Error -Tolerant Digital Signal Processing
… the problem of reliable and energy-efficient digital signal processing (DSP) systems. We present a general framework for deep submicron (DSM) noise/soft error-tolerance and provide its energy-distortion analysis. We introduce a novel algorithmic noise tolerance (ANT) technique referred to as …

Low-Power Reconfigurable Digital Signal Processing
We present a design methodology for low-power communication systems. This is based on the concept of DAT and intellectual property (IP) core generators. Energy-optimum parameters are obtained via DAT, and are fed into IP core generators, which generate a synthesizable VHDL description of the IP …

Optimizing Vector Instruction Selection for Digital Signal Processing
Digital signal processing applications benefit from fast implementations of vectorized inner kernels. Existing compilers rely on brittle pattern-matching or search-based methods with poor scalability for vector instruction selection – techniques which are limited by a reliance on the syntax of the …

Signal Encoding and Digital Signal Processing in Continuous Time
This work investigates signal encoding in, and architectures of, digital signal processing systems that function in continuous time (CT). Unlike conventional digital signal processors (DSPs), which rely on a clock to dictate the sampling times of an analog-to-digital converter (ADC) and to provide …

Power Estimation and Minimization of Digital Signal Processing Systems
We have so far focussed on power dissipation in static CMOS circuits. Dynamic logic circuits are used in high-performance circuits due to their speed and area advantage over static CMOS circuits. In this thesis, we also present an optimization technique, termed clock-generating (CG) domino, for …

Finite state machine representation of digital signal processing systems
A new method for implementing digital filters is discussed. The met11od maximises the output signal to noise ratio of a filter by assigning at each of the filter variables an optimal quantization law. A filter optimised for a gaussian process is considered in detail. An error model is developed and …

An environment for the development of digital signal processing software
Prior to about 1980, real-time signal processing development work was dominated by hardware design time; each new algorithm required special hardware if it were to run in real time. The introduction of high-speed general-purpose digital signal processors has changed all that. Since these signal …
