It is the CORDIC implementation in Verilog. CORDIC is a hardware algorithm (CORDIC 硬體演算法) based on simple additions/subtractions and bit shifts. It can compute trigonometric, hyperbolic, exponentials, logarithms, multiplication, division, square, and square-root. And which is widely used in DSP, embedded systems and FPGAs fields.

A hardware-first exploration of Advent of Code 2025, implementing each puzzle as a cycle-accurate FPGA design in Hardcaml, using streaming UART I/O, explicit memory pipelines, and finite-state schedulers instead of software control flow.
