本論文的目的主要是發展一塊能夠展現多媒體特性的高速ATM網路介
面卡於一般PC的平台上。PCI /ATM網路卡發揮了PCI匯流排的高傳輸率及
ATM的高頻寬。我們在PCI/ATM網路卡上一共設計並實現了三顆晶片。其中
有二顆是專門處理ATM/AAL5的功能﹐另一顆則是PCI控制器。PCI控制器的
角色類似於一座橋樑﹐負責傳遞主機CPU與PCI/ATM網路卡上的資料。這三
顆晶片都是利用Actel公司所推出的84隻接腳﹐PLCC包裝的ACT2 FPGA晶片
。由於PCI控制器的設計符合PCI匯流排的規格( 例如工作頻率﹐匯流排協
定等等 )﹐因此我們的PCI/ATM網路卡在插入PC使用時具有不需要調整任
何開關( 例如PC上I/O位址或IRQ的設定 )的特性。在本論文裡﹐我們將把
重點放在PCI/ATM卡上的PCI控制器之設計與實現。

The purpose of this thesis is to build a high speed ATM
networkinterface card ( NIC ) for supporting the multimedia
applications onthe PC platform. The PCI/ATM NIC combines the PCI
bus high transferrate and the ATM high bandwidth. Three chips
are designed andimplemented by ourselves in the PCI/ATM card.
Two FPGA chips are forprocessing ATM/AAL5 functions. The other
one is a PCI controller,which is as a bridge for the host CPU
and the PCI/ATM NIC throughPCI bus. All of the three FPGA chips
are implemented by Actel''s ACT284 pins FPGA chips. Because the
design of PCI controller follows thespecification ( such as
clock rate, bus protocol etc. ) of PCI bus,the PCI/ATM NIC can
be plugged into the PCs without setting anyjumpers, such as I/O
port address or IRQ number in the PCs. In thisthesis, we focus
on the design and implementation of PCI/ATM card which includes
an application specific controller.
