Architecture using dedicated endpoints and protocol for creating a multi-application interface and improving bandwidth over universal serial bus |
摘要 |
A USB function device (14) for coupling to a USB host (12). The USB function device (14) comprises circuitry (32) for providing a capability to the USB host, where the circuitry for providing a capability comprises an address space (VBUS). The USB function device (14) further comprises a USB interface circuit (30) coupled between the USB host and the circuitry for providing a capability to the USB host. The USB interface circuit (30) comprises a memory area (44, 106) comprising a write endpoint (1062) accessible to the USB host for writing a plurality of bytes to the memory area via the write endpoint. The plurality of bytes comprise data information and protocol information. The write endpoint comprises an endpoint-type other than a control-type endpoint. The USB interface circuit also comprises circuitry for decoding (166) the protocol information and circuitry for communicating the data information to the address space in response to the protocol information.
