The History of PCI IO Technology: 30 Years of PCI-SIG® Innovation

Presented by

Dr. Debendra Das Sharma, PCI-SIG Board Member

About this talk

For the past 30 years, PCI-SIG® has delivered IO technologies and specifications that move the technology industry forward and has grown to over 900 members worldwide since its formation in 1992. PCI technology debuted in 1992, supporting a peak throughput of 133 MB/s and a clock speed of 33 MHz, and soon became the standard bus to connect components in a computer system. PCI-X (PCI extended) followed in 1998 providing bandwidth boost required by the industry and this was followed by a significant transition to PCI Express® (PCIe®) architecture in 2003. Since its debut, PCIe technology has evolved over six generations to meet the needs of diverse applications and markets, including Data Center, Servers, Cloud, High Performance Computing (HPC), AI/ML, IoT, Automotive and Military/Aerospace. In this webinar, PCI-SIG Board Member Dr. Debendra Das Sharma of Intel, will provide a technical deep dive on the industry transitions over the past 30 years, platform transformations, and how PCIe technology has evolved through data rate transitions and protocol enhancements to meet the needs of the compute continuum. Attendees will learn the rationale for the shift from 5 GT/s 8b/10b of the PCIe 2.0 specification to 8 GT/s 128b/130b of the PCIe 3.0 specification. Participants will also learn the protocol enhancements of the PCIe 3.0 specification for accelerators and the low-power substates for applicability to hand-held devices, as well as the technical considerations for the PCIe 4.0 and 5.0 specifications. The webinar will cover the shift to the PCIe 6.0 specification at 64 GT/s and the transition to PAM4 signaling. Finally, Dr. Das Sharma will highlight what’s in store for the future of PCIe technology and how PCI-SIG will continue to meet the needs of the broader compute continuum.
