MPC562/MPC564 Compression Features
A.2.4
During the compression process, compressed instructions change their location in the memory and are not
word aligned. Displacement fields in the direct branch instructions have to be updated by the compression
tool to make compressed instruction addressing possible. Four LSB bits of the displacement immediate
field (LI or BD) in the compressed direct branch instructions are used for bit addressing in the 32-bit
memory word. The remaining bits of the fields are used in the branch target calculation of the base address
(word address). The RCPU branch unit copies the bit pointer into the IP field of issued compressed branch
target address. The branch compressed target base address is calculated according the direct branch
addressing mode.
If a branch has absolute addressing mode, the branch target base address is calculated as a sign extension
of the base address portion of the LI (or BD) field.
If a branch has relative addressing mode, the branch target base address is calculated as a sum of the base
address of the branch and sign extended base address portion of the branch LI (or BD) field.

address for the unconditional branch has 20 bits This yields an unconditional branch displacement limit of
4 Mbytes. The word pointer for the conditional branch has 10 bits. This yields a conditional branch
displacement limit of 4 Kbytes.
