A new sorting control system in field programmable gate array (FPGA) - the core of control - was proposed because the previous one couldn't meet the requirements of the multi-channel and high yield. It focused on designs of both hardware circuit and FPGA programming module. In the system, the accurate lossless delay of multiple signals was applied by using of RAM and its control module in FPGA. The sorting signals were generated based on the parallel execution characteristics of FPGA program. Real-time communication was realized between CAN controller of SPI and human-computer interface. A large number of experiments were done to test the proposed system. Results showed that the sorting control system could process multi-channel and higher-yield signals significantly. And the materials sorter was improved both in detectable level and yield. © 2014 SERSC.
