Lut optimization for memory based computation

  1. 1. LUT Optimization for Memory-Based Computation By N.Tharun Kumar S.Vijay CH.John Williams Guided By: Tara Sai Kumar
  2. 2. Objective: To design LUT optimization for memory based computation. Design of APC-OMS combined LUT design for the multiplication of W-bit fixed coefficient A with 5-bit input X.
  3. 3. Abstract: We have APC and OMS techniques for lookup table . These techniques reduce LUT size by a factor two. The modified APC and OMS ,combine approach provides reduction in LUT size to one by fourth of conventional.
  4. 4. Introduction: LUT optimization is a technique used in: Digital Signal Processing Multiplication and Data Selection Process. It is used to decrease size and the memory required with the LUT without degrading its performance.
  5. 5. APC for LUT Optimization Modified OMS for LUT Optimization
  6. 6. Conventional LUT-based multiplier
  7. 7. Tools Xilinx VHDL
  8. 8. Proposed:  A different form of APC and combined that with a modified form of the OMS scheme for efficient memory based multiplication.
  9. 9. Block Diagram:
  10. 10. Benefits APC and OMS techniques reduce LUT by a factor of 2. Size of LUT is reduced to one by fourth of the conventional. For 16-bit and 32-bit word sizes, respectively, it offers more than 30% and 50% of saving in area-delay product over the corresponding CSD multipliers.
