Multipartite Tables in JBits for the Evaluation of Functions on FPGAs

This paper presents the implementation, on Virtex FPGAs, of a core generator for arbitrary numeric functions in fixed-point format. The cores use the state-of-theart multipartite table method, which allows input and output precisions in the range of 8 to 24 bits on current Virtex chips. The implementation uses the JBits API to embed elaborate optimisation techniques in the description of the hardware.
