【Abstract】 In the design of MEDIWS real-time image processing system, we need to deal with so many common techniques such as the storage design,timing processing,A/D interface at a super high-rate and device driver program design in Windows98.We could smartly control A/D chip AD9057 with a timer circuit designed in a new way.Therefore, the frame storage with IDT71024 could work stably at a high rate. It is characterized by a low cost and an extensive application.更多还原
