Images are transferred to the FPGA board via a high speed USB2.0 channel, implemented with a standard macrocell. A LabVIEW host application controlling a frame grabber and an industrial camera is used to capture and exchange video data with the hardware co-processor. The FPGA accelerator is based on a Altera Cyclone II chip and is implemented as a system-ona- programmable-chip (SOPC) with the help of an embedded Nios II software processor. The SOPC system integrates the processor, external and on chip memory, the communication channel and a typical image filter appropriate for the evaluation of the system performance. Measured transfer rates over the communication channel and processing times for the implemented hardware filters are presented for various frame sizes. A range of applications is also discussed.enAttribution-NonCommercial-NoDerivatives 4.0 ΔιεθνέςAttribution-NonCommercial-NoDerivatives 4.0 Διεθνέςhttp://creativecommons.org/licenses/by-nc-nd/4.0/http://creativecommons.org/licenses/by-nc-nd/4.0/Άρθρο σε επιστημονικό συνέδριοHardware designImage ProcessingFPGAsEmbedded Processors
