Instruction Execution Timing
10.16 EXCEPTION PROCESSING TIMES
Table 10-26 indicates the number of clock cycles required for exception processing. The
number of clock cycles includes the time spent in the OEP by the instruction causing the
exception, the stacking of the exception frame, the vector fetch, and the fetch of the first
instruction of the exception handler routine. The number of operand read and write cycles
is shown in parentheses (r/w).

FP Unimplemented Data Type
Indicates the time from when RSTI is negated until the first
instruction enters the OEP.
For these entries, add the effective address calculation time.
Assumes either autovector or external vector supplied with zero
For these entries, add the instruction execution time minus 1 if a
post-exception fault occurs.
