This work presents an efficient implementation of a softcore multiplier, i.e., a multiplier architecture which can be efficiently mapped to the slice resources of modern Xilinx FPGAs. Instead of dividing the multiplication into the generation of partial products and the summation using a compressor tree, as done in modern multipliers, an array-like architecture is proposed. Each row of the array generates...
In this paper we describe an efficient implementation of an IEEE 754 single precision floating point multiplier targeted for Xilinx Virtex-5 FPGA. VHDL is used to implement a technology-independent pipelined design. The multiplier implementation handles the overflow and underflow cases. Rounding is not implemented to give more precision when using the multiplier in a Multiply and Accumulate (MAC)...
Interpolation is a basic concept in all fields of science and technology. Calculating the neighboring weights of an un interpolated data is found. This can be done effectively by partial volume interpolation, because it produces smooth changes with small changes in transformation and improves subvoxel accuracy. Partial volume interpolator consists of multipliers as its main component. In this work,...
In this paper, we proposed the compact construction of a matched filter for integrand code, which do not require the high-rate clock pulse in two-valued PWM (pulse width modulation) code, using a real-valued shift-orthogonal finite-length sequence, which has a sharp a periodic autocorrelation function with zero sidelobes except at left and right shift-ends. This matched filters is implemented on a...
