Obsolete Electronic Components, No More Outdated

Even if you know nothing about electronic components, you know that electronics become obsolete when they reach store shelves. Manufacturers are always making things bigger and better, which means that when we buy something new is not something else that is better than you are about to be released.

For this reason, it is possible to buy and sell electronic componentsobsolete if you have to sell or if necessary for an electronic device that is always used, even if it is not the latest version of the theme.

Obsolete electronic ticket

Do you have an old computer, television, cell phone or video game system that I love you and are not willing to give? Many electronic devices do not last too long already, but sometimes you just have a piece to replace and can be run like new. If you try to prolong the life of your electronic device, inexpensive way to do this may be to buy obsolete electronic components.

Many times you can buy these parts for very little and can repair your appliance. This is often much more affordable to go out and buy the latest model, and if you look up to the point that everything can be wiser for you to fix it instead of buying the latest model.

You can buy obsolete electronic componentsfrom many different sources. You may be able to buy a variety of auction sites, local authorities of their parts, and surprisingly, even from garage sales, etc! Many people consider obsolete electronic waste, so you can get these parts for almost nothing in many cases.

One thing you must be sure that when buying obsolete electronic componentswhich are in good condition if you intend to use.

Electronic components obsolete sale

Sale of obsolete electronics is something that almost everyone can do. Why? Because we all have something probably obsolete electronics in our homes, many of whom do not want, but do not know what to do. They say a man’s trash is another treasure, and could not be more true than it is with obsolete electronics.

If you have electronics or electronic componentsthat are updated, it is likely that you could sell your own account on an auction site or even a parts distributor and earn money with the offer . May not be able to withdraw money you make, but it’s a great way to get rid of obsolete parts that do not need or want.

New Features of Intel's Next Generation Processor--Poulson

At last week's Hot Chips conference in California, Intel released the updated architecture features of its upcoming Itanium processor with the codename as "Poulson". The new architecture features include Instruction Replay, improved Hyper-Threading and new instructions and so on, aiming to use the next-generation 12-wide release architecture. The Instruction Replay technology is one of the new features, which could make the wrong instruction re-execute, and then automatically cover the serious mistakes and further help to prevent the system collapse and data damage. Additionally, this Instruction Replay technology is an important remote access services update and the first Intel chip to have the capability. General Manager at Intel's Data Center Group, Pauline Nist said, "utilizes a new pipeline architecture to expand error detection in order to capture transient errors in execution. Upon error detection, instructions can then be re-executed from the instruction buffer queue to automatically recover from severe errors to improve resiliency." Besides these, for almost all main architectures in the Itanium electronic components core design, "Poulson" adds extensive RAS (reliability, availability and serviceability) protections, including LLC (last level cache), MLI (mid-level instruction cache), MLD (mid-level data cache), IEU (integer execution unit) and FPU (floating-point unit), etc. This technology enables the second feature, improved Hyper-Threading which brings better performance and support for Dual Domain Multithreading. This allows for front and backend pipeline execution, therefore improving Poulson's parallelism. Moreover, Intel is adding instructions in four areas as well. There are new integer operations, expanded data access hints, expanded software prefetch and thread control. It is worthwhile for Xeon customers to keep an eye on Itanium updates and features because they are likely to appear in future Xeon CPUs. The new Itanium instructions of Intel simplify unified task and branch operations to help the future Itanium to promote into the next level. Key points of "Poulson": * Eight high capacity core * 54MB memory chips (50MB of an SRAM) * Adopting 32 nm made 3.1 billion transistors * The higher, the bus speed (QPI and SMI) will increase 33 percent system bandwidth * The next generation of architecture improves the new data and instructions channel, floating point channel and instruction cache. * Improve the power management function, reduce the socket power consumption. * Compatible with the present Intel Itanium 9300 processor series. Intel announced that "Poulson" Itanium processor is the most advanced Intel processor so far which is about to launch in 2012. The next-generation Itanium processor followed "Poulson" is code-named as "Kittson" which is being developed and would be released in 2014.

Additionally, a B2B platform for foreign trading of electronic components, Hqew.net, affiliated to Huaqiang Holdings Limited as well, would follow President Hu’s words and try to be more successful and well-known around the world.

ARM Processors: We Are Being Stronger on PC Market

According to electronics’ latest news, it said that ARM is expected to achieve its biggest successes in the value notebook segment during the next few years.

Figures from processor market said that Spurred by next year’s introduction of Microsoft Corp.’s new ARM-enabled Windows 8 operating system, ARM-based systems will account for 22.9 percent of global notebook PC unit shipments in 2015, up from 3 percent in 2012. Shipments will reach 74 million ARM notebooks in 2015, compared to 7.6 million in 2012.

IHS expected that with shipments of ARM processors set to soar in the coming years and projected to appear in nearly one out of every four notebook PCs made in 2015, the PC microprocessor (MPU) market finally is set for some real competition though the Intel has been dominated the microarchitecture for more than 30 years.

 “Starting in 1981, when IBM first created its original PC based on Intel’s 8088 microprocessor, the X86 architecture has dominated the PC market,” said Matthew Wilkins, principal analyst of compute platforms for IHS. “Over the next generation, billions of PCs were shipped based on X86 microprocessors supplied by Intel and assorted rivals—mainly Advanced Micro Devices Inc. However, the days of X86’s unchallenged domination are coming to an end as Windows 8 opens the door for the use of the ARM processor, which already has achieved enormous popularity in the mobile phone and tablet worlds.”

However, the ARM processer has to thanks the Windows 8 PC system. To be introduced in 2012, Windows 8 is expected to support ARM-based PC systems in some versions. Microsoft at the Consumer Electronics Show (CES) in January announced that Windows 8 would work with ARM-based system on chip (SoC) designs, whereas the company’s flagship operating system has supported only standalone X86 microprocessors in the past. ARM support will enable the full-fledged Windows PC operating system to work on highly integrated chips that are more space- and power-efficient than traditional X86 microprocessors, such as the ARM devices used in smartphones and media tablets.

When turn to the performance of ARM processors, it said that value notebooks are designed to deliver the optimal price/performance to consumers with a price of less than $700.

 “ARM is well-suited for value notebooks, where performance isn’t a key criterion for buyers,” Wilkins said. “Value notebook buyers are looking for basic systems that balance an affordable price with reasonable performance. ARM processors deliver acceptable performance at a very low cost, along with unrivaled power efficiency.” It is quite an good opportunity to look forward to a growth of PCelectronic componentsunder such conditions.
