Question

What is the type, assembly language instruction, and binary representation of the instruction described by the following MIPS fields: op = 0x23, rs = 1, rt = 2, const = 0x4?

Answer 1

The instruction described by the given MIPS fields is a load word instruction.

Step-by-step explanation:

The instruction described by the given MIPS fields is a load word instruction. The assembly language instruction for this is lw.

The binary representation of this instruction is obtained by converting the opcode (op) field and the register fields (rs, rt) into binary, and combining them with the constant field (const).

For the given fields:

• op = 0x23, which is 100011 in binary.
• rs = 1, which is $at (assembler temporary) register.
• rt = 2, which is $v0 (first return value) register.
• const = 0x4, which is 0000000000000100 in binary.

Combining these values, the binary representation of the instruction is:

100011 00001 00010 0000000000000100
