The Hexagon SDK is used for building code to run on DSP processors. Use of the Hexagon toolchain to offload ECC verify operations has been added to wolfSSL. This can free up the main CPU for other operations or lead to future optimizations with HVX on some algorithms that use vector operations. The Makefile for building with the Hexagon toolchain and a README with more information can be found in the directory wolfssl-4.4.0/IDE/HEXAGON.
