| | | | | Ive been getting into FPGAs lately. Last year I built an FPGA version of Ben Eaters breadboard computer, but Ive been wanting to do a more advanced project to help me gain experience with Verilog and FPGAs in general. For his breadboard computer, Ben Eater followed the design laid out in a book called Digital Computer Electronics by Malvino and Brown. The book builds what it calls the Simple-as-Possible (SAP) Computer. | |

| | | | | Continuing with the implementation of CHIP-8 in Verilog, I wanted to continue with the CPU module and get it to actually execute some instructions, so we'll build an instruction decoder, CPU states and a register file. As described in the previous part , we would like to: fetch instruction (2 bytes) from the memory into an 16-bit opcode register decode the instruction execute the instruction Other articles in the series: | |

| | | | | It's a simple question really: how can you read and write to the same register in a single-cycle processor? If you have spent most of your life working with software, it is tempting to think of all events as happening sequentially. However, that sequential model that we have become so familiar with as software engineers is really an abstraction that hardware offers to us to help our simple brains reason about logic. | |
