Overview

Introduction

The openGFX430 is a synthesizable Graphic controller written in Verilog and tailored for the openMSP430 core.

An example implementation based on the DE0-Nano-SoC and LT24 daughter board from Terasic can be found in the openMSP430 FPGA section (see here).

Features & TODOs

Features

• Support of the following graphic modes:

• 16bpp

• 8bpp
• 4bpp
• 2bpp

• 1bpp

• Smart address generation unit for fast indirect memory access.

• GPU allowing hardware FILL, COPY and COPY_TRANSPARENT operations.
• Supports the LT24 Terasic daughter card.

TODOs

In no particular priority order:

• RTL:

• Add support popular video interfaces (i.e. probably SPI and VGA in addition to LT24).

• Character processing unit.

• Hardware cursor

• Others:

• Add proper block level verification environment.

• Documentation.
