Section 7 Pipeline Operation
4. When an STS.L (memory) instruction is located immediately after a MULS.W instruction
Rev. 5.00 Jun 30, 2004 page 470 of 512
REJ09B0171-0500O
When the contents of a MAC register are loaded from memory using an STS instruction, an
MA stage for accessing the multiplier and writing to memory is added to the STS instruction,
as described later. When the MA of the STS instruction contends with the operating multiplier
(mm), the MA is extended until one cycle after the mm ends (the M—A shown in the dotted
line box in figure 7.59) to create a single slot. The MA of the STS contends with the IF. Figure
7.59 illustrates how this occurs, assuming MA and IF contention.
