# 1.1.2 N64 Control Deck Architecture

As the following illustration shows, the N64 system has four chips at its core:

- CPU (Central Processing Unit) chip
- RCP (Reality Co-Processor) chip
- Two RDRAM (main memory) chips

The CPU and RCP work together to process the game program. They can both be executing at the same time. Each process they execute is called thread and task accordingly.
