Performance Data
The PM856 and PM860 processor units have the same internal design. They differ
only in performance when executing an application program.
Using the same application program in PM856 and PM860, the difference in
execution time can be expressed as:
Execution time in PM856 = 2 *Execution time in PM860
Example: If a certain application program has an execution time of 100 ms in
PM860, the same application program will have an execution time of 200 ms in
PM856.
