Design of a configurable accelerator for moment computation

摘要

The method of moments is one of the most powerful techniques fornimage analysis. However, real-time applications of this method have beennprohibited due to the computational intensity in calculating thenmoments. This paper presents a novel configurable hardware acceleratornfor expediting the moment computation. The fundamental building block ofnthe proposed accelerator is a custom-designed floating-point momentnprocessing element (MPE). Running at 75 MHz, the MPE can provide a 12Xnspeedup over a 166 MHz TMS320C6701 digital signal processor. On top ofnthis, a linear performance boost can be obtained by connecting up toneight MPEs into a one-dimensional (1-D) array
