Amazing!!!!!! 100 x 0.5 cores=cloud computing

Amazing!!!!!! 100 x 0.5 cores=cloud computing 36-core tile Gx 3000

Tilera's Tile-Gx family introduced the 100 core, 64-bit VLIW architecture but the chips where heavily loaded for high end communication chores.

The new Gx 3000 series builds on the same architecture but cuts power consumption and reduces the Ethernet port count to deliver a chip that is ideal for the cloud. Each 1.5 GHz 64-bit VLIW core draws less than 0.5W cutting power by 80%. The chips still incorporate a wire-speed packet engine delivering 40 Gbit/s throughput. Likewise, the MiCA engines include 20 Gbit/s crypto support and they can compress/decompress packets at 10 Gbits/s.

The 36-core chip (Fig. 1) is available now and the 100-core chip will be available later this year.

Tilera's iMesh network actually implements a parallel set of interconnects. One network handles cache coherency for Tilera's DDC (Dynamic Distributed Cache) while others handle memory and communication operations. The mesh also provides TileDirect coherent I/O support. Each core has a mesh switch node associated with it.

The VLIW cores support virtualization and have DSP and SIMD instructions that can be very handy for embedded applications. The architecture supports hardware parititioning so groups of cores can provide isolated computing islands. The system also provides Zero-Overhead Linux (ZOL) support. Essentially ZOL is a tickless Linux environment that is very handy for efficient packet processing.

Tilera's Eclipse-based open source IDE, Multicore Development Environment (MDE) provides a standard set of compilers and debuggers. Tilera also provides advanced debugging and profiling tools for the Gx 3000 Series.

The Newest Processor : Intel Core i7



Intel Corporation (NASDAQ: INTC; SEHK: 4335; Euronext: INCO) is the inventor of the x86 series of microprocessors, the processors found in most personal computers. The company is the world's largest semiconductor chip maker, based on revenue. Intel was founded on July 18, 1968, as Integrated Electronics Corporation (though a common misconception is that "Intel" is from the word intelligence) and is based in Santa Clara, California, USA. Intel also makes motherboard chipsets, network interface controllers and integrated circuits, flash memory, graphic chips, embedded processors, and other devices related to communications and computing. Founded by semiconductor pioneers Robert Noyce and Gordon Moore, and widely associated with the executive leadership and vision of Andrew Grove, Intel combines advanced chip design capability with a leading-edge manufacturing capability. Originally known primarily to engineers and technologists, Intel's "Intel Inside" advertising campaign of the 1990s made it and its Pentium processor household names.

Intel was an early developer of SRAM and DRAM memory chips, and this represented the majority of its business until the early 1980s. While Intel created the first commercial microprocessor chip in 1971, it was not until the success of the personal computer (PC) that this became their primary business. During the 1990s, Intel invested heavily in new microprocessor designs fostering the rapid growth of the PC industry. During this period Intel became the dominant supplier of microprocessors for PCs, and was known for aggressive and sometimes controversial tactics in defense of its market position, particularly against AMD, as well as a struggle with Microsoft for control over the direction of the PC industry. The 2009 rankings of the world's 100 most powerful brands published by Millward Brown Optimor showed the company's brand value rising 4 places – from number 27 to number 23.

Processor Intel Core i7

Intel Core i7 is Intel's brand name for several families of desktop and laptop 64-bit x86-64 processors using the Intel Nehalem microarchitecture.

It is a successor to the Intel Core 2 brand. The Core i7 identifier was first applied to the initial family of processors codenamed Bloomfield introduced in 2008. In 2009 the name was applied to Lynnfield and Clarksfield models. Prior to 2010, all models were quad-core processors. In 2010, the name was applied to dual-core Arrandale models, and the Gulftown Core i7-980X Extreme processor which has six hyperthreaded cores.

Intel representatives state that the moniker Core i7 is meant to help consumers decide which processor to purchase as the newer Nehalem-based products are released in the future.[8] The name continues the use of the Intel Core brand. Core i7, first assembled in Costa Rica, was officially launched on November 17, 2008[11] and is manufactured in Arizona, New Mexico and Oregon, though the Oregon (PTD, Fab D1D) plant has already moved to the next generation 32 nm process.

Processor Cores

The initial Core i7 processors released were codenamed Bloomfield, branded as Core i7-9xx along with their Xeon 3500-series counterparts. As of 2009, they are Intel's high-end Desktop processors, sharing the Socket 1366 platform with the single and dual-processor server processors.

Lynnfield is the second processor sold under the Core i7 brand, while at the same time being sold as Core i5. Unlike Bloomfield, it does not have a QPI interface but directly connects to a southbridge using a 2.5 GT/s Direct Media Interface and to other devices using PCI Express links in its Socket 1156. Core i7 processors based on Lynnfield have Hyper-Threading, which is disabled in Lynnfield-based Core i5 processors.

Clarksfield is the mobile version of Lynnfield and available under the Core i7 Mobile brand, as part of the Calpella platform. It was released at the Intel Developer Forum on September 23, 2009.

The second mobile Core i7 processor family will be Arrandale, sold as the Core i7-6xx processors and featuring an integrated graphics processing unit but only two processor cores, half of Clarksfield. Clarkdale, the desktop version of Arrandale, will not be sold as Core i7, but only as Core i3 and Core i5. All support Intels Hyper Threading (HT).

Gulftown is the Extreme Edition version of the Core i7, featuring 6 cores, 32nm process, Hyper-Threading (for a total of 12 logical threads), 12 MB of cache, Turbo Boost and Intel QuickPath connection bus

DNA Computer can store billions of times more information then your PC hard drive and solve complex problems in a less time. We know that computer chip manufacturers are racing to make the next microprocessor that will more faster. Microprocessors made of silicon will eventually reach their limits of speed and miniaturization. Chips makers need a new material to produce faster computing speeds.

To understand DNA computing lets first examine how the conventional computer process information. A conventional computer performs mathematical operations by using electrical impulses to manipulate zeroes and ones on silicon chips. A DNA computer is based on the fact the information is “encoded” within deoxyribonucleic acid (DNA) as patterns of molecules known as nucleotides. By manipulating the
how the nucleotides combine with each other the DNA computer can be made to process data. The branch of computers dealing with DNA computers is called DNA Computing.

The concept of DNA computing was born in 1993, when Professor Leonard Adleman, a mathematician specializing in computer science and cryptography accidentally stumble upon the similarities between conventional computers and DNA while reading a book by James Watson. A little more than a year after this, in 1994, Leonard M. Adleman, a professor at the University of Southern California, created a storm of excitement in the computing world when he announced that he had solved a famous computation problem. This computer solved the traveling salesman problem also known as the “Hamiltonian path" problem, which is explained later. DNA was shown to have massively parallel processing capabilities that might allow a DNA based computer to solve hard computational problems in a reasonable amount of time.

RGM-3550LP GPS module connected with Asus Eee pc

rgm-3550lp-gps-modules-connected-with-asus-eee-pc

The idea behind this project was born when a friend asked me too take a look at he’s broken GPS unit (MyGuide 3000) to see if I can fix anything. I started checking various parts like voltage regulators, but found nothing wrong. The gps unit was still not powering up so I checked the cpu, an ARM9 from Samsung and found it broken. Of course I couldn’t do anything about that, because of the BGA package and the bootloader needed after replacing it so the gps unit became a source for parts. The most useful and interesting parts from the GPS were the LCD display and the GPS module.

The GPS module is a RoyalTek RGM-3550LP which has an integrated antenna and is powered by SiRF Star III technology. I immediately connected the gps module to my computer’s serial port(using a max232) to test if it was still working. To my surprise the gps module was working and sending NMEA compliant sentences. Then I had this idea of using the gps module as a navigation system together with a notebook computer, but notebooks don’t have a serial port so I had to use a UART to USB bridge.

RoyalTek rgm-3550lp-gps-module

The most common used UART-USB bridge is the FT232 manufactured by FTDI which is about $4 which is a fair price because you don’t need any external parts for this chip except some bypass capacitors and that saves you time and money. I never used the chip before but it was really easy to get it working. It even has this custom utility that let’s you program some features saved in the internal EEPROM like the maximum bus power and the product and manufacturer descriptor strings. Anyway these are the only two settings that I tinkered with, but the utility let’s you change some more stuff.

ft232rl-usb-uart-bridge

The next thing I had to worry was where to get the power for the GPS unit, because it needs 3.3V and the acquisition current is 50 mA. The FT232 has an internal voltage regulator which provides 3.3 V and 50 mA but I decided not to use that in order to extend it’s life so I ended up using the TPS2148 which is a 3.3V LDO from Texas Instruments. It’s specifically designed for USB peripheral power management, and it’s tiny package(MSOP-8) made it ideally for my application. The TPS2148 handles the current limitation so I didn’t had to worry about that either.

tps2148-msop-8-package

After figuring out the parts I was going to use and the schematic, I had to chose an enclosure for this project. The main target was to get it as small as possible but the limit was the gps module size, I couldn’t of got it smaller then the module :) . So I went and searched for a plastic enclosure, and I found one just perfect for what I needed, the PP85D from Supertronic. The gps module fits just nicely between the screw channels.

Then after I got the enclosure, I made the pcb using the photo etching technique.. I assembled and tested it, and to my surprise everything worked just fine from the first try. I’m usually not that lucky when I make stuff using new IC’s that I haven’t used before. Sometimes I don’t pay enough attention to the datasheet and I get some small stuff left behind and that messes my entire circuit. Anyway, happy as I was that everything worked from the first try, I put everything inside the enclosure and snapped some pictures of it. As a final note, this was a great project which I enjoyed making, and I really recommend you do something like this if you have a gps unit laying around.
