Abstract： |
The invention discloses a circuit interface for high speed charge coupled device (CCD) camera, belonging to the field of data transmission device, adopting USB2.0 as an interface between high speed CCD camera and computer, where the USB2.0 is connected with a CPLD (complex programmable logic device) as control sensor; the USB2.0 is connected with data/address bus of a MCU, and the I/O port of the CPLD is connected with DMA of the USB2.0 to implement high speed transmission between the CPLD and the USB2.0. In addition, a FIFO is extended from a USB2.0 interface chip, thus omitting a collection card, reducing the cost and enhancing the system reliability; besides, avoiding the data loss in the USB2.0-based transmitting course. |
