ReplyDeletewe all know that william shockley was the co-inventor of transistor.After the world war 2 he was employed by bell labs,the telephone company,to head a team trying to find a replacement for the vacuum tubes which is an obsolete device used at that time in computers.
shockley was a man of undoubted brilliance, but also an extremely unpleasant boss.When, in late 1947,his team developed their first transistor,they kept shockley's name off the patent.Shockley responded by locking himself away in a hotel room and within four weeks had designed a more rugged and practical transistor,the predecessor of today's transistor,which switch and amplify in almost every electrical device that exists today.
without shockley's transistor and the digital processors that it spawned there would be no portable computers,no mobile phones,no modern world.

ReplyDeletesir Edwin Hubble:
In 1908 an astronomer from California named George Ellery hale successfully built a telescope with 2.5m mirror at mount Wilson,high in the San Gabriel mountains above Los Angeles which was set to work in 1917.It was named Hooker Telescope after the industrialist.It was known to be the largest telescope in those days.
At that time the hooker telescope came into action it was still a mater of debate as to whether or not the universe extended beyond the milky way.Hale had hired a young astronomer called Edwin Hubble to work on the "100-inch" telescope and in 1923 Hubble observed a special kind of star,called a Cepheid variable,whose luminosity varies in a precisely known way such that its brightness or dimness can be used to provide a measure of how far it is,it was in the nebulae of Andromeda.
Hubble did not stop there.In 1924 Hubble measured the distance to the Andromeda nebula, a faint patch of light with about the same apparent diameter as the moon, and showed it was about a hundred thousand times as far away as the nearest stars. It had to be a separate galaxy, comparable in size our own Milky Way but much further away.Suddenly,the universe was even more wast than had been believed.
Hubble was able to measure the distances to only a handful of other galaxies, but he realized that as a rough guide he could take their apparent brightness as an indication of their distance. The speed with which a galaxy was moving toward or away from us was relatively easy to measure due to the Doppler shift of their light. Just as a sound of a racing car becomes lower as it speeds away from us, so the light from a galaxy becomes redder. Though our ears can hear the change of pitch of the racing car engine our eyes cannot detect the tiny red-shift of the light, but with a sensitive spectrograph Hubble could determine the redshift of light from distant galaxies.
The observational data available to Hubble by 1929 was sketchy, but whether guided by inspired instinct or outrageous good fortune, he correctly divined a straight line fit between the data points showing the redshift was proportional to the distance.
Today his name carried by the best telescope we have, not on Earth, but a satellite observatory orbiting our planet. The Hubble Space Telescope is continuing the work begun by Hubble himself to map our Universe, and producing the most remarkable images of distant galaxies ever seen.These images from the farthest reaches of the visible universe continue to amaze us all and show us,quite literally,what is out there.

ReplyDeleteBAIRD, JOHN LOGIE
"John Logie Baird (1888-1946) was a Scottish inventor and engineer who was a pioneer in the development of mechanical television. In 1924, Baird televised objects in outline. In 1925, he televised human faces. In 1926, Baird was the first person to televise pictures of objects in motion. In 1930, Baird made the first public broadcast of a TV show, from his studio to the London Coliseum Cinema; the screen consisted of a 6-ft by 3-ft array of 2,100 tiny flashlamp bulbs. Baird developed a color television in 1928, and a stereo television in 1946. Baird's mechanical television was usurped by electronic television, which he also worked on"...
AT A GLANCE:
ReplyDelete"Today's communications industry would not be what it is without the contributions made by Richard H. Frenkiel and Joel S. Engel. The big breakthrough came when AT&T Labs researchers Frenkiel and Engel divided wireless communications into a series of cells, then automatically switched callers as they moved so that each cell could be reused. This led to the development of cellular phones and made today’s mobile communications possible. "

The Plastic Processor
ReplyDeleteEuropeans announce the first organic microprocessor
Take a bow, flexible chip. This week at the International Solid-State Circuits Conference, in San Francisco, European researchers will introduce the world’s first microprocessor made with organic semiconductors. The 4000-transistor, 8-bit logic circuit has the processing power of only a 1970s-era silicon model, but it has a key advantage—it can bend. The device’s designers say the chip could lead the way to cheaper flexible displays and sensors. Wrapped around pipes, for example, sheets of sensors with these processors could record average water pressure, and wrapped around food and pharmaceuticals, they might indicate that your tuna is rancid or that you forgot to take your pills.

The world better knows Vinod Dham as the father of the Pentium processor, a man who helped revolutionize computer technology. Today 90% of the world's computers run on Pentium chips.
ReplyDeletePune born Dham worked in the memory design group at the National Cash Register (NCR), Ohio. His big break came during a presentation on his numerous patents, when he received an offer from Intel to work with them. The rest is history. His invention-the 586 or Pentium processor became a hit worldwide.
Dham became the vice president of Intel's Microprocessor Products Group. However, after quitting Intel in 1995, he joined NexGen, as CEO and Executive VP of the startup. When AMD acquired NexGen in 1996, Dham looked after the development of AMD's famous K6 Processor, the world's fastest personal computer microprocessor. Presently, he is chairman, president and CEO of Silicon Spice, a communications technology development firm.
maths trick
ReplyDelete1. The 11 Times Trick
We all know the trick when multiplying by ten – add 0 to the end of the number, but did you know there is an equally easy trick for multiplying a two digit number by 11? This is it:
Take the original number and imagine a space between the two digits (in this example we will use 52:
5_2
Now add the two numbers together and put them in the middle:
5_(5+2)_2
That is it – you have the answer: 572.
If the numbers in the middle add up to a 2 digit number, just insert the second number and add 1 to the first:
9_(9+9)_9
(9+1)_8_9
10_8_9
1089 – It works every time.

about FPGAs:
ReplyDeleteYou might have heard of FPGAs recently in all different industries. And being curious as to what FPGAs actually are, how they work. Well, FPGA stands Field Programmable Gate Array and it’s basically just a silicon chip that has a reprogrammable digital circuitry. And so each of these FPGAs has a number of configurable logic blocks. There’s up to 1000s of these logic blocks in any given FPGA. And between them, you have reconfigurable wiring circuitry, so you can basically configure these logic blocks in any given configuration for whatever application you need and so you have dedicate hardware logic for any given task and you can dedicate certain sections of an FPGA tip to that particular task. So, you can imagine I can have my digital logic in one part of the chip configured to do something whereas I can have a completely different task running with true parallel operation configured in a whole different part of the chip. So this could be important for single point control applications for example where I have I/O pins on my FPGA to interface each of these digital circuit blocks with the outside world And so I can drive this top circuit with an analog signal. So imagine I have some analog single like in run mat to an analog to digital convertor and I can drive that analog signal directly into the chip and perhaps I want to do some kind of signal processing maybe some filtering for example where I could then take my filtered signal and send that to one of the output pins, a digital to analog converter for example and send that filtered signal then to the outside world. It might make more sense if we use more real world applications. So, let’s say I wanted to monitor the temperature of something and control that temperature, well, I can have a temperature sensor running somewhere and I can take that analog voltage signal and send that into the FPGA and to be a little more specific, my digital logic block can actually be a PID controller. Those of you that are doing PID control will be very familiar with a PID controller where you have some analog signal or some basically some measured sensor signal and you can then compare that sensor to some desired value and based on the difference between those, you can output something to actuate that temperature and so in this case I can send it to a fan for example. And so if I wanted to decrease the temperature, well I could do that basically by speeding up the fan and making the fan go faster, I can read the temperature again and do that over and over again. Well that control loop speed is very important and if I wanted to do multiple control loops, I could dedicate different parts of the FPGA chip and section those of as well. So, I can have multiple PID loops running truly in parallel. This is very different to a processor based system which is something that you might already be familiar with. a processor based system or a CPU is also a silicon chip except instead of running things with dedicated blocks for any given task, your operating system figures out how to sequentially come up with the list of instructions. And then the processor just takes turns executing each function one at a time. So inherently a processor is very good at doing many different things all at the same time by sequentially executing an instruction set whereas an FPGA has dedicated blocks of silicon which are given running independently and not necessarily sharing resources for any given task. So that should give you a brief introduction to how FPGAs work and how you get true re-configurability with hardware timed speed and true parallel operation for any given application.
TIME LINE OF MICRO PROCESOR:
ReplyDeleteThe seventies were a good time for intel, mostly because they were the first players in the game. Motorola jumped in rapidly thereafter, however, and brought out the ubiquitous 6800 and later the even more important 68000 during the same timeframe. Even today, however, 808x CPUs are more popular in embedded systems than the more powerful Motorola 68000, if for no other reason than inertia. Intel got there first, and got the ball rolling. A great deal of their installed base comes from the fact that the IBM PC and every clone of it thereafter carried an intel CPU.
IBM also invented the first RISC CPU during this decade (barely). They began work on it way back in 1975. That chip was never released but concepts in its design made it all the way into the PowerPC by way of ROMP and then POWER.
1971: 4004 (intel) Used in the Busicom calculator. First microprocessor. 4 bits, 2300 transistors, 740 kHz, 0.06 MIPS.
1972: 8008 (intel) Used in the Mark-8.
1974: 8080 (intel) Used in the Altair.
1974: MC6800 (Motorola) Easier to implement than intel 8080 as it needs only one voltage and no support chips to operate. Mostly sold for peripheral and industrial control.
1975: MC6501 (MOS) Pin-compatible with Motorola MC6800, leading to a lawsuit against MOS.
1975: MC6502 (MOS) Replaces the 6501, and is not pin-compatible with MC6800. Used in Apple 2 and Commodore VIC 20. MOS Technology was purchased by Commodore later the same year.
1976: 8085 (intel) Improved version of the 8080; uses only +5V, where 8080 needs several voltages, and with additional instructions as well.
1976: TMS9900 (TI) First 16 bit microprocessor.
1976: Z80 (Zilog) The Z80's instruction set is a superset of the intel 8080. It later becomes one of the most ubiquitous embedded processors of all time. The de facto standard for computers running CP/M. Also featured in the Radio Shack TRS-80 and the Nintendo Game Boy, among many others.
1978: 8086 (intel) Used (later) in the IBM PC. Also, the complementary 8087 math coprocessor.
1979: 8088 (intel) Cost reduced 8086, with an 8 bit bus instead of 16 bit.
1979: 801 (IBM) First RISC CPU made. Never commercialized.
1979: Z8000 (Zilog) 16 bit chip.
1979: MC68000 (Motorola) 16 bit processor with 24 bit addressing.
