Instruction Execution Timing
10.3 CACHE AND ATC PERFORMANCE DEGRADATION TIMES
This section defines degradation times to MC68060 processor performance for cache and
ATC miss conditions (as detailed in 10.2 Timing Assumptions , the performance numbers
in 10.1.5 Dispatch Test 5: No Register Conflicts on sOEP.AGU Resources and 10.1.6
Dispatch Test 6: No Register Conflicts on sOEP.IEE Resources assume internal cache
hits for all memory accesses). If a cache miss is encountered, the appropriate delay times
defined in this section are to be used with the instruction times defined in 10.1.5 Dispatch
Test 5: No Register Conflicts on sOEP.AGU Resources and 10.1.6 Dispatch Test 6: No
Register Conflicts on sOEP.IEE Resources to determine MC68060 execution time.
10.3.1 Instruction ATC Miss
Assumptions:
Instruction ATC Miss = 10+3*w(3/0), if U-bit of descriptor is already set.
Instruction ATC Miss = 18+5*w(4/1), if U-bit of descriptor must be set by the MC68060.
