2. Features Overview
The following list provides an overview of the PC8548E feature set:
• High-performance 32-bit Book E–enhanced core that implements the PowerPC
®
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, 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
– Performance monitor facility that is similar to, but separate from, the PC8548E 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
