What does load Word do in MIPS?
Similarly one may ask, what does load address do in MIPS?
— The address operand specifies a signed constant and a register. — These values are added to generate the effective address. The MIPS ?load byte? instruction lb transfers one byte of data from main memory to a register. The ?store byte? instruction sb transfers the lowest byte of data from a register into main memory.
Likewise, what is a word in MIPS? A word generally means the number of bits that can be transferred at one time on the data bus, and stored in a register. In the case of MIPS, a word is 32 bits, that is, 4 bytes. Words are always stored in consecutive bytes, starting with an address that is divisible by 4.
Simply so, how does store word work in MIPS?
How does the Store Word(SW) and Load Word(LW) instructions work, MIPS. SW performs the operation MEM[$s + offset] = $t, but in the data-path it looks like they have performed the operation MEM[Data($s)+ offset] = $t , because instead of taking the value $s as an input into the ALU it took in the data stored in $s.
How do you use lb in MIPS?
The lb instruction loads a byte from memory and sign extends to the size of the register. The lbu instruction does the same without sign extension (unsigned). In two's complement the most significant bit can be used to determine the sign of the number, a '1' means it is negative, and a '0' means it is positive.
