Implementation of SoC-PC Communication Interface Based on USB2.0

USB is more used than some traditional inter-PC Bus such as PCI and ISA due to the high speed and agility and also provides properly convenient communication interface for some A/D conversion, FPGA of the external logic device. This passage uses the asynchronies work mode of slave FIFO and adopts HDL to compose state machine for FPGA to produce some control signals which implements data acquisition for the solution of high speed and reliability communication between SoC and PC. The results of the final experiment show that this scheme is very fast and efficient for the data acquisition and it can also apply other cases such as video acquisition for the embedded system through USB.
