Figure 11: main tasks used in the application
The samples coming from the ADC are captured by task “SMT391_ADC” which
outputs four samples at a time at ¼ of the sampling frequency. The samples for
each ADC channel are output output on a separate port of the task.
Task “Pack32to64” groups the samples eight by eight. This grouping enables the
tasks connected afterwards to use a clock twice slower.
The data are then duplicated.
