Detailed explanation-1: -During the decode stage, the control unit (CU) will decode the instruction in the CIR. The CU then sends signals to other components within the CPU, such as the arithmetic logic unit (ALU) and the floating point unit (FPU).
Detailed explanation-2: -Ans : The instruction cycle consists of four phases: fetching an instruction from memory, decoding the fetched instruction, reading the address from memory, and finally, instruction execution.
Detailed explanation-3: -Decode stage The decoding process allows the CPU to determine what instruction is to be performed so that the CPU can tell how many operands it needs to fetch in order to perform the instruction. The opcode fetched from the memory is decoded for the next steps and moved to the appropriate registers.
Detailed explanation-4: -ALU stands for Arithmetic and Logical Unit which performs Arithmetic functions like Addition, subtraction, division, etc. CU stands for control unit which performs the task of controlling functions of the computer. It monitors and gives proper instructions to all parts of the computer.
