PowerPC 603e RISC Microprocessor Technical Summary
2.3 Instruction Set and Addressing Modes
All PowerPC instructions are encoded as single-word (32-bit) opcodes. Instruction formats are consistent
among all instruction types, permitting efficient decoding to occur in parallel with operand accesses. This
fixed instruction length and consistent format greatly simplifies instruction pipelining.
2.3.1 PowerPC Instruction Set
The PowerPC instructions are divided into the following categories:
Integer instructions—These include computational and logical instructions.
— Integer arithmetic instructions
— Integer compare instructions
— Integer logical instructions
— Integer rotate and shift instructions
Floating-point instructions—These include floating-point computational instructions, as well as
instructions that affect the FPSCR.
— Floating-point arithmetic instructions
— Floating-point multiply/add instructions
— Floating-point rounding and conversion instructions
— Floating-point compare instructions
— Floating-point status and control instructions
Load/store instructions—These include integer and floating-point load and store instructions.
— Integer load and store instructions
— Integer load and store multiple instructions
— Floating-point load and store
— Primitives used to construct atomic memory operations (
lwarx
and
stwcx.
instructions)
Flow control instructions—These include branching instructions, condition register logical
instructions, trap instructions, and other instructions that affect the instruction flow.
— Branch and trap instructions
— Condition register logical instructions
Processor control instructions—These instructions are used for synchronizing memory accesses
and management of caches, TLBs, and the segment registers.
— Move to/from SPR instructions
— Move to/from MSR
— Synchronize
— Instruction synchronize
— Order loads and stores
Memory control instructions—These instructions provide control of caches, TLBs, and segment
registers.
— Supervisor-level cache management instructions
— User-level cache instructions
— Segment register manipulation instructions
— Translation lookaside buffer management instructions
