The Wii's hardware is one of the most well-understood of any home console. Due to extensive research in the homebrew community, the Wii's inner workings have been reverse-engineered and have been exploited heavily in the usage of homebrew.

Processors

The Wii has three processors. The main processor of the Wii's system, codenamed Broadway, which is a PowerPC processor that does the job of running executable code, and interfacing with legacy hardware, which includes every aspect of the Gamecube's system, with a few exceptions, which are handled by the PowerPC. The Broadway is also called the PPC, because that is its architecture.

The second processor is a custom macronix 16-bit dsp that does side task jobs for boot, audio, memory card unlocking, gba decryption, etc.

The third processor is nicknamed the Starlet chip, due to the fact that it lives inside the Hollywood graphics processor. The Starlet is an ARM processor that communicates with hardware, as well as the DVD drive. The program that handles communication between the PPC and the hardware is known as IOS, and exists for security.

NAND is the term for the Wii's internal flash memory, which is based on a NAND flash.

Notes

1 & 2. Certain devkits such as the NDEV have higher memory than retail Wii systems.

3. Not seen on certain devkits such as NDEV and RVT-H.

4 & 5. Not seen on Wii mini units.

6. MXIC DSP hardware can be seen here Macronix DSP.
