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.
NumOS is an open-source operating system for graphing scientific calculators based on the ESP32-S3 microcontroller, featuring a Giac-backed CAS engine and LVGL 9.x interface.
