16-bit VHDL Toy Microcontroller

This was a small passion project I developed after learning about hardware design in a lab a couple of years ago - it's a 16-bit microcontroller written in VHDL using the Aldec Active-HDL software.

Since I wrote this as one of my very first hardware design projects, I wrote it with two concepts in mind:

• Simplicity - both so I could write it, and so I could explain it to others starting out like me
• Extensibility - so that you can add your own stuff
  • (There are seven bits in total to specify what kind of instruction to execute, and I didn't come close to using all of them!)

Sections

This project is split into two main sections:

• The assembler (see Assembler/), which is written in Python.
• The microcontroller itself (see src/), which is the actual VHDL design.

Documentation for the assembler can be found in Assembler/specifications/. Documentation for the microcontroller's instructions & ALU opcodes can be found in overall_docs/.
