A Comparison of Different Fixed Width Multipliers Based On MLCP

Rima N, Nisha R


Abstract: The fixed-width multiplier is attractive to many multimedia and digital signal processing systems which are desirable to maintain a fixed format and allow a little accuracy loss to output data. This brief includes a comparative study of different fixed-width Booth multipliers- PT (most accurate fixed width multiplier) and DT (least area requirement) fixed width multipliers with the Proposed accuracy-adjustment fixed-width Booth multipliers that compensates the truncation error using a multilevel conditional probability (MLCP) estimator. To consider the trade-off between accuracy and area cost, the MLCP provides varying column information to adjust the accuracy with respect to system requirements. Unlike previous conditional-probability methods, the proposed MLCP uses entire nonzero code, namely MLCP, to estimate the truncation error and achieve higher accuracy levels. And a comparative study of different fixed width multipliers based on MLCP using different fast adders such as carry look ahead adder, Kogge-stone adder etc are also included. The design was modeled using Verilog, simulated and synthesized using Xilinx ISE 14.7


Keywords: Direct truncated DT, multi -level conditional probability MLCP, Post truncated PT
