This document gives an overview of the MPC750 and MPC740 microprocessor features, including a block diagram showing the major functional components. It summarizes how the MPC750 and MPC740 processors implement the PowerPC® architecture specification and describes processor-specific features not defined by the PowerPC architecture. This document has two parts: • Part 1, “MPC750 Microprocessor Overview,” provides an overview of MPC750 features, including a block diagram showing the major functional components. • Part 2, “MPC750 Microprocessor: Implementation,” describes the PowerPC architecture in general and provides specific details about the MPC750 as a lowpower, 32-bit implementation of the PowerPC architecture.
