Direct access to flash memory via PCI Express (see NVM Express: Flash At PCI Express Speeds) looks to replace disk-based interfaces like SATA and SAS (see What's The Difference Between SATA And NVMe?). Flash can utilize all the bandwidth of x8 PCI Express interfaces while single hard drives struggle to fill one lane. Arrays of hard drives can deliver higher bandwidth but they still suffer from access latency that is minute for flash storage.

When debugging and troubleshooting automotive serial buses, you can choose from a variety of test-system configurations. Products on the market are able to support Controller Area Network (CAN), Local Interconnect Network (LIN), and FlexRay buses as well as the emerging Media Oriented System Transport (MOST) bus supported by the MOST Cooperation, and BroadR-Reach, a technology developed by Broadcom and supported by the OPEN Alliance (One-Pair Ether-Net) Special Interest Group in conjunction with the University of New Hampshire InterOperability Laboratory.1

The University of New Hampshire InterOperability Laboratory (UNH-IOL), an independent provider of broad-based testing and standards conformance services for the networking industry, announces the launch of the Automotive Ethernet Consortium, paving the way for semiconductor companies to address stringent requirements of the automotive industry for next generation in-vehicle networking. The OPEN Alliance (One-Pair Ether-Net) Special Interest Group (SIG) endorses the UNH-IOL as the first laboratory to test BroadR-Reach®, a standard that will achieve 100Mbps Ethernet connectivity in automotive networking applications.

TMCNet readers are most likely familiar with Metcalfe’s Law: the value of a network increases with the number of people connected to that network – or Moore’s Law, which addresses the exponentially growing power of computer processing. I’ve also observed another phenomenon that may deserve its own moniker. Let’s call it the Ethernet Law.
