Reconfigurable computing devices such as FPGAs offer application developers the ability to create solutions with a performance comparable to that of a hardware solution, but with the flexibility of software. Development tools that attempt to support popular software development languages such as C and Java have been developed to reduce the need for the FPGA… (More)
Classification of documents by genre is typically done either using linguistic analysis or term frequency based techniques. The former provides better classification accuracy than the latter but at the cost of two orders of magnitude more computation time. While term frequency analysis requires much less computational resources than linguistic analysis,it… (More)
Matrix multiplication is a basic computing operation. Whereas it is basic, it is also very expensive with a straight forward technique of O(N 3) run-time complexity. More complex solutions such as Strassen's algorithm exist that reduce this complexity to O(N log 2 7); the recursive nature of such algorithms place a large burden on memory systems due to… (More)
Recursive solutions are effective software techniques that are difficult to map into hardware due to their dependency on input size and data values. As a result, most high-level design tools do not allow for recursive calls. In this paper we present a technique for mapping the merge-sort algorithm, as a case study, into a reconfigurable system. Our mapping… (More)
This paper gives an overview of a mobile device question answering application that has recently been developed in the CSIRO ICT Centre. The application makes use of data in an open-domain encyclopaedia to answer general knowledge questions. The paper presents the techniques used, results and error analysis on the project.
