Proposal of implementation of the "data link layer" of PCI-express
M. Aguilar, A. Veloz, M. Guzmán · 2005
This paper presents the proposal of the implementation of the Data Link Layer of PCI-Express, as is defined in PCI-Express Base Specification Revision Loa. The architecture presented here contains the transmission and receiver modules which ensure the reliably conveying of the Transaction Layer Packets VLP) between two components using the PCI-Express protocol. This document explains how the implementation makes the reliably conveying, through the addition of a sequence number and a 32-bit CRC to each TLP in the transmit side, and how the packets are processed in receiver side.
