Hexagon is VLIW DSP architecture designed by Qualcomm. It is used in many Qualcomm's SoC as Audio, Sensor or Compute coprocessor, and in the many Qualcomm modems. Usually runs some kind of Real-time OS, optimized for low power and small chip area. Supports of simultaneous execution of several threads, with interleaved multithreading in V1-V4 and dynamic multithreading since V5.
