32-bit single cycle CPU design and implementation of the "Asteroids" arcade game for this CPU in Assembly and C.

FPGA-Asteroids

This repository contains a CPU design for use on FPGAs and a clone of the Asteroids arcade game (written in assembly by hand) that runs on the CPU.

CPU Design

In short, the CPU is a 32-bit single cycle processor and supports

• A subset of the MIPS instruction set
• Accelerometer input
• Keyboard input
• VGA display output (640x480 @ 60 Hz)
• Mono audio output
• LED lights output
• 7-segment display output

More information can be found in the CPU README.

Asteroids

The assembly version runs on the CPU clocked at 100 MHz (with support for on-the-fly underclocking to 25 or 50 MHz to demonstrate VBLANK).

A prototype written in C that writes directly to the Linux framebuffer is also available.

More information can be found in the Asteroids README.
