Todman T, Luk W, 2001, Reconfigurable Designs for Ray Tracing, Pages: 300-301
We describe a feasibility study into using reconfigurable hardware for real-time ray tracing. The study includes mapping time-consuming parts of the algorithm into hardware, and transforming the algorithm following a breadth-first approach to improve system performance when the host bus is slow. We also examine the application of runtime reconfiguration, and estimate the reconfigurable resources required for animating complex scenes.

Zhang XJ, Ng KW, Luk W, 2000, A combined approach to high-level synthesis for dynamically reconfigurable systems, Pages: 361-370, ISSN: 0302-9743
In this paper, two complementary design models and related synthesis techniques are combined to capture behavioral and structural information in modelling and synthesizing a dynamically reconfigurable system. The proposed formulation is achieved by using finite domain constraints and related constraint-solving techniques offered by constraint logic programming. Our formulation represents operation-level temporal constraints and dynamic resource constraints in a unified model. Different synthesis tasks, such as temporal partitioning, scheduling and dynamic module allocation can be modelled in this framework, enabling the discovery of an optimal or near optimal solutions. Experiments have been carried out using a prototype of the high-level synthesis system implemented in CHIP, a constraint logic programming system. Current experimental results show that our approach can provide promising synthesis results in terms of the synthesis time and the number of reconfigurations.
Derbyshire A, Luk W, 2000, Combining serialisation and reconfiguration for FPGA designs, Pages: 636-645, ISSN: 0302-9743
This paper describes a tool framework and techniques for combining serialisation and reconfiguration to produce efficient designs. Convolver and matrix multiplier designs are examined. Several optimisation techniques, such as restructuring and pipeline morphing, are presented with an analysis of their impact on performance and resource usage. The proposed techniques do not require the basic processing element to be modified. An estimate of the performance of the serial designs is given when mapped using distributed arithmetic and constant multiplier cores onto a Xilinx Virtex FPGA.

Constantinides GA, Cheung PYK, Luk W, 1999, Truncation noise in fixed-point SFGs, Electronics Letters, Vol: 35, Pages: 2013-2014, ISSN: 0013-5194
A new model for predicting truncation error variance in fixed-point filter implementations is introduced. The proposed model is shown to be more accurate than existing models, particularly for some direct hardware implementations. In addition, some comments are made on the applicability of existing error models.
