I built a RISC CPU in Excel

A user shares their experience of building a 16-bit RISC CPU in Excel, explaining the improvements made to enhance performance and reduce the system's size. The new architecture includes a minimal instruction set, a stack mechanism, and adopts Harvard architecture. The goal was to avoid using visual basic scripts and if statements to improve computation speed. The CPU now runs around 10 times faster and occupies only a fraction of the original footprint. The project files and documentation are available on GitHub.
