提出一种基于DSM的可在线重构多DSP并行处理架构,采用基于自定义内部总线的信息传递服务,在分布式物理内存上实现了统一编址的共享内存模型,减小了DSP之间的数据传递开销;设计基于VME总线的在线重构来实现针对消息传递服务的重定义,增强了并行计算架构的通用性.实验表明,采用此DSM能减小了并行DSP对共享数据同步访问开销,满足多轴精密同步运动控制系统需求.
A DSM-based on-line reconfigurable multi-DSP parallel processing architecture is proposed. By using the information transfer service based on a custom internal bus, a unified addressable shared memory model is implemented on the distributed physical memory, reducing the number of Data transfer overhead, design online reconfiguration based on VME bus to realize the redefinition of messaging service and enhance the commonality of parallel computing architecture.Experiments show that using this DSM can reduce the overhead of parallel data access to shared data, Meet the needs of multi-axis precision synchronous motion control system.
