基于PCI总线的VXI零槽控制器

PCI-VXI零槽控制器是内嵌计算机与VXI总线系统之间的桥梁.本文介绍了基于内嵌计算机PCI总线的VXI零槽控制器的硬件设计与实现,以PCI接口设计、PCI-VXI总线之间的转换和具有系统控者能力的VXI零槽电路设计为重点,主要讨论接口模块、同步异步时序转换模块的设计和实现.目前该模块已研制成功,并在实验室VXI总线测试系统中应用,实际应用表明,本设计方案完全符合PCI和VXI规范,能很好地实现PCI-VXI零槽控制器的全部功能,工作稳定,达到了预期的设计目标.

VXI slot 0 controller based on PCI bus

As a bridge between embedded computer and VXI bus system,PCI-VXI slot 0 controller is of high importance to the whole system.The realization and implementation of the VXI controller based on embedded computer PCI bus is developed in this paper.The Interface module design and synchronization asynchronism transform module realization are presented specifically with the key technology on PCI-VXI bus transform and VXI slot 0 circuit.Now the VXI slot 0 controller has been successfully used in actual automatic measurement system.It is indicated through experiment that this system fully comply with the regulation of PCI and VXI,and is capable of realizing the whole PCI-VXI slot 0 controller function with stable performance which achieves expectant objective.
