2.1 C7x DSP Benchmark

This section describes the benchmarks of the C7x DSP using kernels which are critical in the DSP algorithms. The C7x libs, such as FFTLIB and DSPLIB, are used for the benchmarks. These libraries contain optimized functions for most common used operations, such as finite impulse filter and dot product. These libraries are included in the FREERTOS-SDK of AM62D, distributed in source form. Instructions for building and running the modules are included in the documentation folder of each library.

The performance results presented for C7x DSP are all executed on bare-metal with warm L2 cache. Refer to Section 1.1 for information about loading and running bare-metal binaries on AM62D EVM. The benchmarks in the following subsections are organized based on the C7x libs containing them.
