摘　　要：介绍了一种具有通用性的主机接口主设备后端逻辑的设计实现。基于特定应用环境下,依据应用需求,控制需求及数据传输特点,提出了一种具备通用性、易于调试的主设备后端逻辑电路设计,能够通过主设备后端逻辑对外部主机内存读写操作,实现了后端逻辑作为主设备时,从外部主机中读取或写入初始化过程中主机内存分配空间中的数据或后端逻辑所需命令。This essay proposed a method of design and implementation in host accessing control function based on a particular graphic processing unit（GPU） project. according to requirements of the specific GPU project including require of control and data flow,the function of host accessing control（HAC）which would be universality and to be debugged easier when errors or problems founded in system test,had been achieved. This HAC could allow the other functions or the algorithm units of GPU project to access internal storage or memory of host device which should be an individual device out of GPU project both read accessing and write accessing.
