Abstract
B-spline curves can represent almost any smooth shape, being adopted by file exchange standards, used as a wavelet basis for multiresolution systems and manufacturing efficiency is increased using b-splines toolpaths. The respective algorithms for conventional CPUs demand great computational effort, requiring another hardware architectures, like GPUs, for better processing efficiency. This paper describes a system on a chip that generates b-splines curves from given control points in a concurrent way, based in a FPGA platform, including features that are not addressed by the few works in the area. This system is faster than a quadcore CPU in the order of the number of generated points, at the same clock rate. The independence of the number of generated and initial control points, and the processing determined by the FPGA capacity, makes it a better choice for embedded systems in relation to conventional CPUs.
