Where Biology Inspires Circuit Engineers – The Neuromorphs

0

The fundamental philosophy of neuromorphic engineering is to utilize algorithmic inspiration of biological systems to engineer artificial systems. It is a kind of technology transfer from biology to engineering that involves the understanding of the functions and forms of the biological systems and consequent morphing into silicon chips.

 

For instance, the study of the structure of the muscle in an animal inspires the creation of locomotive robots that do not rely on heavy and power hungry servo motors. The fundamental thing is to understand how biological nerve tissues represent, communicate and process information. That would become the prelude to engineer electronic devices. Understanding the biologically algorithms of animals are vital and fundamental to reverse engineer the biological systems information representations and then develop systems that use these representations in their operations.

 

The fundamental biological unit mimicked in the design of neuromorphic systems is the neurons. Animal brain is composed of these individual units of computation, called neurons and the neurons are the elementary signaling parts of the nervous systems [9]. Neurons, which have common shape, produce electricity or chemical signals to communicate with other neighboring ones.

 

Though these neurons are similar in shape, different connections with each other, muscles and receptors produce different computational results in biological systems: locomotive control, perception, sensory processing, auditory processing etc. Neuron is made of made up of input area (the dendrite) and output area (the axion) and is connected with other neurons by synapses.

 

Since neurons are the basic cells of the nervous systems of all kinds of animals, building silicon neurons (or neuromorphs) endowed with fundamental life-like characteristics, could enable the emulation or modeling of the neural networks in biological nervous systems.

 

By examining the retina for instance, artificial neurons that mimic the retinal neurons and chemistry are fabricated on silicon (most common material), gallium arsenide (GaAs) or possibly prospective organic semiconductor materials.

Layers In Technology Pyramid – The Closer To Top, The Higher Your Wealth Creation Power

5

Technology is the leader of the enterprising world. And it leads using a constitution. Unlike the traditional political structure, this constitution is Algorithms written by engineers, scientists, etc and not congressmen and politicians.

 

The global competition is largely who has the best technical group to write the best one; in this case, Algorithms, that comprise of patents, technical processes, tools, and so on. As a nation develops, adopts, applies and diffuses appropriately the contents of this constitution, it elevates the lives of its citizens. The more innovation a nation pursues, the more it refines this constitution.

 

Economists have shown a correlation between Knowledge Economy Index (KEI), productivity and standard of living. The challenge for any nation is to improve its KEI number. Doing that involves good education, economic regime and other variables that help to improve technology capability.

 

The age of natural resources dominating global commerce and industry is gone. What matters now is creating knowledge and applying it. Some nations will create, others will merely consume. But wealth is concentrated at the creative stage and nations that focus on consuming, without creating technology will not prosper.

 

Even with abundance of natural resources, which in many instances, the consuming nations cannot independently process without the knowledge partners will not change this trajectory of limited national wealth without technology creation.

 

On this basis, I separate the two layers where nations use and compete with technology as upstream and downstream layers. It is like a two layer pyramid where the downstream is at the bottom with the upstream seated on top. What happens here is that some nations focus on the downstream layer while others combine both the downstream and upstream layers.

 

The most advanced nations combine the two layers as they seek international competitiveness. They provide technology roadmap that looks at the future and have plans to take advantages that technology brings.  They create and develop things and in the 21st century are classed as knowledge driven economies. In those nations, there is planning for continuity and technology succession.

 

For the other nations, usually developing, they compete at the technology pyramid primarily at the downstream layer. They lack the know-how to create things and commercialize technology intellectual properties. The nations are not driven by technology, rather commodities. They are prone to trade shocks and are usually economically non-vibrant. They fail to create wealth using technology and participate in the pyramid as consumers or prosumers.

 

Let me illustrate using Nigeria where they speak the language of petroleum. In the petroleum industry, there are the downstream and upstream sectors. While the upstream focuses on exploration of crude oil, downstream does the distribution and marketing.

 

The money is in the upstream sector, a major reason we have the foreign partners concentrated therein. That is where the knowledge creation is done and utilized in the industry. I am cautious to say, without the knowledge partners in Nigeria, helping to explore this crude oil, Nigeria cannot mine this product. Verdict: the oil will be there and of no tangible economic use.

 

This will follow a pattern where villages have water underneath them but no drilling expertise to harness the water for cooking and drinking. That is the problem of anchoring national strategy at the downstream level. It lacks inventiveness.

 

In Africa and many developing countries where ICT has been embraced, they rarely know that there is more value than what ICT gives them. Sure ICT has helped many developing countries to improve their business processes, tools and people.  They are so excited on the powers of quicker and faster communication. They savor the wonders of email, Internet and mobile phone and many more.  These experiences are primarily on marketing, distributing and installation of these ICT systems. They rarely make them and can only play at the downstream layer.

 

There economists point out repeatedly the innovations ICT has brought to the economies. I agree, ICT is wired for innovation in so many areas. Nonetheless, the good news is that there are more benefits up in the pyramid if you move up to the upstream layer. By not creating technology, our techno-economic benefits are limited and this will not change until we move up the pyramid.

 

Though this point can be illustrated with any technology, I will use the ICT because it is common and familiar to people. I have already illustrated the point in the petroleum industry where many developing nations depend on petroleum refining technology of the developed countries to extract the oil. Even if they develop technologies for the distribution, the upstream idea will triumph. Nations make more money to license technologies at the upstream level compared to the downstream.

 

Back to ICT, the upstream level will involve designing computing systems, cellphones, routers, device drivers, and all other infrastructures that enable ICT revolution. Instead of importing the latest cellphones, we will think how to design them. In 80% of the developing nations where mobile technology is used, less than 2% of the technologies are designed and manufactured there.

 

Yes, there are businesses that distribute and sale these gadgets and make marginal profits.  They can import a laptop from China at $500 and sell to their customers at $650. Because the barrier to entry is so weak, the margins are small.  Everyone is selling and there are shops everyone. They are technology firms to their nations because they can load the software and configure the networks and get the laptop working.

 

Compare that with giants like Intel and AMD that take a piece of sand (silica) and process it. At the end, that piece of sand of say a $1 can be sold for $3,000 because of the knowledge involved to transform the sand to a microprocessor. That is knowledge and the very best of human imagination and creativity. It is playing technology at the upstream level and that is where the value is.

 

Nations win at the upstream level because the sale margins are so huge because the products are niche and in most cases innovative with few players internationally. It is not just the trade or margins. Upstream technology layer create good jobs, whether in developed or developing nations. Some of the best jobs in Africa are in the oil giants where upstream technology rules.  You create enviable good jobs for the citizens. They have the money to spend and lift other areas of the economy. They hold jobs that bring honor and dignity and they use their brains to shape the world.

 

You can make the same case for Pharmaceutical firms that mix elements, compounds, etc to create drugs.  Some of the drugs are really expensive but the ingredients are cheap. People pay for the R&D invested in developing that drug.  In developing nations, they focus on marketing and selling the drugs. As in petroleum, ICT, it is all about the downstream. Why the big Pharma can have margins of 1000%, these entities can barely command 6% margins.

 

So in essence, in this century, there are opportunities for nations. For developing nations, if they continue to compete at the downstream layer of the pyramid, they will find it hard to move forward since competition is basically synonymous with technology. There is more risk, more knowledge requirement and more value at the upstream.  And we need to get there.

 

How do we do that? Our nations must have fundamental changes in our national policies on technical education or better Science, Technology, Engineering and Mathematics (STEM). That is the answer. I believe in knowledge and education evolves it. It is about expansion of commitments on microelectronics, nanotechnology, biotechnology, mathematics, chemistry, physics, computer science, engineering, medicine, and so on and within a generation we can become players at the upstream level of technology pyramid. And reap that great value therein.

European Economic Uncertainty – The Sovereign Debts Bombs. What African Union Must Learn

0

The financial crises in arising from the PIIGS (Portugal, Ireland, Italy, Spain) could potentially pose serious problems in Europe. If Greece is allowed to default, there is possibility that Portugal will follow. This will be like a financial crises tsunami with Armageddonic scale impacts. In short, the very basis of modern Europe could be revamped.

 

With billions of dollar exposure to Greek banks, Germany, France and even the US financial institutions could potentially face tough roads ahead. And these crises could be prolonged because jobless recovery is making it hard to get over the recession. The old way of exporting yourself out of this type of problem is not going to happen because the balance has tilted. Americans are now cautious buyers and the world has cooled off in prosumer and consumer spending spree.

 

Watch out, if European leaders fail to get this solved in coming days quickly, they could see damages that will linger for years. Right now, the cost of borrowing in Europe in these nations is up and many social services will be cut-off by governments. As Greeks have shown yesterday, they will not accept this belt tightening without a fight. These guys set a bank on fire.

 

What is happening today could trigger social crises across Europe if Greece is allowed to default. It used to be corporate debt, now, it is sovereign debt that is the disturbing the world.

 

I am getting worried that these debt crises could weaken the recovery and possibly create a domino effect across European nations.  It is not the best of times in Europe right now.

 

And this is a lesson for the African Union to step back on the single currency plans. It is all about the weakest link.

Power Dissipation And Interconnect Noise Challenges In Nanometer CMOS Technologies

Power dissipation and interconnect noise challenges in nanometer CMOS technologies

by Ekekwe, N.

Abstract

The invention of the complementary metal oxide semiconductor (CMOS) integrated circuit (IC) is a major milestone in the history of modern industry and commerce. It has driven revolutionary changes in computing due to its performance, cost, and ease of integration. But as the size of the transistors reduce into the nanometer scale, so many challenges occur with the reliability and performance of the systems. In the past few decades, the advancement of chip performance has come through increased integration and complexity on the number of transistors on a die. However, this progress has been followed with increased power dissipation and interconnection noise in circuits. Both are costly in terms of shorter battery life, complex cooling and packaging methods, and degradation of system performance.
