Implementation of a Program Address Generator in a DSP Processor
The purpose of this study is to construct a “Program Address Generator”(PAG) to a 24-bit Harvard type, RISC DSP processor using the VHDL language. The PAG is a part of the Continue reading
Analysis of Fixpoint Aspects for Wireless Infrastructure Systems
A large amount of today’s telecommunication consists of mobile and short distance wireless applications, where the effect of the channel is unknown and changing over time, and thus needs Continue reading
Digital Guitar Effects Unit and Amplifier
ABSTRACT
This report outlines the design and implementation of a digital guitar effects unit and amplifier. The main portion of this project consisted of the digital equalizer and effects. Several commercial equalizers were researched in order to decide the typical Continue reading
A Novel Approach for High Speed and Low Power 4-Bit Multiplier
A circuit design for a new high speed and Low Power 4-bit Braun Multiplier is presented. The multiplier is implemented by using different power reduction techniques. To design a Continue reading
Implementation Considerations for Active Noise Control in Ventilation Systems
The most common method to attenuate noise in ventilation systems today is passive silencers. For these to efficiently attenuate frequencies below 400 Hz such silencers need to be large and a more neat solution to Continue reading
Low Power and Low Complexity Shift-and-Add Based Computations
The main issue in this project is to minimize the energy consumption per operation for the arithmetic parts of DSP circuits, such as digital filters. More specific, the focus is on single- and multiple-constant multiplications, which are realized using Continue reading
Low Power Shift and Add Multiplier Design
Today every circuit has to face the power consumption issue for both portable device aiming at large battery life and high end circuits avoiding cooling packages and reliability issues that are too complex. It is generally accepted that during Continue reading
