Key Features

The following list provides an overview of the device 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 to 4-Gbyte page sizes.

— Enhanced hardware and software debug support
