Functional Overview
Turbo-MTP Support
Turbo-MTP is an implementation of Microsoft’s MTP enabled by West Bridge. In the current generation of MTP-enabled mobile phones, all protocol packets needs to be handled by the main processor. West Bridge Turbo-MTP switches these packet types and sends only control packets to the processor, while data payloads are written directly to mass storage, thereby bringing the high performance of West Bridge to MTP.
