Virtualizing the World of Cable
By Wayne Hickey – When cable operators saw huge demands in linear video, Video-on-Demand (VoD) and high-speed data services, and faced with an aging analog infrastructure, they moved to a Converged Cable Access Platform (CCAP) to increase capacity and throughput. CCAP combines headend functions into a single architecture by combing Edge Quadrature Amplitude Modulation (EQAM) and Cable Modem Termination System (CMTS).
Back in June 2011, CableLabs created CCAP by blending two competing platforms, a Comcast-backed Converged Multiservice Access Platform (CMAP) and a Time Warner Cable Converged Edge Services Access Router (CESAR) platform. The following year CCAP products were introduced, and deployed the year after.
Fast forward to today, cable operators are looking to implement software-based access platforms, migrate away from commonly deployed centralized, purpose-built CCAP equipment, and virtualize CCAP (vCCAP) — and thus begin the shift to a Distributed Access Architecture (DAA). Developed by CableLabs, vCCAP is the latest cable technologies that combines functions including the CMTS and EQAM.
Virtualizing and distributing MAC and PHY functions enables digital combining, eliminates analog optics with cost effective 10G Ethernet transport, and converts analog fiber nodes to digital optic IP-enabled devices. DAA makes it easier to push fiber deeper into the edge of the network, and along with the ability to support denser wavelengths for each fiber, digital optics greatly improves Carrier-to-Noise-Ratio (CNR), which will enable higher orders of QAM on the coax and higher performance DOCSIS technologies. more> https://goo.gl/EoPwPL

By Dave Lammers – It was back in 1985 that Ross Freeman invented the FPGA, gaining a fundamental patent (#4,870,302) that promised engineers the ability to use “open gates” that could be “programmed to add new functionality, adapt to changing standards or specifications, and make last-minute design changes.”
Freeman, a co-founder of Xilinx, died in 1989, too soon to see the emerging development of embedded field programmable logic arrays (eFPGAs). The IP cores offer system-on-chip (SoC) designers an ability to create hardware accelerators and to support changing algorithms. Proponents claim the approach provides advantages to artificial intelligence (AI) processors, automotive ICs, and the SoCs used in data centers, software-defined networks, 5G wireless, encryption, and other emerging applications.
With mask costs escalating rapidly, eFPGAs offer a way to customize SoCs without spinning new silicon. While eFPGAs cannot compete with custom silicon in terms of die area, the flexibility, speed, and power consumption are proving attractive.
Achronix Semiconductor (Santa Clara, Calif.) has branched out from its early base in stand-alone FPGAs, using Intel’s 22nm process, to an IP model. It is emphasizing its embeddable Speedcore eFPGAs that can be added to SoCs using TSMC’s 16FF foundry process. 7nm IP cores are under development.
Efinix Inc. (Santa Clara recently rolled out its Efinix Programmable Accelerator (EPA) technology.
Efinix (efinixinc.com) claims that its programmable arrays can either compete with established stand-alone FPGAs on performance, but at half the power, or can be added as IP cores to SoCs. The Efinix Programmable Accelerator technology can provide a look up table (LUT)-based logic cell or a routing switch, among other functions, the company said. more> https://goo.gl/nXqYvV

Declarative Configuration when Change is Constant
By Dave McLeish – Change is a double-edged sword. To set the scene let’s first focus on recent change for the good as relates to our own domain of product lifecycle management (PLM). In the past few years, increased mobility with smart phones and tablets has provided new opportunities for mobile access to PLM. Adoption of familiar user interface (UI) patterns from everyday life (shopping cart, smart search) and enhanced possibilities for user experience through touch and virtual assistants have enabled more of the “extended enterprise” to embrace PLM. From the shop floor where there’s touch screen access to work instructions to executives empowered to simply search, sign off and interact with dashboards on their device of choice, increasingly the whole enterprise can contribute to and view the digital thread from product development to delivery.
At the heart of this change for the good is the rich web-based access to PLM that has been made possible by html5. Rich capabilities that have meant we can begin to reimagine how we collaborate and deliver products from inception, through realization and utilization. Zero-install rich, browser-based solutions remove the need for desktop install and reduce the IT deployment overhead through firewall friendly standard https requirements.
But developing in the browser has its challenges when targeting rich capabilities over high latency WAN and with limited memory resources. Arguably the greatest challenge is managing change. Whilst the emergence of HTML5 and CSS3 among other standards have provided a reliable basis for developing web solutions, the same cannot be said for much of the web development space. more> https://goo.gl/NjgcsC

By Raya Bidshahri – To contribute to human progress, it is not enough to be intelligent, resourceful, or well-connected. Those are all factors that play a significant role but aren’t the true driving forces of disruptive innovation. Stimulating positive change at civilization level also requires certain mindsets and ways of thinking.
Here are five mindsets that will allow us to leave a positive mark on humanity.
- Curiosity and Critical Thinking
One of the tragedies of our education system is that it fails to nurture the childlike sense of wonder that we are all born with.
- Intelligent Optimism
Nothing productive will come from blind optimism and ignorance of some of the brutal realities of our world.
Paving a new way forward for humanity comes at a cost. More often than not, executing a radically disruptive idea is a risk.
- Moonshot Thinking
Instead of looking to make a 10 percent gain or improvement in a current product or idea, moonshot thinking involves aiming for a 10x improvement of the status quo.
- Cosmic Perspective
We’ve all heard of “thinking big” or ‘big-picture thinking.” Moving beyond that involves having a cosmic perspective.
It’s about asking the right questions, being intelligently optimistic about the future, taking a risk with a moonshot, and maintaining a cosmic perspective. more> https://goo.gl/V2bVjb

By John Detrixhe – The German bank’s study of developed markets uses this criteria to define a financial crisis: on a year-over-year basis, a 15% drop in stock markets, 10% decline in foreign-exchange, 10% fall in bonds, 10% increase in inflation, or a sovereign default.
Deutsche Bank argues that crises have been increasingly frequent since the breakdown of the Bretton Woods system, which, after World War II, fixed exchange-rates and essentially linked them to the price of gold. That coordination ended in the 1970s when the US broke the dollar’s peg to the yellow metal. The link to a finite commodity helped limit the amount of debt that could be created.
As strategists at the Frankfurt-based lender see it, the resulting fiat money system has encouraged rising budget deficits, higher debts, global imbalances, and more unstable markets. At the same time, banking regulations have been loosened. In the US, the industry may soon have fewer restrictions and less oversight, a mere 10 years since the last worldwide crisis. more> https://goo.gl/vDnQ2w
