| | | | 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.

| | | | CHIP-8 is one of the most popular target architectures for aspiring emulator writers. Im planning to implement it in hardware, so I thought that writing a software emulator/interpreter would be enlightening. I was also looking for some practice before implementing CHIP-8 in hardware in Verilog :) CHIP-8 Virtual machine description: 64x32 pixel monochrome display 4K of 8-bit RAM 16 8-bit variable registers V0-VF I 16-bit address register Stack of 16-bit addresses for call/return 16-bit PC - program counte... | |
