5.7 Write Sequences

8-Word Write Sequence


An 8-word write sequence writes back a dirty block from the primary data cache to the secondary cache.

Figure 5-8 depicts a secondary cache 8-word write sequence. SC(A,B)DWay are driven with the way bit obtained from the primary data cache tag. The secondary cache tag is not written since it was previously updated when the primary data cache block was modified.
