摘　　要：RapidIO是一种基于包交换的体系结构,为高性能的嵌入式系统内部互连通信提供了良好的解决方案,其特点在于能提供多处理器系统点对点的对等通信能力,能够满足嵌入式系统对高速、高带宽、低延迟和低功耗的苛刻需求,在网络通信、存储网络、军事技术及工业自动化领域有着广泛的应用。设计了一种基于RapidIO技术的信号处理平台,具有可重构性的优点,算法工程师可以根据算法的具体需要,在不改变硬件平台的条件下,搭建出更加适合算法数据流向的的网络拓扑结构,从而提高平台的可复用性以及数据的传输速率。重新搭建出更加优化的DSP网络拓扑结构,从而提高数据的传输效率。The Rapid IO is a kind of architecture based on packet switch, it provides the good solutions for interconnectiom within high performance embedded systems. It features in providing the point-to-point and peer-to-peer communication capacity for multi-processor system, can satisfy the strict requirements of embedded systems such as high speed, high bandwidth, low delay and low prover consumption, and has wide applications in the fields of network communication, storage network, military technology and industrial automation. This paper designs a signal processing platform based on RapidlO technology, which has the reconfigurability feature. According to the specific requirenlents of algorithm and under the condition of the hardware platform without changing, the algotithm engineer can construct the network topology structure which is more suitable for direction of algorithm data flow, in order to improve the reusability and data transmission rate of platform and reconstruct the more optimal DSP network topology structure to improve the data transmission efficiency.
