Assembler language reference. The Assembler Language Reference topic provides information about the assembler program that operates within the operating system. The assembler takes machine-language instructions and translates them into machine object code. What's new in Assembler Language Reference.
This chapter lists the MPCxxx instruction set in alphabetical order by mnemonic. Note that each entry includes the instruction formats and a quick reference 'legend' that provides such information as the level(s) of the PowerPC architecture in which the instruction may be found—user instruction set architecture (UISA), virtual

Jul 1, 2002 PowerPC architecture is an example of a RISC (Reduced Instruction Set Computing) architecture. As a result: All PowerPCs (including 64-bit implementations) use fixed-length 32-bit instructions. The PowerPC processing model is to retrieve data from memory, manipulate it in registers, then store it back to
The PowerPC has 32 general purpose registers, each either 32 bits or 64 bits in size (depending on which chip you're using). It should be of note that 32-bit PowerPC and 64-bit PowerPC really have the same instruction set, and 32-bit code will run natively unmodified on a 64-bit chip. 32-bit code is 64-bit code. Of course
crD can be omitted. In that case, the assembler assumes cr0. • The L field means “Long" (64-bit compare) if set to “1", or 32-bit compare if set to “0". On 32-bit PowerPC, L should always be set to “0". Because of this, a simplified mnemonic exists for all. “cmp"-series instructions: “cmpw crD, rA, rB" is equivalent to. “cmp crD,0
Note that these descriptions are taken from the 64-bit version of the instruction set; bit numbering are different for some instructions on 32-bit implementations. The lab course software uses a 32-bit PowerPC emulator. The mnemonics column shows all valid forms of an instruction; it also shows simplified mnemonics in italics
Oct 3, 2006 The POWER5 processor is a 64-bit workhorse used in a variety of settings. Starting with this introduction to assembly language concepts and the PowerPC instruction set, this series of articles introduces assembly language in general and specifically assembly language programming for the POWER5.
Jan 7, 2009 To specify an arbitrary 32-bit address, two instructions must be used, since all instructions are 32 bits long and can't contain both an opcode and a full address. A pair of instructions used to load or store data at an address falls into one of a small set of idioms, using the assembler operators lo16() , hi16()
