What is the Opcode? What is the Operand? What is the value in Register 5 after the instruction is executed?

Expert Solution

Opcode and Operands are the terms used while talking about instructions running by CPU.

They form the instruction set of the microprocessor.

Opcode stands for Operation Code,it is a single instruction executed by CPU.

Opcode tells the CPU what to do, with the data besides it, the data that is to be processed.

Opcode is designed while the manufacturing of the chip, and opcode can't be changed untill you change the hardware.

While Operands are the variable that store data.

Eg: MOV A,B

here MOV is a opcode, meaninf move the data

A and B are variables, and this instruction means move data of B into A.

Opcode is the one which tells the ALU that what operation is to be performed between the data.

example: ADD R1,R2

ADD is the Opcode and R1 and R2 are the Operand .

i)In a computer, an instruction is composed of two fields: the opcode and an operand address. what is the minimum size of your instruction in bits if an instruction set of 327 opcodes and an address space of 128 Mbytes is required? NB. Use 1 Mbyte = 2^20 bytes ii) Instead of hard-writing the units, the software is used to interpret and execute instructions in a general-purpose system. Is the statement true or false

True and False 1. The instruction register stores machine code for the instruction being executed. 2. Before a digital computer may execute an instruction, the instruction code must be fetched from memory. 3. A pointer is a binary code for data in the arithmetic logic unit. 4. Von Neumann computer architecture stores data and instruction codes in the same memory. 5. Complex instruction set computers have instructions with greater speed than those in reduced instruction set computers.

Suppose the opcode of an MIPS instruction is 12 in decimal, and the rest of the machine code is 23483DB in hexadecimal (from high-order bit to low-order bit). What is the instruction? When showing the registers, use names (e.g. $t0, $s2) instead of indices (e.g $8, $17). For branch instructions, show offset in place of label, e.g. beq $t1, $t2, 92.

Assume that for a given program 70% of the executed instruction are arithmetic, 10% are load/store, and 20% are branch. i. Given the instruction mix and the assumption that an arithmetic instruction requires 2 cycles, a load/store instruction takes 6 cycles, and a branch instruction takes 3 cycles, ?nd the average CPI. ii. For a 25% improvement in performance, how many cycles, on average, may an arithmetic instruction take if load/store and branch instructions are not improved at all.
