2023.2 English

Vitis Codec Library is an open-sourced library written in HLS C/C++ for the acceleration of image processing. It aims to provides reference designs for image codec algorithms that fit the Xilinx Alveo Series acceleration cards. The APIs in Vitis Codec Library have been classified into two layers, namely L1/L2. Each targets to serve different audience.

  • L1 APIs locate at Vitis_Libraries/codec/L1. They are basic components that will be used to compose compute-units. The L1 APIs are all well-optimized HLS designs and are able to fit into various resource constraints.
  • L2 APIs locate at Vitis_Libraries/codec/L2. They are a number of compute-unit designs running on Alveo cards. It provides a set of compute-unit designs implemented in HLS codes. These L2 APIs needs to be compiled as OpenCL kernels and will be called by OpenCL APIs.
