Similarly, the immediate data are sign extended.ĮX: Execution/ Effective Address Calculation : ALU is used to perform some calculation. ID: Instruction Decode : The instruction already fetched in IF is decoded.ĭecoding is done in parallel with reading the register operands rs and rt, the two source registers. So PC is not updated in this stage the new value is stored in a register NPC. IF: Instruction Fetch : Here the instruction pointed to by the PC is fetched from the memory and also the next value of PC is computed.įor the branch instruction, the new value of PC may be the target address. We divide the instruction cycle into 5 steps: > HERE Offset = Number of Instructions we Need to go back +1 R- type, I-type and Jump-type (not included)
