README
README.mduCPU
This is a 16bit pipelined CPU designed on a breadboard and produced in modular component boards.
My objective in this project is to learn electronics, CPU design and build a fully functional CPU that can be updated, added to and further developed easily.
The CPU is designed around
- four general purpose 16 bit registers
- four 16 bit address registers
- ALU supporting addition, subtraction, shift and bitwise operations
- piplined instructions
- banked memory with a base of 64k, expandable to about 1.5 megabytes (max TBD)

Questions
How big is the AddressRegisterModule PCB?
It measures 100 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AddressRegisterModule use?
62 parts, built around the 74LS245SC, 74LS193P-E and 74LS00SC. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the AddressRegisterModule KiCad files?
From the crempp/ucpu repository on GitHub, at the commit this page was made from: the board is cpu/AddressRegister/AddressRegisterModule.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AddressRegisterModule design in my own project?
Its repository states no licence, so its author keeps all rights: ask crempp before reusing the design.
