Section 7 Pipeline Operation

When the contents of a MAC register are loaded from a general-purpose register using an LDS
instruction, an MA stage for accessing the multiplier is added to the LDS instruction, as
described later. When the MA of the LDS instruction contends with the operating multiplier
(mm), the MA is extended until the mm ends (the M—A shown in the dotted line box in figure
7.41) to create a single slot. The MA of this LDS contends with IF. Figure 7.41 illustrates how
this occurs, assuming MA and IF contention.
