The Filter Specification tab is used to define the basic filter configuration as in Filter Options in the Vivado IDE.
- 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_tdataport. 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 thes_axis_data_tvalidcontrol 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.
