Registers. MIPS I has thirty-two 32-bit general-purpose registers (GPR). Register $0 is hardwired to zero and writes to it are discarded. $31 $ra return address MIPS Architecture Registers The MIPS processor has 32 general-purpose registers, plus one for the program counter (called PC) and two for the results of the multiplication and division operations, called HI and LO, for the high 32 bits and the low 32 bits of the answer. MIPS uses the jump-and-link instruction jal to call functions. —The jal saves the return address (the address of the next instruction) in the dedicated register $ra, before jumping to the function. —jal is the only MIPS instruction that can access the value of the program counter, so it can store the return address PC+4 in $ra.

PROSPEKT - Finansinspektionen

MIPS machine language is designed to be easy to decode. —Each MIPS instruction is the same length, 32 bits. —There are only three different instruction formats, which are very similar to each other. Studying MIPS machine language will also reveal some restrictions in the instruction set architecture, and how they can be overcome. MIPS is a register-to-register, or load/store, architecture.
