Abstract
Disclosed is an adaptive interface circuit for connecting a USB interface and a PCIe interface. The adaptive interface circuit includes a UAS protocol processing circuit, a data buffer, and an NVMe protocol processing circuit. The UAS protocol processing circuit receives a UAS command from a host via the USB interface and transmits a write-ready signal to the host according to the UAS command so that the host transmits host data to the data buffer according to the write-ready signal; the UAS protocol processing circuit also provides the UAS command to the NVMe protocol processing circuit. The NVMe protocol processing circuit generates X NVMe command(s) according to the UAS command; afterwards the NVMe protocol processing circuit starts transmitting X doorbell signal(s) to a storage device via the PCIe interface so as to let the storage device retrieve the host data from the data buffer according to the X NVMe command(s).
