- Abstract
- We proposed an efficient VLSI hardware architecture of the High Efficiency Video Coding (HEVC) using a hybrid embedded compression algorithm for reducing the frame memory bandwidth. This architecture was designed to reduce the memory bandwidth using an adaptive prediction lossy/lossless algorithm. We saved about 50% of the memory access cycles for the reference data compared to a previous algorithm. The PSNR degradation of 0.12 dB on average was proposed algorithm at the compression ratio of 50%. The architecture was implemented in Verilog HDL and synthesized using a Synopsys Design Compiler with a 65nm cell library; the gate count was about 25,000 gates.
