| Abstract: | The high speed data transmission system is introduced for the collection and storage of infrared images from medium-wave infrared thermal imager in real-time based on the core processor FPGA. The system consists mainly of USB firmware program,FPGA control program and PC software. High speed data transmission on USB interface is accomplished by the control of on-chip FIFO in the USB2. 0 CY7C68013 A working in Slave FIFO mode.The experimental results indicate that the system is high in speed and accurate in transmission. |
