Dear All friends

I have a simple microprocessor core. I want to add some memory mapped IO to it. Is there any sample code (verilog) for this type of IO? Or any implementation suggestion?

Hi,

refine your question.
You want code for: The microprocessor, the core, the interface, the periferal?
What interface type, speed, datawidth?

Btw: Don´t expect a response is more detailed than your question.

You always can have a look into existing opensource cores.

For example, darkriscv has some general I/O mapped into specific memory addresses for debug.

I already have the core. I want to add some mapped IO to existing core.
