—With the advent of new video standards such as MPEG-4 part-10 and H.264/H.26L, demands for advanced video coding, particularly in the area of variable block size video motion estimation (VBSME), are increasing. In this paper, we propose a new one-dimensional (1-D) very large-scale integration architecture for full-search VBSME (FSVBSME). The VBS sum of(More)
With the advent of new video standards such as MPEG-4 part-10 and H.264/H.26L, demands for advanced video coding (AVC), particularly in area of variable block searching motion estimation (VBSME), are increasing. This has led to research into suitable flexible hardware architectures to perform the various types of VBSME. In this paper, we propose a new 1-D(More)
New, generic silicon architectures for implementing Montgomery's multiplication algorithm are presented. These use Carry Save Adders (CSAs) to perform the large word length additions required by this algorithm when used for RSA encryption and decryption. It is shown that using a four-to-two CSA with two extra registers rather than a five-to-two CSA leads to(More)
Real-time matrix inversion is a key enabling technology in multiple-input multiple-output (MIMO) communications systems, such as 802.11n. To date, however, no matrix inversion implementation has been devised which supports real-time operation for these standards. In this paper, we overcome this barrier by presenting a novel matrix inversion algorithm which(More)
Absfruct-A systematic design methodology is described for the rapid derivation of %SI architectures for implementing high performance recursive digital filters, particularly ones based on most significant digit (msd) first arithmetic. The method has been derived by undertaking theoretical investigations of msd first multiply-accumulate algorithm and by(More)
