Like everything else in Silicon Valley, PCIe (peripheral component interconnect express) is goin mobile (cue up The Who). The big news at the June PCIe Special Interest Group Developers Conference was mobile express, M-PCIe.
The advantages of consolidating interconnect technology include the usual driverscheaper to develop, fast as you want, fewer specifications for developers to master, better power managementand you wont need new drivers because every operating system already supports PCIe.
The essential ingredient to M-PCIe is incorporation of MIPIs physical layer, M-PHY. Its conceptually simple: replace the PCIe PHY layer with M-PHY and retain the rest of the PCIe protocol stackdata link layer, transaction layer, software layers and so forth.
