Abstract	In order to fulfill the new ISO 14649 (STEP-NC), Computer Numeric Control (CNC) machines need to support high computational demand algorithms. This fact is one of the main barriers for the adoption of the STEP-NC standard for CNC machines. Hardware acceleration is an incremental solution that can be cleanly added to these systems while keeping everything else intact. The cost is much lower and the development time is much shorter than replacing the computers by faster ones. In this paper a design space exploration for the implementation of a common CNC algorithm is presented. It shows different hardware solutions, as well as the performance, cost and precision trade-offs. The hardware has been implemented with Xilinx FPGAs and coded with a high level hardware description language (Handel-C). The execution time is two orders of magnitude faster than legacy CNC systems and one order of magnitude faster than modern PCs.
