Abstract :
In this paper, we present a comparison between two methods, the modified Loeffler algorithm (11 MUL and 29 ADD) and distributed arithmetic, to implement the DCT/IDCT algorithm for MPEG or H.26x video compression using VHDL description language. The implementation has been achieved on Altera Stratix EP1S10 FPGA which provides a dedicated DSP blocks required for common signal processing functions. A new solution based on this DSP blocks used to implement multipliers for the modified Loeffler algorithm in order to optimize speed and area
