Hello all, I'm trying to get Plasma CPU working on Digilent Nexys3 Board. There are 3 RAM Modules, Cellular RAM, Parallel PCM and SPI PCM. SPI PCM is for serial transmission, so It's out of my interest (for now), the rest two are what I'm going to talk about. C-RAM is byte-addressable but P-PCM isn't, for this reason, it can't be directly ported to the Nexys3.
My idea is to make a "helper" module to make the P-PCM byte-addressable, for example, when a byte-addressing write instruction occurs, this "helper" module first reads 16-bit out, then merges 8-bit and rewrite it back to the P-PCM.
According to above method, I noticed that there's "mem_pause" signal on the mlite_module. Can I use this "mem_pause" to cause the CPU paused until "mem_pause" de-is asserted ? Does anyone have some suggestions ?

Thank you,
Tennirva

Hi tennirva,

Can Plasma CPU run in the NEXYS3?
I need to do it but I´m a little missed, can you help me?

I also need to implement a VGA interface and a mouse comunication...

Thank you very much!!!

Not yet, I faced the problem like loading the correct hex file into the RAM. I have stopped developing since months ago, anyway, some developers here might be able to help you. I think each trivial issue will be solved by time.
