I am evaluating using the Altera Cyclone with Quartus SOPC vs. Xilinx Spartan3E and PicoBlaze. I need a soft core processor and I think PicoBlaze would be enough. SOPC and Nios-II is very powerful but the learning curve looks like a potential nightmare to me. In order to use SOPC I might have to get involved writing custom components to do the job and then one has to master the Avalon inte...

Gang I created a half dozen example projects using ISE 8.2i and the PicoBlaze on my S3-1600 Dev Board. I'm really comfortable with asm programming so the lack of a C compiler was no big deal. I am running under Windows XP SP2 on a dual cpu P6 @ 1.8GHz and 2GB of RAM. Now I have started using the XPS 8.2i with ISE 8.2i so that I can do some MicroBlaze programming in C. I am creating some...

Hi everyone, I just installed a new workstation, a Core2 duro running linux 64 bits. But I can use data2bram on it, it crashes every time. I've tested with both 8.2 and 9.1 (both with latest service pack). For 8.2 I even tried the 32b and the 64 version. Using this utility is really important for me to update picoblaze and microblaze software without a need to recompile each time I want to ...

Hello All, I'm on a project which has ballooned in scope such that it calls for implementing the MicroBlaze (originally it called for a straight forward PicoBlaze, but that's a long story ...) I have successfully created custom peripherals and have implemented the code to control them from my device MMI. Thus, I'm mildly savvy wrt Xilinx EDK. However, I cannot get my SPI (EEPROM) periphe...

Hello, I have defined some signals which I plan to change dinamicaly with MicroBlaze as submodule. Signals are organized as arrays and I will use one index and one data port to access them (like PicoBlaze IO ports). What is the best way of interfacing these signals between the MicroBlaze and the top level?

Hello, in my actual design im using a few picoblazes. Now I wonder if it is possible to update the code in the bitstream without a new implementation run like it is possible with the microcblaze.
