Suppose a computer has 16-bit instructions. The instruction set consists of 32 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register, and the second must be memory. Expanding opcodes are not used. The machine has 16 registers.

We can determine the three machine language instructions. Figure 2.6 summarized the portion of MIPS machine language in this section FIGURE 2.6 MIPS architecture revealed through Section 2.5. The two MIPS instruction formats so far are R and I. The first 16 bits are the same: both contain an op field, giving the base operation; an rs operations. Every computer has its own unique instruction set. The ability to store and execute instructions, the stored program concept, is the most important property of a general-purpose computer. An instruction code is a group of bits that instruct the computer to perform a specific operation.

4/15/2009 · Best Answer: Assuming all opcodes are the same length, you will need 8 bits to hold the operation. 2^7 is 128, which is not enough to select one of 150 operations. Since each instruction is stored in one 24-bit word, and an opcode is 8 bits, that leaves 16 bits left for the address part. Since we address 24-bit words (3 bytes) and have 16-bit addresses, we can address 3*2^16 bytes, or 192KB. Assume a CPU has the following instruction format: op_code mode1 operand1 [mode2 operand2] [mode3 operand3] Instructions use 1-3 operands. Each operand has its own mode specifier. The CPU’s instruction set has 61 operations (op codes) and there are 6 different addressing modes available. Assume a fixed length 32-bit instruction.
