Instr fetch unit
NettetInstruction Fetch Units and Instruction Queues • Most processors employ sophisticated fetch units that fetch instructions before they are needed and store them in a queue. • The fetch unit also has the ability to recognize branch instructions and to generate the target address. Thus, penalty produced by unconditional NettetFirst of all, the control unit will decode the Opcode and Func field and set the control signals ALUctr and RegWr accordingly. We will cover this later. While this is happening (points to Control Delay), we will also be reading …
