Dear helper, I am implementing a new processor in verilog. I am no near the execution unit implementation!! Does any one have (or know) a full design of RISC-style instructions execution unit in verilog. I am planning to implement 1 ALU unit, 1 Branch unit, 1 SET unit, and 1 LDST unit. I really need the unit..please help. /Ben UEC, IS , Tokyo |

If you google you shall find. As well, the XR16 in the XSOC Kit (http://fpgacpu.org/xsoc/) includes a Verilog implementation. As a schematic design came first, it is quite structural, and so I don't put it forth as a *good* example of Verilog. There is also a simpler, annotated Verilog RISC processor datapath in the article at http://www.fpgacpu.org/papers/soc-gr0040-paper.pdf. See also the accompanying slides http://www.fpgacpu.org/papers/soc-gr0040-slides.pdf. At least one Verilog textbook includes a RISC processor design. Jan Gray |
