This paper presents a novelapproach to design Flexible computational unit(FCU) exploiting carry save arithmetic anddadda multiplier. Earlier projects emphasized ondesigning systems with low power and fastoperations resulting in increased area. The goalof this project is to design DSP system to makethe design more efficient by proposing Daddatree multiplier. Utilizing Dadda tree multiplierreduces the area required for the advisement. Asin these modern times, most of the electronicsystems are adapted to perform digital signalprocessing; the DSP integrated systems havewide range of applications. Kernel which is thecore of the DSP system consists of data flowgraph that features the corresponding arithmeticoperation performed by the system. These DFGsbasically consist of arithmetic units such asadders, multipliers etc that are mapped onto theproposed flexible control units which are carrysave formatted data. As we know that the basicintension of designing integrated circuits is tominimize the dimensions of a given circuit. Thisobjective is achieved by incorporating dada multiplier as multiplier unit of the DSP dataflow graph template. This implementationshows considerable difference in terms of areawhich further leads to other advantages such asto fabricate more number of components ontothe resulted area.
