Optimizing H.264 Software Codec on Intel Atom and Intel Core2 Processors Targeting Intel Digital Security Surveillance Applications
H.264/AVC is the latest video coding standard from ISO/IEC Moving Picture Experts Group (MPEG). Due to its high compression efficiency and superior video quality, H.264/AVC is becoming the most preferred and common video codec in DSS applications despite increasing encoding complexity. Intel Atom processors are low-power CPUs with Intel SSSE3 instruction sets and Intel Hyper-Threading Technology, making the product line ideal for cost-effective, embedded DSS applications. This paper proves H.264 encoding performance boost when utilizing processor specific Intel SSSE3 and SSSE4 instructions.
