Current Projects

SCAMP CameraSCAMP-5: This device is the latest in the family of our pixel-per processor vision chips using analogue processing elements. The chip can execute many image processing algorithms in real-time with minimal power consumption. The smart camera systems based on the chip are currently used in a number of projects in our lab and in the labs of our collaborators in the UK and overseas. The sensor/processor integration and massively parallel operation provide a low-cost, low-power, high-performance intelligent vision systems for robotics, surveillance, machine vision, biomedical applications and research on algorithms for cellular processor arrays. Please see the SCAMP Vision Sensor webpage for more information.
 

Completed Projects

 
FINE3D (Fine-Grain Processor Arrays in 3D Silicon Technologies) project, funded by the EPSRC, investigated the design of cellular processor arrays for next-generation silicon technologies, where many device layers can be integrated in a single device. Wafer stacking and massive interconnect achieved using through-silicon-vias provides both opportunities and design challenges. We researched processor architectures that make best use of the available intra-layer bandwidth, investigated partitioning of the processing circuitry amongst silicon layers, and looked into heterogenous architectures where different layers are fabricated using different technologies, most suitable for individual system components. In particular, we are interested in fine-grain processor arrays, which we believe provide architectural solution that can fully exploit the benefits offered by the 3D integration.
 
REVERB (Reverse Engineering the Vertebrate Brain). This project was a multidisciplinary collaboration between a number of universities (Manchester, Sheffield, Aberystwyth, Bristol, Dundee) investigating integrative computation for autonomous agents, based on action-selection architecture of the basal ganglia. We were implementing low-level image processing required for this project, as well as some neural models, using SCAMP-3 and SCAMP-4 chips. We were also working towards an FPGA-based accelerator for neural computation, to tackle the real-time embedded implementation on an autonomous robot. We developed the APRON (Array Programming Environment) software, as a front-end to the accelerator. The software is also an efficient simulation tool on its own, furthermore it provides a basis for platform-independent array processor interface, programming language, and code compiler, and has been adopted to work with SCAMP and ASPA chips. See REVERB project webpage for details.
 
COLAMN (Computing Architecture Based on Laminar Microcircuitry of the Neocortex). This project was a collaboration between neurobiologists, computational neuroscientists and VLSI engineers (Manchester, Plymouth, Cambridge, Oxford) aiming at understanding the way cortical circuits process information, and ultimately providing ideas for building brain-inspired microelectronic circuits. We have developed an analogue silicon neuron, which efficiently implements biologically plausible spiking behaviour of cortical neurons. Currently we are investigating higher-level cognitive models of the cortex, and their VLSI implementation. more...
 
Cellular Asynchronous Arrays: This project investigates design of vision chips and fine-grain processor arrays based on novel control schemes, where individual processors are triggered as data is available at their neighbours, optimising speed and power consumption of the devices. The aim is to provide image processing engines suitable for both low-level, pixel-based operations (filtering, feature detection etc.) as well as more global, object-based algorithms, such as object reconstruction, skeletonisation, watarshed transform, distance transform etc. The ASPA chip contains a SIMD processor array, operating in mixed bit-serial/bit-parallel mode, as well as a wave-propagating network. The work continues on next generation of the ASPA processor in the Fine-Grain 3D project. more...
