Performance Graph

Notes

• Running average load (window length is 8 sec) is calculated for all cores.(Running average* : Series of averages is calculated for a fixed window period of different subsets of the full data set and final average is calculate from the average series)
• Open source software Oprofile is used to measured the A8 thread details, Oprofile thread add some additional A8 load

Summary

• ARM A8 load is reduced by 17 %, Video processor load is reduced by 6% and VPSS load is reduced by 13.5% wrt to earlier EZSDK 05.02.01.59 release metrics
• VENC component took the maximum Video media controller load (32 MHz), and VFPC-DEI component took the maximum load in VPSS media controller (37 MHz).
• H.264 Frame chunking thread took the maximum load on A8 processor ( 110 MHz)
• The encoded video quality is good without artifacts.
