The aim of this thesis was to create a parameterisable Fast Walsh-Hadamard Transform in the form of a robust intellectual property core. This paper provides background information on the Walsh-Hadamard Transform (WHT), reprogrammable hardware and the current state of the intellectual property (IP) industry. The functionality of the IP core that was produced is explained, and further areas for study are explored. Customisable features of the transform include the number of points, the input word length, and the ordering. It is noted that the parameterisable FWHT core is consistent with IP principles, in that it is technology independent, customisable, and synthesizable.
