LUT Optimization forMemory-Based ComputationByN.Tharun KumarS.VijayCH.John WilliamsGuided By:Tara Sai Kumar
Objective:To design LUT optimization for memory basedcomputation.Design of APC-OMS combined LUT design forthe multiplication of W-bit fixed coefficient Awith 5-bit input X.
Abstract:We have APC and OMS techniques for lookuptable .These techniques reduce LUT size by a factortwo.The modified APC and OMS ,combineapproach provides reduction in LUT size toone by fourth of conventional.
Introduction:LUT optimization is a technique used in:Digital Signal ProcessingMultiplication and Data Selection Process.It is used to decrease size and the memoryrequired with the LUT without degrading itsperformance.
APC for LUT OptimizationModified OMS for LUT Optimization
BenefitsAPC and OMS techniques reduce LUT by afactor of 2.Size of LUT is reduced to one by fourth of theconventional.For 16-bit and 32-bit word sizes, respectively,it offers more than 30% and 50% of saving inarea-delay product over the correspondingCSD multipliers.
