® 845MP/845MZ Chipset System Block Diagram

The Intel 845MP/845MZ Chipset Memory Controller Hub-M (MCH-M) is designed for use with the

Mobile Intel Pentium 4 Processor-M. The Intel 845MP/845MZ Chipset MCH-M manages the flow of

information between its four interfaces: the System Bus, the memory interface, the AGP port, and the hub

interface. The MCH-M arbitrates between the four interfaces when each initiates an operation. While

doing so, the MCH-M must support data coherency via snooping and must perform address translation

for access to AGP Aperture memory.

The Intel 845MP/845MZ Chipset Memory Controller Hub-M (MCH-M) may contain design defects or

errors known as errata, which may cause the product to deviate from published specifications.
