Configuration

`DSP Core` — DSP core for processing
`Core-0` (default) | `Core-0` to `Core-17`

Select the DSP core from the list of supported cores.

Timestamp

`Timestamp frequency scaling` — Frequency scaling for the ADC frequency
`/4` (default) | `/8` | `/16` | `/32`

Specify the division factor for the clock frequency used in the ADC.

Dependencies

To enable this parameter, select the Enable timestamp output parameter in the CDSP block in the Simulink model.

`Gate source to trigger timestamp` — Hardware trigger source
`GTM - ATOM0` (default) | `GTM - TOM#` | `GTM - ATOM#` | `EGTM - TOM#` | `EGTM - ATOM#`

Specify the source of the gate signal to trigger the timestamp.

Note

You must configure the appropriate trigger from the PWM block with a rate (1/initial clock frequency of PWM) that is greater than the conversion time of the filtered data output. Calculate this conversion time as |Size of filtered data x clock cycles / F_ADC|. For the filter chain FC0 with analog to digital conversion frequency (F_ADC) of 160 MHz, 128 filter taps, and a decimation rate of 1, it requires 249 clock cycles to output correct filtered data.
