An efficient floating-point multiplier for digital signal processors

An efficient floating-point multiplier for digital signal processors

The floating-point multiplication is one of the most basic and frequent digital signal processing operations, and its accuracy and throughput greatly decide the overall accuracy and throughput of the digital signal processors. Based on vectorizing a conventional double precision multiplier, we propose a multiple precision floating-point multiplier. It supports either one double precision multip...

Floating-to-Fixed-Point Conversion for Digital Signal Processors

Digital signal processing applications are specified with floating-point data types but they are usually implemented in embedded systems with fixed-point arithmetic to minimise cost and power consumption. Thus, methodologies which establish automatically the fixed-point specification are required to reduce the application time-to-market. In this paper, a new methodology for the floating-to-fixe...

Interval Arithmetic Multiplier for Digital Signal Processors

Interval methods offer quite new research aspects regarding Digital Signal Processing. In scenarios like finite numeric representation, limited precision sensors or the quantization process, signal processing has been practicing interval mathematics as quite a reliable gizmo for expressing the uncertainties. Some types of control systems like estimating or soft computing systems, the uncertaint...

A floating-point to integer C converter with shift reduction for fixed-point digital signal processors

A floating-point to integer C program translator is developed for convenient programming and efficient use of fixed-point programmable digital signal processors (DSP’s). It not only converts data types and supports automatic scaling, but also conducts shift optimization to enhance execution speed. Since the input and output of this translator are ANSI C compliant programs, it can be used for an...
