WebMay 31, 2015 · Delay slots are not limited to jumps. On some architectures, data hazards in CPU pipeline are not resolved automatically. This means that after each instruction which modifies a register there is a slot where the new value of the register is not accessible yet. If the next instruction needs that value, the slot should be occupied by a NOP: WebThe pipelined processor takes the same control signals as the single-cycle processor and therefore uses the same control unit. The control unit examines the opcode and funct fields of the instruction in the Decode stage to produce the control signals, as was described in Section 7.3.2. These control signals must be pipelined along with the data ...
