Section 7 Pipeline Operation
1. When a MAC.W instruction is located immediately after a MULS.W instruction
Rev. 5.00 Jun 30, 2004 page 466 of 512
REJ09B0171-0500O
When the second MA of a MAC.W instruction contends with the mm generated by a preceding
multiplication instruction, the bus cycle of that MA is extended until the mm ends (the M—A
shown in the dotted line box below) and that extended MA occupies one slot.
If one or more instructions not related to the multiplier comes between the MULS.W and
MAC.W instructions, multiplier contention between the MULS.W and MAC.W instructions
does not cause stalls (figure 7.55).
