I was learning about the cache prefetch engine in the Hexagon DSP. But while looking at the sobel example code given in the SDK, I couldn't find the use of any kind of L2 caching in the code. Whereas I did find the use of cache operations in the Downscaleby2 example. Does cache prefetching not happen at the software level in the sobel example or what am I missing exactly?
