Embedded Speech Processing System for Car Wireless Terminals
Computer Engineering, 2005Co-Authors: Liu RunshengAbstract:This paper introduces a novel embedded speech Processing system, which is implemented in car wireless terminals. This system is composed of two Modules: bluetooth Module and speech-Processing Module. Through the blue tooth Module, car wireless terminal can communicate with cellular phone, download the address book from cellular phone and send it to the speech Processing Module, while the speech Processing Module fulfills speech recognition, speech synthesis, speech coding and system controlling functions. This system can on-line generate the speech recognition network according to the address book and the recognizable vocabulary scale is up to 1000 words. When the address book includes 600 names, the recognition accuracy rate is more than 97%. The hardware platform of this system is based on SoC architecture and high integration of this architecture makes the system more robust.

High-speed data Processing Module for LLRF
IEEE Transactions on Nuclear Science, 2015Co-Authors: D. Makowski, A. Mielczarek, P. Perek, A. Napieralski, L. Butkowski, J. Branlard, M. Fenner, H. Schlarb, B. YangAbstract:Linear accelerators, like the Free-electron LASer in Hamburg (FLASH) or the European X-Ray Free Electron Laser (E-XFEL) take advantage of the digital Low Level Radio Frequency (LLRF) system to control the phase and amplitude of an electromagnetic field inside superconducting cavities. The real-time control LLRF system, Processing data within a few microseconds, has to fulfil performance requirements and provide comprehensive monitoring and diagnostics. The AMC-based controller (DAMC-TCK7) board was developed as a general purpose high-performance low-latency data Processing unit designed according to the PICMG MTCA.4 spec. The Module provides the Processing power, data memory, communication links, reference clock, trigger and interlock signals that are required in modern LLRF control systems. The Module was originally designed as a cavity field stabilizing controller for standing-wave linear accelerators. However, the application of the board is much wider because it is a general purpose data Processing Module suitable for systems requiring low latency and high-speed digital signal Processing. According to authors’ knowledge this is the first MTCA.4 Module offering 12.5 Gbps links, unified Zone 3 connectivity and advanced Module Management Controller proposed by DESY. The DAMC-TCK7 card was used as a hardware template for the development of the other AMC Modules of the XFEL accelerator’s LLRF system. This paper discusses the requirements for the digital real-time data Processing Module, presents the laboratory performance evaluation and verification in Cryo-Module Test Bench (CMTB) at DESY.
