The Opus codec test suite has 14 test cases, such as CELT, SILK, Opus_api, Opus_decode, Opus_encode, padding, project test cases ref RFC 6716, and so on. All these standard test cases are executed on the PolarFire SoC Icicle kit with the throughput of 99%.

The following figure shows the Opus codec test suite summary for PolarFire SoC Icicle Kit.
