CDSP Peripheral Configuration

Map CDSP peripherals in the model to peripheral registers in the MCU

Since R2024a

Description

View and edit the map of peripherals in the Infineon^® AURIX™ model to the hardware peripherals.

Using the Hardware Mapping tool, you can:

• View and edit configuration parameters for CDSP peripheral block.

• Check for any conflicts between the peripherals.

In the Hardware tab of the Simulink^® mode, click Hardware Mapping.

Parameters

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.

Dependencies

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

Hardware Trigger — Hardware trigger for timestamp

Adc_TriggerSignal_0 (default) | Adc_TriggerSignal_1 | Adc_TriggerSignal_2 | Adc_TriggerSignal_3

Specify the hardware trigger for the timestamp.

Dependencies

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

Trigger edge — Hardware trigger edge for timestamp

Rising-edge (default) | Disable | Falling-edge | Both-edge

Select the type of hardware trigger edge to trigger the timestamp.

Dependencies

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

Trigger delay in ns (0:65535) — Gate trigger delay for timestamp

0 (default) | scalar in the range (0, 65535)

Specify the gate trigger delay for the timestamp.

Dependencies

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

Boundary

Lower limit in volts (-5V to 5V) — Lower limit for the boundary band

0 (default) | scalar in the range (-5, 5)

Set the lower limit of the boundary band to check the result.

Upper limit in volts (-5V to 5V) — Upper limit for the boundary band

5 (default) | scalar in the range (-5, 5)

Set the upper limit of the boundary band to check the result.

Enable hysteresis on boundary flag — Option to enable hysteresis on boundary flag

off (default) | on

Enable hysteresis to avoid metastable states and switching due to internal ground bounce.

Boundary mode — Activate boundary flag based on boundary band limits

Disabled (default) | Exceeds upper limit | Lower than lower limit | Out of bound

Activate boundary flag based on the boundary band limits.

Dependencies

To enable this parameter, disable the Enable hysteresis on boundary flag parameter.

Service request — Service request based on the boundary mode

None (default) | Inside boundary band | Outside boundary band | Out of bound

Service request based on the boundary mode.

Integrator Control

Window gate source — Hardware trigger source for integration window

GTM-ATOM0 (default) | GTM-ATOM# | GTM-TOM#
