CCS/TMS320F28035: Parallel Processing in C2000 controllers.

Hello,

Thanks for your question! For the particular C2000 device you mentioned, there is a built-in control law accelerator (CLA) for certain math functions that can be run in parallel with the main C28x CPU. I have provided a few links below that can provide a good idea of how the CLA can be used in a variety of applications, as well as implementation examples that can potentially be directly used in your particular application:

Software Examples to Showcase Unique Capabilities of TI’s C2000™ CLA

Sensorless Field Oriented Control of 3-Phase Induction Motors Using Control Law Accelerator (CLA)

Digital Control of Two Phase Interleaved PFC and Motor Drive Using MCU With CLA

This can help your execution time by significantly offloading part or all of the calculations in the ISR to the CLA.

For other C2000 devices, a configurable logic block (CLB) can also be run in parallel with the main C28x CPU, which can potentially further offload processing from the main CPU and speed up execution time. Additionally, some C2000 devices have implemented a floating point unit (FPU) directly into the C28x core, along with a VCU (Viterbi, Complex Math and CRC Unit), and TMU (Trigonometric Math Unit) to further reduce the cycles needed to run certain functions.
