The submission for GFMPW0 includes the following components:\n\n- SM83 (GBZ80) CPU core\n- Pixel processing unit\n- Programmable sound generator\n- Timer\n- Stereo PDM audio output\n\nTo form a complete GB system, users need to provide the following additional components:\n\n- Generic 16KB Async SRAM\n- Some buttons for input\n- 160x144 LCD\n- Low pass filter and audio amplifier\n- Unmodified GameBoy game cartridge\n- Small amount of glue logic\n\nThe simtop.v maybe used as a reference on external components required.\n\nA Verilator-based testbench is provided in verilog/sim.\n\n## Implementation Results\n\nThe implementation has 43% ultilization of a 1.5mm x 1.5 mm core area. The Fmax is around 20MHz at typical corner, 3.3V with no hold violation. The design is supposed to run up to 4MHz at 5V.\n\n## License\n\nUnless otherwise stated, HDL codes are licensed under OHDL 1.0, and software codes are licensed under MIT.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzephray%2Fvb-gfmpw0","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fzephray%2Fvb-gfmpw0","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzephray%2Fvb-gfmpw0/lists"}
