cpu-design

A detailed blog series documenting the design and implementation of a scientific calculator from scratch using FPGA, covering numerical methods, CPU architecture, microcode, and hardware prototyping.

This project implements a fully functional scientific calculator in hardware using an FPGA, including a custom soft CPU, microcode firmware, and supporting tools. It provides a web-based simulator and open-source Verilog code.

An article detailing the hands-on assembly and testing of a TD4 4-bit CPU based on the book 'How to Build a CPU' and open-source PCB designs.
