fpga cpu

Hello experts. I have heard that it is possible to simulate with FPGA a CPU (registers, ALU, accumulator, memory, pointer stack, etc) with a small assembler command set in order to perform mathematical operations. Is this possible? Any hints?

My goal is to generate a calculator (basic operations), by typing the operands via ps2 keyboard and show the results on a VGA display. My idea is to use FPGA as a microprocessor that manages the all logic and the I/O communications (keyboard, video, RAM)

I'd truly appreciate If you could point me to the right direction on how I can accomplish this project.

Best Regards
Pedro
 

fpga cpu core

Hi,
please check PicoBlaze from xilinx, its a small 8-Bit uP/uC with many applications.


thanks

how to create a cpu

you can get a workable cpu code from xilinx website or www.opencores.org,

then compile them and your program object source in a FPGA design environment

and downloadload them into FPGA. then it will work.

Thank you all for your suggestions.
 

Re: fpga cpu

The J1 is a very small FPGA CPU with memory, stack, etc, in under 200 lines of Verilog. The version here:

The J1 Forth CPU

also has a VGA display interface.
