Analysis of HEVC transform throughput requirements for hardware implementations

作者：

Highlights：

•

• Typical throughput assumptions about the transform submodule are overly optimistic.

• A Complexity Index is proposed to evaluate actual throughput requirements.

• A detailed HEVC–AVC comparison focused on transform throughput is presented.

• The impact of each coding tool on transform throughput is assessed.

• A practical case study involving a hardware transform module is presented.
