Hardware Oversampling Specification Format
Selects which method is used to specify the hardware oversampling rate. This value directly affects the level of parallelism of the core implementation and resources used. When Maximum Possible is selected, the core uses the maximum oversampling given the sample period of the signal connected to the Data field of the s_axis_data_tdata port. When Hardware Oversampling Rate is selected, you can specify the oversampling rate. When Sample Period is selected, the core clock is connected to the system clock, and the value specified for the Sample Period parameter sets the input sample rate the core supports. The Sample Period parameter also determines the hardware oversampling rate of the core. When Sample Period is selected, the core is forced to use the s_axis_data_tvalid control port. See Decimator, for more details on the core control ports.
Sample Period
Specifies the input sample period supported by the core.
Hardware Oversampling Rate
Specifies the hardware oversampling rate applied to the core.
