| Abstract: | The signal processing method using in optoelectronic color sorter was introduced.The system core is FPGA.The system uses only a FPGA,but accomplishes 256 points signal processing.It achieves low cost but high performance.It makes fully use of FPGA system resources.It uses the FPGA has multi-function input and output to make LVDS signal inputs directly.It uses the FPGA′s logic element to count,compare and control globally.The system uses the multiplier in FPGA to accomplish amplifying function.It makes use of the memory in FPGA to accomplish pulse wide and delaying time function. |
