This paper presents a novel motion and disparity estimation (ME, DE) scheme in Multiview Video Coding (MVC) that addresses the high throughput challenge jointly at the algorithm and hardware levels. Our scheme is composed of a fast ME/DE algorithm and a multi-level pipelined parallel hardware architecture. The proposed fast ME/DE algorithm exploits the correlation available in the 3D-neighborhood...
This work proposes an VHDL generation software for optimized FIR filters. In this paper a near optimum algorithm for constant coefficient FIR filters was used. This algorithm uses general coefficient representation for the optimal sharing of partial products in Multiple Constants Multiplications (MCM). The developed tool was compared to Matlab FDA toolbox. Synthesis results show that our tool is able...
This paper addresses constant coefficients parallel FIR filter optimizations. The optimizations proposed use a combination of two approaches: the reduction of the coefficients to a limited number of power-of-two (PT) terms, where the maximum number of non-zero bits is set as a constraint, followed by common sub-expression elimination (CSE) among multipliers. Implementation results and the optimization...
