MPU PowerQUICC III Integrated Processor
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
