Programmable Numerical Function Generators for Two-Variable Functions
This paper proposes a design method and programmable architectures for numerical function generators (NFGs) of two-variable functions. To realize a two-variable function in hardware, we partition a given domain of the given function into segments, and approximate the function by a polynomial in each segment. This paper introduces two planar segmentation algorithms that efficiently partition a domain of a two-variable function. This paper also introduces two architectures that can realize a wide range of two-variable functions. Our architectures allow a systematic design of two-variable functions. FPGA implementation results show that, for a complicated function, our NFG achieves 58% of memory size and 39% of delay time of a circuit designed using one-variable NFGs.
