1.1 Key Features
The following lists an overview of the MPC8540 feature set.
• High-performance, 32-bit Book E–enhanced core that implements the Power Architecture
— 32-Kbyte L1 instruction cache and 32-Kbyte L1 data cache with parity protection. Caches can
be locked entirely or on a per-line basis. Separate locking for instructions and data
— Memory management unit (MMU) especially designed for embedded applications
— Enhanced hardware and software debug support
— Performance monitor facility (similar to but different from the MPC8540 performance monitor
described in Chapter 18, “Performance Monitor.”
