WebHere is how this instruction is executed: The 32-bit address in $10 is: 0x00400000. The offset is sign-extended to 32 bits: 0x00000060. The memory address is the 32-bit sum of the above: 0x00400060. Main memory is asked for data from that address. After a one machine cycle delay the data reaches $8. $8 = The 4 bytes.
