In this paper, we investigate the design and implementation of standard and fixed-width 8 x 8 multipliers using row bypassing technique. The design is described using VERILOG Hardware Descriptive Language and implemented using XILINX ISE 12.1v tool. Multipliers are a core part of any data path circuit and in many multimedia applications; we require both inputs and outputs to have the same bit width. For these type of applications the standard multipliers is not the best choice because an n-bit input will produce a 2n-bit output. An n-bit output i.e., a fixed width multiplier can be obtained by truncating the least significant partial products of the multiplier. The comparison table shows that a significant reduction of FPGA resources and delay can be achieved using fixed-width multipliers instead of standard multipliers.
