| Abstract: | Embedded system communicates with the peripherals using USB interface. In order to improve the efficiency and performance of data processing, in this paper the buffer structure of data transfer in USB interface of embedded system has been investigated. From the features of USB data transfer, a single-storage-based buffer structure is proposed to implement the seamless interface between USB modular and system which simultaneously saves the hardware resources. The implementation on FPGA platform has suggested that the proposed scheme is effective and feasible for data transfer in the embedded systems. |
