Preload reference area to an intermediate buffer in sub-pixel motion search In sub-pixel motion search, the search range is small(+/- 3 pixels). Preload whole search area from reference buffer into a 32-byte aligned buffer. Then in search, load reference data from this buffer instead. This keeps data in cache, and reduces the crossing cache- line penalty. For tulip clip, tests on Intel Core2 Quad machine(linux) showed encoder speed improvement: 3.4% at --rt --cpu-used =-4 2.8% at --rt --cpu-used =-3 2.3% at --rt --cpu-used =-2 2.2% at --rt --cpu-used =-1 Test on Atom notebook showed only 1.1% speed improvement(speed=-4). Test on Xeon machine also showed less improvement, since unaligned data access latency is greatly reduced in newer cores. Next, I will apply similar idea to other 2 sub-pixel search functions for encoding speed > 4. Make this change exclusively for x86 platforms. Change-Id: Ia7bb9f56169eac0f01009fe2b2f2ab5b61d2eb2f

Preload reference area to an intermediate buffer in sub-pixel motion search In sub-pixel motion search, the search range is small(+/- 3 pixels). Preload whole search area from reference buffer into a 32-byte aligned buffer. Then in search, load reference data from this buffer instead. This keeps data in cache, and reduces the crossing cache- line penalty. For tulip clip, tests on Intel Core2 Quad machine(linux) showed encoder speed improvement: 3.4% at --rt --cpu-used =-4 2.8% at --rt --cpu-used =-3 2.3% at --rt --cpu-used =-2 2.2% at --rt --cpu-used =-1 Test on Atom notebook showed only 1.1% speed improvement(speed=-4). Test on Xeon machine also showed less improvement, since unaligned data access latency is greatly reduced in newer cores. Next, I will apply similar idea to other 2 sub-pixel search functions for encoding speed > 4. Make this change exclusively for x86 platforms. Change-Id: Ia7bb9f56169eac0f01009fe2b2f2ab5b61d2eb2f

STACK_FRAME_DESTROY_X4
Preload reference area to an intermediate buffer in sub-pixel motion search In sub-pixel motion search, the search range is small(+/- 3 pixels). Preload whole search area from reference buffer into a 32-byte aligned buffer. Then in search, load reference data from this buffer instead. This keeps data in cache, and reduces the crossing cache- line penalty. For tulip clip, tests on Intel Core2 Quad machine(linux) showed encoder speed improvement: 3.4% at --rt --cpu-used =-4 2.8% at --rt --cpu-used =-3 2.3% at --rt --cpu-used =-2 2.2% at --rt --cpu-used =-1 Test on Atom notebook showed only 1.1% speed improvement(speed=-4). Test on Xeon machine also showed less improvement, since unaligned data access latency is greatly reduced in newer cores. Next, I will apply similar idea to other 2 sub-pixel search functions for encoding speed > 4. Make this change exclusively for x86 platforms. Change-Id: Ia7bb9f56169eac0f01009fe2b2f2ab5b61d2eb2f
