This section provides a high-level overview of MPC8548E
features.
Figure 1
shows the major functional units within
the MPC8548E.
Although this document is written from the perspective of
the MPC8548E, most of the material applies to the other
family members—MPC8547E, MPC8545E, and
MPC8543E—as well. When specific differences occur, such
as pinout differences and processor frequency ranges, they
will be identified as such.
For specific PVR and SVR numbers, refer to the

Key Features
The following list provides an overview of the MPC8548E feature set:
• High-performance 32-bit core built on Power Architecture™ technology.
— 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, with separate locking for instructions and data.
— Signal-processing engine (SPE) APU (auxiliary processing unit). Provides an extensive
instruction set for vector (64-bit) integer and fractional operations. These instructions use both
the upper and lower words of the 64-bit GPRs as they are defined by the SPE APU.
— 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

Overview
— Performance monitor facility that is similar to, but separate from, the MPC8548E 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.
• 512-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.
— Eight-way set-associative cache organization (32-byte cache lines)
— Supports locking entire cache or selected lines. Individual line locks are set and cleared through
Book E instructions or by externally mastered transactions.
— Global locking and Flash clearing done through writes to L2 configuration registers
— Instruction and data locks can be Flash cleared separately.
— SRAM features include the following:
– I/O devices access SRAM regions by marking transactions as snoopable (global).
– Regions can reside at any aligned location in the memory map.
– Byte-accessible ECC is protected using read-modify-write transaction accesses for
smaller-than-cache-line accesses.
• Address translation and mapping unit (ATMU)
— Eight local access windows define mapping within local 36-bit address space.
— Inbound and outbound ATMUs map to larger external address spaces.
– Three inbound windows plus a configuration window on PCI/PCI-X and PCI Express
– Four inbound windows plus a default window on RapidIO™
– Four outbound windows plus default translation for PCI/PCI-X and PCI Express
– Eight outbound windows plus default translation for RapidIO with segmentation and
sub-segmentation support
