Motion Estimation (ME) is the most critical and complex part of any video codec system. The different algorithms and their architectures are proposed for ME process. In this paper, we have proposed an efficient architecture for Hexagon Based Search (HexBS) algorithm and implemented on XC4VSX25 Virtex4 FPGA. Simulation results show that the proposed architecture is capable of calculating the Motion...
Algorithms and architectures for performing modular multiplication operations are important in residue number system and cryptography. In this paper a new algorithm of Radix-4 MSB modular multiplier using 4–2 compressor is presented. The recoding rules for the radix-4 Booth's algorithm are used to reduce the number of partial products and improve the total hardware area and time. This new algorithm...
