Running models on Hexagon DSP need a few prerequisites for DSP developers:
* You need make sure SOCs of your phone is manufactured by Qualcomm and has HVX supported.
* You need a phone that disables secure boot (once enabled, cannot be reversed, so you probably can only get that type phones from manufacturers)
* You need sign your phone by using testsig provided by Qualcomm. (Download Qualcomm Hexagon SDK first, plugin your phone to PC, run scripts/testsig.py)
* You need install Hexagon nnlib backend by following nnlib README (https://github.com/XiaoMi/nnlib).
Then, there you go. You can run Mace on Hexagon DSP.
