▤ Summary

This article describes the development of a custom 16-bit FPGA-based computing platform and the software stack built for it. It walks through the architecture, instruction set, memory model, and rendering approach used to run graphics-heavy demos and simple games on low-cost FPGA boards. It also compares different FPGA targets and discusses performance tradeoffs such as LUT usage, frame rates, and DMA-driven rendering. The piece emphasizes tooling and implementation details in Verilog and SystemVerilog, along with experiments in Python-based tooling and simulation. The overall focus stays on engineering progress and system design rather than a business event.
