We speculated that when an instruction is read from memory, it could be passed im- mediately to the control The IR has two parts: 1. IR (opcode) The most significant bits of the instruction make up the opcode. . note that the program counter can be incremented at the same clock tick as loading the instruction register.
registers correspond to register A and register B, we also sign extend the. 15 LSB to get, along with the PC the Immediate value. JAL: Since the JAL is a branch instruction in the third cycle we save the PC+4 held in ALUOut to register 31. This require a small modification to the datapath: we need to have 31 as an input to the
Decodes instruction to determine what segments will be active in the datapath. • Generates signals to. – Set muxes to correct input. – Operation code to ALU. – Read and write to register file. – Read and write to memory (load/store). – Update of program counter (branches). – Branch target address computation. • Two parts:
Instruction memory. Instruction address. Instruction a. Instruction memory b. Program counter. Add Sum c. Adder. ALU control. RegWrite. Registers. Write register REG 1. REG 2. BEQ/BNE/J. BRANCH ADDRESS. OFFSET. 31. 26 25. 21 20. 16 15. 11 10. 6 5. 0. REG 1. REG 2. SW. STORE ADDRESS. OFFSET. 31. 26 25.
control hazard. – deciding on control action depends on previous instruction dt10 2011 12.2. Structural hazards. • conflict for use of a resource. • in MIPS pipeline with a single memory. – load/store requires data access. – instruction fetch: stall for that cycle causing a pipeline “bubble". • hence pipelined datapaths require.

Next let's look at the case that the current instruction is a conditional branch, for example, bne. This instruction is more interesting because the PC
