PCI9656的研究与应用

Research and Application of PCI9656

PCI总线是当前计算机系统中广泛存在的标准总线。PCI总线按照数据宽度可以分为32位和64位两种,按照总线的工作频率可以分为33MHz和66MHz两种。随着卫星下行数据率的不断提高,普通32位33MHz的PCI总线峰值数据传输速率不能满足后续卫星的数据接收要求,在这种情况下,本文进行了64位66MHz的PCI总线的研究。在64位66MHz的PCI总线下,数据传输率可以达到528MByte/S,即4.2Gbps,可以满足今后数年之内的高速率卫星数传接收的需要。

PCI bus is widely used in computer systems today.PCI bus can be divided into 32bit and 64bit,can work at 33MHz or 66MHz.With the increase of the data rate of satellites,32bit and 33MHz PCI bus can’t transfer such high speed of data.This paper discussed about the 64bit and 66MHz PCI bus,which can transfer 528MByte per second(4.2Gbps).The device based on 64bit and 66MHz PCI bus can satisfy the needs of satellite data receiving in the future several years.
