The VGA module produces the hsync, vsync and RGB values that a monitor requires.Ĭontroller - A program runs on a host computer which transfers serial data to the FPGA.
It is faster than performing repeated Loads and Stores in the CPU.ĭisplay Memory and VGA - The PPU writes to the display memory, which is subsequently read out by the VGA module. At boot, CPU starts reading programs at the address 0xFFFC.ĭMA - The DMA transfers chunks of data from CPU address space to PPU address space. It is responsible for controlling all other modules in the NES. It receives memory mapped accesses from the CPU, and renders graphics from memory, providing RGB values.ĬPU - Our CPU is a 6502 implementation. PPU - The PPU(Picture Processing Unit) is responsible for rendering graphics on screen. Our report has a section dedicated for each of these modules. Here is an overview of each module in our design. Much of the information was gleaned from, and from other online forums that reverse engineered the NES. The following sections will explain the microarchitecture of the NES. In addition, we wrote our own assembler and tic-tac-toe game to test our implementation. In order to exactly recreate the original console, we needed to include memory mappers, an audio processing unit, a DMA unit, a VGA interface, and a way to use a controller for input. Our goal was to recreate the CPU and PPU in hardware, so that we could run games that were run on the original console.
Nintendo chose to use the 6502 processor, also used by Apple in the Apple II, and chose to include a picture processing unit to provide a memory efficient way to output video to the TV.

The NES has been recreated multiple times in software emulators, but has rarely been done in a hardware design language, which makes this a unique project. Our motivation is to better understand how the NES worked from a hardware perspective, as the NES was an extremely advanced console when it was released in 1985 (USA). This decision led to higher quality games and helped to sway the public opinion on video games, which had been plagued by poor games for other gaming consoles. Nintendo required that restricted developers from publishing games without a license distributed by Nintendo. A majority of its early success was due to the relationship that Nintendo created with third-party software developers. Following a slow release and early recalls, the console began to gain momentum in a market that many thought had died out, and the NES is still appreciated by enthusiasts today.
