17.2 Sample program execution rate comparison
Sample program execution rates are compared in this paragraph.
The execution time ratio depends on the program or the usage conditions.
Table 17.2.1 Sample program execution time ratio (external data bus width and software Wait)
Calculation value : The value is calculated from the shortest execution cycle number of each instruction
Calculation value
External
17.2.1 Difference depending on data bus width and software Wait
Internal areas are always accessed at 16-bit data bus width and without software Wait. In the external
areas, the external data bus width and software Wait are selectable. Table 17.2.1 lists the sample program
(refer to Figure 17.2.1) execution time ratio depending on these selection and used memory areas.
