Addresses of Memory and Devices

Addresses of Memory and Devices

Each Silicon Graphics computer system has one or more CPU modules. The CPU reads memory or a device by placing an address on a system bus, and receiving data back from the addressed memory or device. Access to memory can pass through multiple levels of cache.
