9.4 IMMEDIATE INSTRUCTION EXECUTION TIMES
The numbers of clock periods shown in Table 9-8 include the times to fetch immediate
operands, perform the operations, store the results, and read the next operation. The total
number of clock periods, the number of read cycles, and the number of write cycles are
shown in the previously described format. The number of clock periods, the number of
read cycles, and the number of write cycles, respectively, must be added to those of the
effective address calculation where indicated by a plus sign (+).
In Tables 9-8, the following notation applies:
9.5 SINGLE OPERAND INSTRUCTION EXECUTION TIMES
Tables 9-9, 9-10, and 9-11 list the timing data for the single operand instructions. The total
number of clock periods, the number of read cycles, and the number of write cycles are
shown in the previously described format. The number of clock periods, the number of
read cycles, and the number of write cycles, respectively, must be added to those of the
effective address calculation where indicated by a plus sign (+).
