32-bit CPU built on Power Architecture™ technology
Freescale Variable Length Encoding (VLE) enhancements for code size footprint reduction
Thirty-two 64-bit general-purpose registers (GPRs)
Memory management unit (MMU) with 32-entry fully-associative translation look-aside buffer
(TLB)
Branch processing unit
Fully pipelined load/store unit
32 KB unified cache with line locking
— Four or eight-way set associative
— Two 32-bit fetches per clock
— Eight-entry store buffer
— Way locking
— Supports assigning cache as instruction or data only on a per way basis
— Supports tag and data parity
Vectored interrupt support
Interrupt latency less than 70 ns @ 132 MHz (measured from interrupt request to execution of first
instruction of interrupt exception handler)
Reservation instructions for implementing read-modify-write constructs
(internal SRAM and Flash)
Signal processing engine (SPE) auxiliary processing unit (APU) operating on 64-bit general
purpose registers
Floating point
— IEEE® 754 compatible with software wrapper
— Single precision in hardware; double precision with software library
— Conversion instructions between single precision floating point and fixed point
Long cycle time instructions, except for guarded loads, do not increase interrupt latency in the
MPC5561; to reduce latency, long cycle time instructions are aborted upon interrupt requests.
Extensive system development support through Nexus debug module
Four master ports, six slave ports
32-bit address bus, 64-bit data bus
