The replay operation is designed to deal with the effects of the memory system on instruction timing. Instructions are statically scheduled in the D3 stage based on a prediction of when the source operand will be available. Any stall from the memory system can result in the minimum of an 8-cycle delay. This 8-cycle delay minimum is balanced with the minimum number of possible cycles to receive data from the L2 cache in the case of an L1 load miss. Table 14.2 gives the most common cases that can result in an instruction replay because of a memory system stall.
