宿主机和并行处理机共享存储器模板的设计与实现

DESIGN AND IMPLEMENTATION OF A SHARED MEMORY BOARD BETWEEN HOST AND MPP

本文介绍了宿主机和并行处理机 (MPP)之间采用共享存储器模板的数据交换方式 ,设计并实现了具有一定通用性的共享存储器模板 .该模板采用主从式总线切换控制方法 ,存储器的组织方式可变 ,能够提供不同的访问带宽 ,可以为不同的宿主机和协处理机系统提供数据共享 .

This paper introduces the data exchange method of host machine and massively parallel processing by a shared memory board. Meanwhile a general shared memory board is designed and implemented. This board adopts Master slave bus control architecture. Memory pattern on this board are variable, so that varity data bus band width are provided. The board can be used in different system.
