The mechanisms receive, in a first single instruction multiple data (SIMD) vector register of the data processing system, CABAC encoded data of a bit stream. The CABAC encoded data includes a value to be decoded and bit stream state information. The mechanisms receive, in a second SIMD vector register of the data processing system, CABAC decoder context information. The mechanisms process the value, the bit stream state information, and the CABAC decoder context information in a non-recursive manner to generate a decoded value, updated bit stream state information, and updated CABAC decoder context information. The mechanisms store, in a third SIMD vector register, a result vector that combines the decoded value, updated bit stream state information, and updated CABAC decoder context information. The mechanisms use the decoded value to generate a video output on the data processing system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Arithmetic decoding acceleration","description":"Mechanisms for performing decoding of context-adaptive binary arithmetic coding (CABAC) encoded data.
