Instruction Execution Timing
10.15 FPU INSTRUCTION EXECUTION TIMES
Table 10-25 shows the number of clock cycles required for execution of the floating-point
instructions, including completion of the operation and storing of the result. The number of
operand read and write cycles is shown in parentheses (r/w).

For these entries, add the effective address calculation time.
For the CPUSH instruction, the operand write figure refers to line-sized transfers.
