AN48864 discusses West Bridge® Turbo-MTP, which is a West Bridge specific implementation of Microsoft® Media Transfer Protocol (MTP). Mobile handsets and portable media devices seek compliance with MTP to transfer digital media from a Windows PC and to synchronize digital media files between the device and the PC. The West Bridge Turbo-MTP implementation provides significant performance improvements over the traditional MTP implementation.

Introduction

The West Bridge® Antioch™ and Astoria™ devices are peripheral controllers that support High-Speed USB and mass storage access. These controllers provide direct access from both a processor interface and a High-Speed USB interface to peripherals such as SDHC (SD 2.0), eMMC (MMC 4.2), CE-ATA, SDIO, and SLC NAND. These capabilities make West Bridge devices an optimal bridge solution for handset devices such as cell phones and portable media devices, by providing the fastest possible sideloading speeds, multitasking, and support for the latest multimedia and storage interfaces.
