For LL modules it is very straightforward - all LL modules are called one by one in every LL pipeline tick, so module's period is always equal to LL pipeline period For DP modules a period has different meaning. As DP is called "on demand" - whenever it is ready, it may not be scheduled at every LL tick (and usually is not) A period meaning for DP is "a time when the module must finish its job and provide data to next module in pipeline or the data flow will be corrupted (a glitch)" In common case the period is calculation is based on module's OBS - if module provides OBS bytes of data in each cycle, it MUST finish at least before the next module drains the buffer In some special cases - modules producing a variable bitrate (like MPEG) or not producing audio data at all (phrase detector, speech recognition, etc.) - the module may set the period itself during prepare operation This commit adds calculation of DP period. This value will be used in following commit as a base for deadlines calculation in EDF Signed-off-by: Marcin Szkudlinski <marcin.szkudlinski@intel.com>
