The accumulated access time for a single MUNICH32 channel, depending on the actual
frame size, is then related to the serial transfer time on a PCM system:
(3 + size)
The following two diagrams illustrate the overall results for two different ranges and their
corresponding resolution. As you can see, for frame size greater than 32 bytes the time
needed for MUNICH32 memory accesses drops below 5%. That means in a simple
communication subsystem (e.g. Primary Access Board) the CPU performance is also
reduced by 5% only and it is therefore not necessary to use a complex multiport memory
approach to reach a significant overall performance gain.
