I2C, SPI Buses Get Update After 35 Years

It is a fact older technologies are either forgotten or remain in use by industry. Two examples are the I2C (Inter Integrated Circuits) and SPI (Serial Peripheral Interface) communication buses, which only now are receiving an update in the shape of the I3C protocol.

I2C was created in 1982, while the older SPI was born in 1979. The two buses drive short-range communications between circuits and microcontrollers, and remain the key interfaces for sensor-related communication in smart devices, wearables and computers. But such buses cannot handle the requirements of today's bandwidth-hungry sensors, bringing about the need for an update. Enter I3C, a bus combining I2C and SPI created by body in charge of interface specifications for mobile and mobile-influenced interfaces, the MIPI Alliance.

IDC: HPC Servers Bring Global Growth

High performance computing (HPC) servers bring growth, IDC reports-- global Q3 2016 revenues total $2.8 billion, a 3.9% Y-o-Y increase on Q3 2015 revenues worth $2.7bn.

The year 2016 is also on a positive track, as revenues for the first 3 quarters total $8.1bn, up by 3.4% over the same period last year.

"In Q3 2016, HPC was a bright spot in the overall worldwide server market, which IDC previously reported declined 7.0% year over year to $12.5bn in the quarter," the analyst says. "Higher-priced systems led the way with year-over-year growth exceeding 22%, while lower-priced system revenue declined."

HDMI Spec Reaches 2.1

The HDMI Forum announces version 2.1 of the HDMI specification-- one adding support for a higher resolutions and refresh rates, including 8K60 and 4K120, Dynamic HDR and increased bandwidth via 48G cable.

Developed by the HDMI Forum Technical Working Group, HDMI 2.1 is backwards compatible with earlier versions of the specification, and brings improvements on the audio as well as video sides. For instance, eARC provides a simpler solution for the setup of TVs with a soundbar or AVR complete with support for object-based surround sound formats such as Dolby Vision and DTS:X.

As mentioned earlier, a new 48G cable boosts bandwidth to 48Gbps for uncompressed support for 8K resolution video with HDR, while a Game Mode VRR features a variable refresh rate to reduce (if not eliminate) lag, stutter and frame tearing. Dynamic HDR adjusts depth, detail, brightness, contrast and colour gamut on a scene-by-scene or even frame-by-frame basis.

Brocade Expands SLX Networking Portfolio

Brocade follows on the SLX 9850 routing solution with a set of new SLX series products-- the SLX 9140, SLX 9240 and SLX 9540 switches-- together with new automation suites for Workflow Composer.

The SLX datacentre switches feature what the company describes as "unparalleled" network visibility, allowing customers to quickly identify problems, accelerate mean-time-to-remediation and improve overall service levels. They deliver leaf, spine and edge connectivity while leveraging the SLX Insight architecture.

The SLX 9140 is a fixed top-of-rack (ToR) switch providing forty-eight 25GbE ports and six 100GbE ports. The SLX 9240 is a fixed spine switch with 32 x 100/40GbE ports, while the SLX 9540 offers up to 48 x 1/10GbE ports. Both 9140 and 9210 also include a programmable ASIC using silicon from Cavium XPliant.

Top Five Networking Predictions for 2017

David Galton-Fenzi, CEO of Zycko, specialists in advanced networking, and CCO of Nuvias Group (of which Zycko is part), looks towards 2017 and gives his top five networking predictions

Software Defined Networking

The move to-software-defined-everything will continue in 2017, and some of the biggest disruptors in the networking market will be Software Defined Networking (SDN), Software Defined Wide Area Networks (SD-WAN), and Software Defined Datacentre (SDDC).

By abstracting some of the functionality of the network into a software application, SDN allows network administrators to more easily manage dynamic networks. It has the added benefit of being non-proprietary, allowing users to integrate to any environment, offering a more flexible and price-conscious alternative to vendor-specific hardware.
