How to implement PCI-Express ?

[vlsi_whiz]

Hi,

I want to implement the PCI-express functionality , like in PCI we had the Master/Target interface. In PCI-e however, the spec talks about PCI-e endpoints and switch fabric! How do I go about implementing PCI-e functionality ?? Any suggestions??

Also two books from intel on the subject are available.

This link is will take to the intel the books on design of PCI express

Also this doc helps u to understand how to dessign High bandwidth Interconnect using the Virtex-5 LXT PCIe Endpoint Block which is a configurable Single-chip Solution

Hi
First let me now ..what u want to implement .is than an endpoint/Root complex . u want to implement a BFM or RTL IP . I suggest u to read Mindshare and then start to implement . If u have any doubts feel free to ask .

 

[lty]

the PCIE root complex is like a host bridge;
the PCIE endpoint is like a normal PCI device;
the PCIE switch is like a PCI to PCI bridge;
there are many similar concepts between PCI and PCIE. but PCIE uses packet for its transactio.

you can refer the book :
