MOTOROLA
The next example is the data cache hit example from 11.4 EFFECT OF DATA
timing. The first is the timing from the appropriate table. The second is the
timing adjusted for a data cache hit. The third adds wait states only to write
T h e t h i r d
Using the general Equation (11-2), calculate as follows:
CACHE with two wait states per cycle (four-clock read/write). Hits in the data
cache and instruction cache are assumed. Three lines are shown for each
operat/ons, since the read operations hit in the cache and cause no delay.
