摘　　要：针对目前多业务传送平台产品中链路动态带宽调整机制(LCAC)功能模块实现的困难,提出了一种基于嵌入式处理器和现场可编程门阵列(FPGA)的软硬件结合的LCAS实现方案,并对其进行了功能仿真和基于FPGA的综合．仿真结果表明,这种软件实现协议的主体和硬件实现接口操作的方案具有极大的灵活性和高效性．To overcome the difficulty in LCAS design of MSTP devices, a co-hardware/co-software implementation of LCAS based on embedded-processor and FPGA is proposed. This solution has much more flexibility and efficiency, with implementing the principal part of protocol in software and the interface operation in hardware.
