A NAVEL ROUNDING BASED APPROXIMATE MULTIPLIER FOR HIGH SPEED MAC UNIT DESIGN

  • Unique Paper ID: 170376
  • PageNo: 378-383
  • Abstract:
  • In this paper we propose a advanced rounding based approximate multiplier (AROBA) which is highly accurate than the conventional multiplier (ROBA). The main concept of multiplier depends on rounding of numbers. This multiplier is applicable for both signed and unsigned numbers. The hardware consists of three major blocks, one block is for unsigned and two blocks are for signed operations. The accuracy of the multiplier is compared with the conventional rounding based approximate multiplier (which are in 2n) where the advanced rounding based approximate multiplier gives an exact output for the given inputs (irrespective of 2n) and parameters such as area, power delay, pass rates are been calculated and compared with conventional multiplier where, AROBA gives better results and with the AROBA MAC unit is implemented.
