A liaison agreement has been signed to extend the benefits of the PCIe I/O standard to mobile devices including tablets and smartphones.
The PCI-SIG and MIPI Alliance are working together to deliver an adaptation of the PCI Express (PCIe) architecture to operate over the MIPI M-PHY physical layer technology.
The adaptation of PCIe protocols to operate over the M-PHY is targeted to be released as an ECN to the PCIe 3.0 Base specification and will achieve full integration into the PCIe 4.0 Base specification upon its release. The initial application of this technology is anticipated to be high-performance wireless communications with other applications based on device design requirements.
Future implementations are expected in the handheld device market, including smartphones, tablets and other ultra-low power applications. Implementers of this technology must be members of both PCI-SIG and MIPI Alliance in order to leverage member benefits including access to licensing rights and specification evolutions.
PCIe technology is supported in major operating systems, has a robust device discovery and configuration mechanism, and provides power management capabilities. The EMI-friendly, bandwidth scalable, low-power MIPI M-PHY physical layer enables device manufacturers to ue the highest performance and most power efficient data transport interface technology.
The layered architecture of the PCIe I/O technology facilitates the integration of the power-efficient M-PHY with its extensible protocol stack to deliver best-in-class and highly scalable I/O functionality for mobile devices.
