DIY CPU built from EEPROM, Counter and lower level logic chips.
This is a very simplified processing unit. It is designed such that you can
- Program instructions on the EEPROM & Execute them in sequence
- You can pass in input through the buttons and see output through LEDs
- This input can be read by the EEPROM, which would change the instruction being ran
- The instruction can modify the output/ modify the program counter (OUTPUT->PC_IN_CTRL1), acting as a JMP statement
Arduino is acting as a stand in clock module.
Components are bought online (using Shopee). PCB Designed using EasyEDA Designer, Manufactured by JLCPCB. EEPROM Programmed using a Raspberry Pi Pico (with a related PCB)
