This paper reports on the results of a study to accelerate string tokenization using FPGAs suitable for both IoT gateways and data center servers. The prototype developed with Xilinx High-Level Synthesis software runs at 200 MHz and processes up to 32 ASCII characters per clock cycle. It incorporates either OpenCL or our own framework (Volvox) to transfer data between a host computer and a FPGA board via a PCI Express interface. Evaluations showed processing with a prototype with Volvox was approximately 10 times faster than with a CPU.
