datafsl. Will the later function stop the microblaze until finishing writing operation? thanks. moreover, can i debug my c source code of microblaze in sysgen? if so, how?

Hi, all. Is it known to be possible to create a Microblaze system without the OPB? For example, say I have 1 MicroBlaze with 16KB of d&i BRAM, but I don't necessarily need the off-chip SDRAM or UART (or any OPB slave peripheral at all), so I don't include the OPB. And say it's part of a larger network to justify not needing the OPB for any peripherals. Currently, my 8.2 version has an...

Hi guys, I'm trying to connect a simple co-processor to microblaze. The co-processor simply gets 8 inputs and does a simple arithmetic and gives one output.

So the co-processor never notices that there are ...
