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 …

Systematic hybrid analog/digital signal coding
This thesis develops low-latency, low-complexity signal processing solutions for systematic source coding, or source coding with side information at the decoder. We consider an analog source signal transmitted through a hybrid channel that is the composition of two channels: a noisy analog channel …

Signal Breaker: Fuzzing Digital Signal Processors
… application, fuzzing has yet to make its way to Digital Signal Processor (DSP) software. DSPs sit at the border between hardware and software systems: they transform analog signals external to a system into digital signals for internal processing. Many important societal applications including …

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 …
