Özet
Discrete cosine transform (DCT) is an integral part of many image compression standards. Image compression with HEVC inra prediction method also uses DCT. Because the complexity of DCT is high, the complexity of the encoder hardware is high and the energy consumption of the encoder is also high. In this study, a new approximated DCT architecture is proposed to reduce the complexity and energy consumption of DCT hardware used in image compression by high efficiency video coding (HEVC) intra prediction method. This architecture is based on the use of shift and add operation instead of multiplication, and the use of approximate 5:3 compressor chains for addition operations..
