Bitwise
Bitwise is a computer architecture education kit and a comprehensive set of guides for building a custom CPU, operating system, and compiler from scratch. It serves as a CPU design tutorial and a practical framework for implementing a unique instruction set architecture.
The project provides a custom instruction set architecture toolchain, including resources for creating a matching assembler and compiler. It further includes a hardware development guide for synthesizing computer components and peripheral controllers for deployment on programmable logic devices and FPGAs.
The kit covers full-stack systems engineering, spanning hardware emulation development, operating system implementation with task switching, and the creation of custom compiler toolchains. It includes instructions for building a complete computer system, from the initial hardware logic to the final software stack.
