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
The lwz instruction (load word and zero) loads a word (32-bit value), and if we are using 64-bit registers, zeroes out the highest 32 bits. The main function at this point is hopefully largely obvious, with the exception of the lis and ori functions. Since PowerPC instructions (even on 64-bit PowerPCs) are all 32 bits in length,
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 The mnemonics column shows all valid forms of an instruction; it also shows simplified mnemonics in italics. lwz, lwz, Load Word and Zero.

Description. The stw and st instructions store a word from general-purpose register (GPR) RS into a word of storage addressed by the effective address (EA). If GPR RA is not 0, the EA is the sum of the contents of GPR RA and D, a 16-bit signed two's complement integer sign-extended to 32 bits. If GPR RA is 0, then the EA
Like x86, PowerPC machine code consists of bytes, with addresses, that represent assembly instructions and operands. There's a separate instruction named "addi" (add immediate) to add a constant; plain "add" only works on registers. Memory is accessed with the "lwz" (load word) and "stw" (store word) instructions.
Movia is a pseudo statement, that loads a 32-bit immediate address to a register. As the instruction width in NIOS is fixed to 32-bit it happens using two instructions: "load_high_16_bits_and_clear_the_lower_part, register, #imm16_hi" "or_register_with_16_bit_immediate_at_the_lower_part, register,
Store Instructions Store Word (stw). Store Word (stw) Note The assembler destroys the contents of temporary registers $at, $t9, $t10, and $t11 for this instruction unless the .arch directive or the /arch command-line option causes the assembler to generate a single machine instruction in response to the stw command.
