MPC8544E Overview
Figure 1. MPC8544E Block Diagram
— Double-precision floating-point APU. Provides an instruction set for double-precision (64-bit)
floating-point instructions that use the 64-bit GPRs.
— 36-bit real addressing
— Embedded vector and scalar single-precision floating-point APUs. Provide an instruction set
for single-precision (32-bit) floating-point instructions.
— Memory management unit (MMU). Especially designed for embedded applications. Supports
4-Kbyte–4-Gbyte page sizes.
— Enhanced hardware and software debug support
— Performance monitor facility that is similar to, but separate from, the device performance
monitor
The e500 defines features that are not implemented on this device. It also generally defines some features
that this device implements more specifically. An understanding of these differences can be critical to
ensure proper operations.
256-Kbyte L2 cache/SRAM
— Flexible configuration
— Full ECC support on 64-bit boundary in both cache and SRAM modes
— Cache mode supports instruction caching, data caching, or both.
— External masters can force data to be allocated into the cache through programmed memory
ranges or special transaction types (stashing).
– 1, 2, or 4 ways can be configured for stashing only.
