TDA2: image rotated function , how to optimize and improve efficiency?

Hi @yuling ma ,

do you use an algorithm, you wrote yourself? You can check if the following documents can help you:

Introduction to TMS320C6000 DSP Optimization:

Optimizing Loops on the C66x DSP:

Hand-Tuning Loops and Control Code on the TMS320C6000:
