摘要
设计实现了一个可复用的面向并行DSP应用的消息传递软件框架.为了实现DSP软件的编码能够独立于不同的并行处理器体系结构,设计分层的软件框架结构和各层中类间的关系.为了DSP应用的开发能够独立于底层的数据通信路径,提高并行系统的可扩展与可配置性,设计基于处理器间数据流模型和硬件平台拓扑模型的节点路由表结构和路由算法.以TigerSHARC DSP构成的并行DSP系统为例,说明软件框架应用于特定的多处理器平台的方法,实现并验证了消息传递软件框架.
This paper presents a layered message passing software framework and an efficient mechanism that decouples signal processing algorithm design from details of data communication for special-purpose parallel DSP system.We also described the structure of each layer and the interaction between layers.Inter-processor communication model and hardware platform topology model are used for the design of shortest path route algorithm for the needs of creating transferring table in which the router information is stored for each DSP node.Finally,the framewok is applied to a TigerSHARC DSP multi-processors plateform.
