TDM FIR can be configured to operate in SSR Mode using TP_SSR
template parameter. The mode will create an array of TP_SSR
kernels and create the TP_SSR
amount of the input and output ports.
When SSR mode is use, i.e. when TP_SSR > 1
, Input Samples, and therefore, corresponding TDM Channels will be split over multiple parallel paths.
As a result, each SSR path will operate on a fraction of the workload, i.e. each path will operate on TP_TDM_CHANNELS / TP_SSR
number of TDM Channels.
Input data samples are distributed across the input paths in a round-robin, sample-by-sample mechanism where each input path processes a fraction of the input samples, i.e. TP_INPUT_WINDOW_VSIZE / TP_SSR
. More details in: Super Sample Rate - Sample to Port Mapping.
