Industry consortium PCI-SIG has published interface specifications of the latest PCI-Express 3.0.
The body, which overlooks the development and management based on the PCI bus data transfer standard, has made the new standard is backward
compatible with PCIe 1.x and PCIe 2.x. It has also included a measure of the number of transactions carried out by sending data at 8 GT/s, and the interface bandwidth is nearly 32 GB/s x16 configuration.
PCI-Express 3.0 runs the encryption scheme 128b/130b, which it claims can provide almost one hundred percent efficiency. There are also improvements in areas such as mechanisms for dynamically adjusting power consumption, the notification of admission for latency, scalability, and architecture. Specification of PCI-Express Base 3.0 is now available for members of the PCI-SIG, which include companies AMD, Dell, HP, IBM, Intel, LSI,
NVIDIA, and Oracle.
We are expecting first products to support PCIe 3.0 interface should appear around 2011.
