全新 Turbo-MTP™ 功能可加速媒体传输协议以改进侧载(Side Loading)性能并提高用户体验

本文引用地址: SAN JOSE, Calif., February 12, 2009 –Cypress Semiconductor Corp. (NYSE: CY) today introduced a new module for its West Bridge® peripheral controllers that offers the fastest available transfer of multimedia files from a PC to handheld device via the widely-used Media Transfer Protocol (MTP). Cypress's Turbo-MTP™ solution enables users to sideload a feature-length movie in less than a minute – 10x faster than competing MTP implementations. 2009年2月12日,北京讯,日前,赛普拉斯半导体公司 (NYSE: CY) 宣布推出 West Bridge® 外设控制器的一个全新模块,通过广泛采用的媒体传输协议 (MTP),可实现目前 PC 到手持设备间最快的多媒体文件传输速度。赛普拉斯 Turbo-MTP™ 解决方案能让用户在不到一分钟的时间内将一部故事片电影侧载 (sideload) 到手机上,这比竞争性 MTP 实施方案快了10 倍。

The Turbo-MTP solution dramatically increases the effectiveness of MTP, a USB-based protocol used by Rhapsody, Napster, Verizon V CAST and other online video and music services. MTP enables the transfer of metadata such as song titles, images, and Digital Rights Management (DRM) information. With MTP, a handheld retains access to storage even while plugged into a PC – users can still make a phone call or watch videos while connected, instead of facing a “PC Connect” frozen screen. MTP also removes any risks of file corruption when users unplug their handheld during a file transfer. Natively supported in Windows Media Player (WMP), MTP protocol enables direct, drag-and-drop synchronization between WMP and a handheld. Turbo-MTP 解决方案大幅提高了 MTP 的效率。MTP 是 Rhapsody、Napster、Verizon V CAST和其他在线视频和音乐服务所采用的基于USB的协议,能传输歌曲名称、图像和数字版权管理 (DRM) 信息等元数据。利用 MTP,手持设备在与 PC 连接时也能继续对存储器进行访问、拨打电话或观看视频,而不会出现“PC 连接”时的屏幕冻结问题。MTP 还消除了用户在文件传输过程中断开连接后导致文件破坏的风险。MTP 协议由Windows Media Player (WMP)支持,能在 WMP 和手持设备之间直接通过拖放方式实现同步。

“MTP has greatly improved the user experience from competing protocols, but it slows down transfer speeds,” said Alakesh Chetia, Vice President of the West Bridge Business Unit at Cypress. “Turbo-MTP dramatically accelerates sideloading for MTP handhelds, offloading the data stream from the main processor onto a high-performance, USB-optimized West Bridge controller. As a result, users gain the benefits of MTP without a transfer penalty.” 赛普拉斯West Bridge业务部副总裁 Alakesh Chetia 指出:“MTP相对于竞争协议而言大幅改善了用户体验,但这会降低传输速度。Turbo-MTP 大幅提高了 MTP 手持设备的侧载速度,将主处理器从数据流传输工作中解放出来,而让高性能USB优化型West Bridge控制器来完成传输工作,这样,用户既能从MTP中受益,同时传输速度又不会受到影响。”

Cypress will demonstrate the Turbo-MTP solution at Mobile World Congress in Barcelona on February 16 to 19 in Hall 1, Booth 1H35. Recent benchmarks showed that a top-tier multimedia phone using Turbo-MTP transferred files 10 times faster than other MTP phones. 赛普拉斯将在 2 月 16 日至 19 日于巴塞罗那 (Barcelona) 举办的全球移动大会 (Mobile World Congress) 1 号展厅 1H35 号展台上演示 Turbo-MTP 解决方案。近期进行的基准测试显示,采用 Turbo-MTP 技术的名牌多媒体手机传输文件的速度是其他 MTP 手机的 10 倍。

Enhanced by West Bridge solutions – including the Antioch™ and Astoria™ peripheral controllers – MTP represents a significant improvement over the legacy Mass Storage Class (MSC) protocol. Using MSC, users could not access any content on their handset when connected to a PC. MTP maintains simultaneous access to storage, so users can still fully use their phone or PMP while connected. Also, with MSC, users were required to use specific “Safe Removal” operations before unplugging the USB cable or have all stored files get corrupted. MTP is immune to this loss of data. MTP通过采用包括 Antioch™ 和 Astoria™ 外设控制器在内的 West Bridge 增强型解决方案,相对于传统的 Mass Storage Class (MSC) 协议而言实现了显著改善。如果使用 MSC,用户就不能访问与 PC 相连接的手机上的任何内容。而 MTP 则能保持对存储空间的同时访问,这样用户就还能在连接的同时完全使用电话或 PMP。此外,如果使用 MSC,用户在拔下 USB 电缆前必须在电脑上进行“安全删除硬件”操作,否则就有可能导致所有存储文件遭到破坏。而 MTP 完全没有这种数据丢失的危险。

The West Bridge Antioch controller achieves superior data transfer performance by providing a direct path from high-speed USB 2.0 to handset storage devices such as Secure Digital High Capacity (SDHC), MultiMedia Card (MMC), Hard Disk Drive (HDD) and NAND Flash. By fully offloading management of USB and storage from the main baseband processor, the controller saves critical processor resources and allows a mobile handset to maintain full functionality while simultaneously sideloading multimedia files, synchronizing PIM data, or even using the phone as a PC modem. The West Bridge Astoria controller adds to this performance with a configurable multimedia storage interface and flexible processor interface, easing connections to a broad range of embedded processors and mass storage devices. These features allow the Astoria controller to connect to any embedded processor or DSP, bringing MLC NAND support to new applications including portable media players (PMPs), wireless cards, dongles, portable navigation devices (PNDs), digital cameras, POS terminals and more. West Bridge Antioch 控制器通过提供一条从高速 USB 2.0 到手机存储设备(如高容量安全数字卡 (SDHC)、多媒体卡 (MMC)、硬盘驱动器 (HDD) 和 NAND 闪存等)的直接路径,取得了卓越的数据传输性能。由于主基带处理器完全从 USB 和存储管理任务中解放了出来,该控制器因此能节约宝贵的处理器资源,并能让移动手持设备在侧载多媒体文件、同步 PIM 数据、甚至将电话用作 PC 调制解调器的同时保持其所有功能。West Bridge Astoria 控制器还在上述性能的基础上添加了可配置的多媒体存储接口和灵活的处理器接口,从而简化了与多种嵌入式处理器和大容量存储设备的连接。上述特性可使 Astoria 控制器连接到任何嵌入式处理器或 DSP,为便携式媒体播放器 (PMP)、无线网卡、收发器、便携式导航设备 (PND)、数码相机、POS 终端等各种新型应用提供 MLC NAND 支持。

关于 West Bridge 系列 Devices in the new West Bridge family of peripheral controllers function as a companion chip to an embedded central processing unit (CPU) to free it from data-intensive operations. In the same way the North Bridge and South Bridge were introduced in the PC architecture to enable the main CPU to evolve independently from quickly changing memory and peripheral interfaces, embedded systems are evolving towards a similar architecture, where a West Bridge device manages the interfaces and offloads from the main CPU specific peripheral-to-peripheral traffic. 全新 West Bridge 系列外设控制器中的器件作为嵌入式中央处理器 (CPU) 的辅助芯片发挥作用,以便将 CPU 从数据密集型操作中解放出来。就像 PC 架构中引入北桥 (North Bridge) 和南桥 (South Bridge) 芯片以便让主 CPU 从快速变化的存储器和外设接口中独立出来一样,嵌入式系统也在朝着类似的架构方向发展,以便让 West Bridge 器件来管理接口,将 CPU 从具体的外设间通信中解放出来。

The West Bridge family is based on Cypress’s Simultaneous Link to Independent Multimedia™ (SLIM™) architecture, which manages multiple, dedicated paths between peripherals, memory and the processor to allow maximum data throughput. In addition to providing a path to interfaces not supported by the main processor, the SLIM architecture allow direct and independent data transfer from one interface to another, offloading the main CPU, and freeing up its resources for higher system performance.
