3.10.2 Recommended Simplified Mnemonics
3.10.3 Calculating Effective Addresses
MPC555
USER’S MANUAL
To simplify assembly language coding, a set of alternative mnemonics is provided for
some frequently used operations (such as no-op, load immediate, load address, move
register, and complement register).
For a complete list of simplified mnemonics, see the
(RCPURM/AD). Programs written to be portable across the various assemblers for the
PowerPC architecture should not assume the existence of mnemonics not described
in that manual.
The effective address (EA) is the 32-bit address computed by the processor when ex-
ecuting a memory access or branch instruction or when fetching the next sequential
instruction.
The PowerPC architecture supports two simple memory addressing modes:
These simple addressing modes allow efficient address generation for memory ac-
cesses. Calculation of the effective address for aligned transfers occurs in a single
clock cycle.
• EA = (rA|0) + 16-bit offset (including offset = 0) (register indirect with immediate
• EA = (rA|0) + rB (register indirect with index)
