CCS/TMS320F28379D: Stop the pipeline of CLA in TMS320F28379D micro controller

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

Respected sir/madam,

I am using TMS320F28379D for generating a sine wave of 50khz using GPIO port A using an array. It successfully generates the sine wave, but the problem is when an array have same points it just skip the repeated array by using pipeline of Control Law Accelerator (CLA). Is there any way to stop the pipeline process ? If there is a way to stop the pipeline process please explain me in brief.

Akshay,

Unfortunately I'm not sure I understand the problem you are having. Can you elaborate? It works under some conditions but not others specifically with the CLA?. Have you tried to debug the CLA code by stepping through it?

The pipeline can cause problems with read-modify-write operations to a single location. My understanding is this is a copy operation. Please let me know if that is not the case.

If you are trying to modulate the duty of a square wave, you may want to consider using a PWM module to generate the waveform.

Here are a couple of related posts which may help:
