MPC562/MPC564 Compression Features
The MPC562/MPC564 contains a number of code compression features not found in the
MPC561/MPC563 that function from the burst buffer controller module (BBC) module of the device.
The BBC’s instruction code decompressor unit (ICDU) is responsible for on-line (previously compressed)
instruction code decompression in the decompression on mode. The ICDU contains a 2-Kbyte RAM
(DECRAM) that is used for decompressor vocabulary table storage when compression is enabled or as
general-purpose memory on the U-bus when compression is disabled.

Instruction code on-line decompression is based on an “instruction class” algorithm.
There is no need for address translation between compressed and non-compressed address spaces
— ICDU provides the “next instruction address” to the RCPU.
In most cases, instruction decompression takes one clock.
Code decompression is pipelined:
— No performance penalty during sequential program flow execution
— Minimal performance penalty due to change of program flow execution
Two operation modes are available: decompression on and decompression off. Switches between
compressed and non-compressed user application software is possible.
Adaptive vocabularies scheme is supported; each user application can have its own optimum
vocabularies.
Implemented for MPC56x architecture
Up to 50% instruction code size reduction
No need for address translation tables
