Optimization of RealVideo deblocking filter based on SIMD technology for Loongson

How the debloking filter works in the process of RealVideo decoding is introduced. The filter’s complexity is analyzed and the filter is optimized by using the multimedia instruction on Loongson platform. The result show that the debloking filter in RealVideo decodinghas efficiently improved the image quality both in subjectivity and impersonality. With optimization ofthe multimedia instruction the filter resolved the time-consuming problem in filtering and enhanced the power of playing RealVideo files on Loongson platform.
