| | | | | This is part of a series of posts detailing the steps and learning undertaken to design and implement a CPU in VHDL. Previous parts are available here, and I'd recommend they are read before continuing. Memory Operations We already have a small RAM which holds our instruction stream, but our TPU ISA defines memory read and write instructions, and we should get those instructions working. It's the last major functional implementation we need to complete. The fetch stage is simply a memory read with the PC... | |

| | | | | Ive went through the first part of From Nand to Tetris course where I learnt to build a simple 16-bit computer called Hack from the digital building blocks (NAND gates). The course used its specific HDL (hardware definition language), which is a gentle way to shield a beginner from the ugliness of a real language, but to implement anything on a real FPGA board one needs to use VHDL or Verilog. | |
