MIPS registers use for procedures. $a0-$a3 argument registers to pass parameters. $v0-$v1 value registers to return values. $ra return address register to return

av K Marklund · 2005 — I den inledande kommentaren anges att indata skall ges i register $a0 och att utdata ges i register $v0. Sedan f rs ker vi med jr $ra igen och vi hamnar i en o ndlig loop. I MIPS-assembler kan dessa operation skrivas:.

$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. jal Fact MIPS är ett skyddssystem för hjärnan – konstruerat för att ge extra skydd.
