PCI Express Overview
• Serial interconnect at 2.5 Gbits/s
– PCI transactions are packetized and then serialized
– Low-voltage differential signaling, point-to-point, 8B/10B encoded
– x1 (by 1) has bandwidth of 250 Mbytes/s/direction
– x16 (by 16) has bandwidth of 4 Gbytes/s/direction
• Uses same software model as PCI
– Ensures software compatibility
• Roadmap for longevity with Gen-2 clocking (5 Gbits/s)
