| | | | | In the last part I ended up with a partially working CPU with most of the single-clock instructions implemented. So far, all of the testing was done in simulator only, and it's about time to to get a visual output, so I implemented the display sprite operation next. Other articles in the series: CHIP-8 in FPGA #1 (ALU) CHIP-8 in FPGA #2 (CPU) Display instruction: DXYN The DXYN opcode is described in the original manual as: | |

| | | | | Ive always loved emulators because they let me play old games that I enjoyed as a kid, so I thought it might be fun to learn how they work and how to build one. My real goal is to build an NES emulator, but after doing some research, I decided to take the advice of the internet and start by building an emulator for the much less complex CHIP-8 instead. Its a good stepping stone to the NES. | |

| | | 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. _This is a disclaimer that the VHDL here is probably not the best you will see, but it gets the job done - in the simulator, at least. If you spot any serious errors, or woeful performance gotchas I've fallen for - please let me know at @domipheus. The aim of these posts is to get a very simple 16-bit CPU up and running, and then get stuck into some optimization opportunities later. | ||
