3. Find the word in the text that best matches with the appropriate
definition.
denoting a computer architecture where several instructions are loaded at once and, as far as possible, are executed simultaneously, shortening the time taken to run the whole program.
the taking away or getting rid of something.
of superior quality or value.
to find out or ascertain something, usually after investigation.
to move or transmit something such as a sound or light wave forward through a medium such as air.
a delay caused when one part of a process or activity is slower than the others and so hinders overall progress.
the belief that something is true without having any proof.
fixed into the surface of something
4. Decide whether the following statements true or false.
Most CPUs are asynchronous in nature.
CPU mustn’t wait on its slowest elements, even though some portions of it are much faster.
Higher clock rates in increasingly complex CPUs make it easier to keep the clock signal in phase throughout the entire unit.
Clock gating involves turning off the clock signal to unneeded components.
The constantly changing clock prevents many components from switching regardless of whether they are being used at the time.
It is clear that totally asynchronous design CPUs can perform at a comparable or better level than their synchronous counterparts.
Unit 8 The integrated circuit
1. Guess the meaning of the following words
Circuit device bonded layer ensure.
2. Read the text and answer the questions after it.
In electronics, an integrated circuit (also known as IC,
microcircuit, microchip, silicon chip, or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive components) that has been manufactured in the surface of a thin substrate of semiconductor material. Integrated circuits are used in almost all electronic equipment in use today and have revolutionized the world of electronics.
Microchips (EPROM memory) with a transparent window, showing the integrated circuit inside. Note the fine silver-colored wires that connect the integrated circuit to the pins of the package. The window allows the memory contents of the chip to be erased, by exposure to strong ultraviolet light in an eraser device.
The idea of an integrated circuit was conceived by a radar scientist working for the Royal Radar Establishment of the British Ministry of Defence, Geoffrey W.A. Dummer (1909-2002), who published it at the Symposium on Progress in Quality Electronic Components in Washington, D.C. on May 7, 1952. Dummer unsuccessfully attempted to build such a circuit in 1956.
The integrated circuit can be credited as being invented by both Jack Kilby of Texas Instruments and Robert Noyce of Fairchild Semiconductor working independently of each other. Kilby recorded his initial ideas concerning the integrated circuit in July 1958 and successfully demonstrated the first working integrated circuit on September 12, 1958.
Kilby won the 2000 Nobel Prize in Physics for his part of the invention of the integrated circuit. Robert Noyce also came up with his own idea of integrated circuit, half a year later than Kilby. Noyce's chip had solved many practical problems that the microchip developed by Kilby had not. Noyce's chip, made at Fairchild, was made of silicon, whereas Kilby's chip was made of germanium.
A hybrid integrated circuit is a miniaturized electronic circuit constructed of individual semiconductor devices, as well as passive components, bonded to a substrate or circuit board.
Synthetic detail of an integrated circuit through four layers of planarized copper interconnect, down to the polysilicon (pink), wells (greyish), and substrate (green).
Integrated circuits were made possible by experimental discoveries which showed that semiconductor devices could perform the functions of vacuum tubes, and by mid-20th-century technology advancements in semiconductor device fabrication. The integration of large numbers of tiny transistors into a small chip was an enormous improvement over the manual assembly of circuits using discrete electronic components. The integrated circuit's mass production capability, reliability, and building-block approach to circuit design ensured the rapid adoption of standardized ICs in place of designs using discrete transistors.
There are two main advantages of ICs over discrete circuits: cost and performance. Cost is low because the chips, with all their components, are printed as a unit by photolithography and not constructed one transistor at a time. Furthermore, much less material is used to construct a circuit as a packaged IC die than as a discrete circuit. Performance is high since the components switch quickly and consume little power because the components are small and close together. As of 2006, chip areas range from a few square millimeters to around 350 mm2, with up to 1 million transistors per mm².
