Title: The development of an application specific processor for the transmission line matrix method

Abstract: This thesis details the development of an application specific processor for the transmission line matrix (TLM) method. The application of TLM to the modelling of wave propagation in two and three dimensions is introduced with the discussion focusing on the concept of computational efficiency. Methods for improving computational efficiency are reviewed, in particular the implementation of TLM on large scale parallel computers. It is shown that these methods, while increasing throughput, make inefficient use of available resources. The review of existing methods is used to define a set of goals for a new class of application specific TLM processor. The development of an application specific processor based upon the two dimensional shunt node is presented. This gives rise to an efficient, bit serial scatter processor. The implementation of this processor within a complete, application specific TLM system is discussed. The system is based around a unique mapping of the TLM connect routine to hardware. The bit serial scatter processor is modified to allow the modelling of inhomogenous and three dimensional media using the stub loaded shunt node, the symmetrical condensed node and the symmetrical super condensed node TLM schemes. It is shown that all four TLM schemes may be implemented within a single architecture without the introduction of redundant elements through the use of reconfigurable logic. The implications of interfacing this system to a host PC using the PCI bus are discussed. The processor designs are reviewed within the context of the goals set for the work. It is shown that all of the goals were successfully met. The implications and limitations of the processor are discussed. The thesis concludes with recommendations for areas worthy of further study.
