A hardware implementation of the Consolite game console written in Verilog.

Consolite Hardware

This is a Verilog implementation of a microprocessor implementing the Consolite ISA. It is designed for the Mimas V2 development board with a Spartan 6 FPGA.

What Is Consolite?

Consolite (coming from "Console Lite") is the name I've given to my design of a hobbyist microprocessor and associated toolchain. Consolite's instruction set architecture (ISA) has assembly level instructions for setting colors, drawing pixels on the screen, and receiving input. This makes it suitable for writing games, which is what makes it a "console".

Consolite Specs

• Display: 256 x 192 pixels, 8-bit color (VGA output)
• Registers: 16 general purpose, instruction pointer, color, flags
• Memory: 64KiB main memory, 48KiB video memory (write only)
• Storage: Up to 256 programs on microSD card
• Input: 6 buttons, 8 switches, 32 GPIOs, up to 8 SNES controllers

Documentation
