Motor Control using DSC

[AnweshaPanda]

Hello, 

Is there any performance benchmarking data available of the DSCs against MCUs ? Can we combine the DSCs with i.MXRT/MCXA for motor control solution. 

The idea is to control a pmsm with absolute encoders via GaN inverters. The GaN requires sub-nano second PWM resolution that only DSCs are capable to handle within NXP product lines, but they lack abs encoder peripherals.

Hence wanted to know whether it's possible to do sw decoding of abs enc along with motor control on DSC or is it possible use DSC for PWM generation and Motor control task being carried out by a faster MCU?

Your question is missing the most important detail.
What is the absolute encoder interface and how fast it has to be ?

If it's an analog signal you just have to evaluate if the onboard ADCs are good enough (in precision and accuracy) and fast enough (samples/sec) or if you need an external ADC connected over SPI (for example). Plus don't forget to evaluate if the raw signal needs some analog or digital filtering to be clean enough.

If it's bit-parallel you just map it to GPIO's that can be read from a single I/O register
(DSC's GPIO ports have different mappings, ensure to select an hardware configuration with enough ports with only I/O not dedicated to other functions).

If it's over a serial link or over fieldbus it depends on the specific chip hardware and software support.
