Integrated circuits fabricated in deep sub-micron technology are vulnerable to intermittent or transient faults which are the predominant cause of system failures. With continued scaling, operating voltage levels have reduced and resultant decrease in noise margins, the possibility of transient faults is likely to increase. Also, during operation in adverse environments, transient faults occur upon...

Efficient motion estimation is an important problem because it determines the compression efficiency and complexity of a video encoder. Motion estimation can be formulated as an optimization problem. This paper starts with an introduction of basic motion estimation problem and discusses issues specific to video motion estimation of two types FSBME & VSBME estimations. This paper in three sections...

Today's modern mobile communications require minimum bandwidth, minimum loss, delay and better transmission of speech. This paved a way for the development of speech codec with low bit rates among which CELP codec inherit the merits of both waveform and source codec. The most time consuming and computational intensive process in modern speech codec is algebraic code book search (ACS). The 30% of process...
