What’s inside your computer (INFOGRAPHIC)

Some of you who have a traditional “three-piece” desktop computer system where there is a separate box where all the activity takes place, may refer to this box of your computer setup as the “hard disk” even though it is known as a “system unit”. This is because the hard disk, amongst the other key computing subsystems like the CPU processor and the RAM exists in that box.

This infographic shows what the key parts of your computer are and is based on one of the newer small-form-factor designs that are common in the office and home.

The EU stands behind the creation of a “semiconductor Airbus”

L’UE appelle à la création d’un « Airbus des puces » | Le Monde Informatique (France)

My Comments

The European Union does play host to some electro-technical activity, whether in the form of research or design and manufacture of finished product. Think of names like Philips, Pace (set-top box applications), Loewe, B&O, Nokia and Siemens amongst many others when it comes to finished applications. Or you may think of Acorn who has built up the ARM microarchitecture used in most smartphones and tablets or B&O who have built up the ICEPower reference design for high-quality Class-D switching power amplifiers. As far as semiconductors and microelectronics are concerned, STMicroelectronics is the only European representative in the 10 main semiconductor companies.

But there has been a call for the European Union to strengthen a European-grown microelectronics industry. They effectively want to see a “digital Airbus” or “Airbus for semiconductors”. This is where Airbus, the France-based European aerospace name, has become associated with building the impressive airliners like the A380 superjumbo and been in a position to challenge established players like he US-based Boeing.

Here, the European Commission wants to launch an industrial plan to seed the European semiconductor industry by making Europe financially attractive to invest in for this industry. This encompasses the research and development aspect; as well as production of the components; and they want the European Union and its constituent Member States to work together on this.

What I see of this is that the European “finished-products” names could move towards the local “Airbus for semiconductors” once they see that the products can work well with their finished-product designs. Similarly, if this company can answer established firms like Intel, AMD and NVIDIA for CPU or graphics-processor designs, this could be a chance for Europe to facilitate a lively competitive microprocessor market.

Processor Chipsets with built-in Graphics


BBC News – Intel to launch chipsets with built-in graphics

My comments

With Intel now showing interest in supplying a processor chip with an integrated graphics processor, this will raise the stakes when it comes to supplying single-chip CPU / GPU solutions.

Why supply a single-chip CPU/GPU solution

There is the obvious benefit in design size that it would yield. This would of course allow for more compact applications and, of course, the bill-of-materials costs would be reduced thus allowing for cheaper devices. Another key benefit would be that the single-chip solution would have reduced power needs, which is important for battery-operated devices like laptops, tablet computers and, especially, smartphones.

There is also the reality that most consumer electronics devices like electronic picture frames, digital cameras, TVs / video peripherals and hi-fi equipment are being designed like the general-purpose computers and most of them will also benefit from these CPU/GPU chips. This has become evident with most of these devices offering network and Internet connectivity in a way to augment their primary function or beyond that primary function.  They will also yield the reduced “bill-of-materials” costs and the reduced power demands for this class of device which will become a market requirement.

Similarly, an increasing number of office equipment / computer peripherals, home appliances and “backbone” devices (HVAC / domestic-hot-water, building safety / security, etc) are becoming increasingly sophisticated and offering a huge plethora of functions. I had noticed this more so with the multifunction printers that I have reviewed on this site where most of them use a colour bitmap LCD display and a D-toggle control as part of their user interfaces.

Therefore manufacturers who design these devices can benefit from these single-chip CPU/graphics solutions in order to support these requirements through reduced supporting-power requirements or design costs. In the case of “backbone” devices which typically require the uses to operate them from remotely-located user-interface panels i.e. programmable thermostats or codepads, there isn’t the need to require too much power from the host device to support one or more of these panels even if the panel is to provide access to extended functions.

The market situation

The Intel Sandy Bridge which is just about to be launched at the time of publication, would provide improved graphics. This is in a market which AMD has just entered with their Zacate CPU / graphics chip and been dominated by ARM who have been involved in the smartphone scene. This firm’s design was infact used as part of the Apple A4 chip used in the iPhone 4 and iPad.

With three companies in the market, this could yield a highly-competitive environment with a run for high-quality quickly-drawn graphics, quick CPU response, power conservation / long battery runtime and small circuit size / reduced bill-of-materials. This may also yield a “run for the best” which also yields desirable functionality being available at prices that most people can afford.

The only limitation with this concept is that the single-chip design may make the market for discrete graphics chipsets and cards only for people who value extreme-performance graphics.


The reduced size of these new single-chip CPU/GPU setups could replicate the success of what has happened with the arrival of the 80486 processor with its integrated floating-point coprocessor. It could then make for a longer battery runtime for portable applications and lead to smaller cooler-running computers for most applications.
