Microprocessor

A microprocessor incorporates most or all of the functions of a central processing unit (CPU) on a single integrated circuit (IC). The first microprocessors emerged in the early 1970s and were used for electronic calculators, using BCD arithmetics on 4-bit words. Other embedded uses of 4 and 8-bit microprocessors, such as terminals, printers, various kinds of automation etc, followed rather quickl

These interview questions test the knowledge of x86 Intel architecture and 8086 microprocessor specifically. What is a Microprocessor? - Microprocessor is a program-controlled device, which fetches the instructions from memory, decodes and executes the instructions. Most Micro Processor are single- chip devices.Give examples for 8 / 16 / 32 bit Microprocessor? - 8-bit Processor - 8085 / Z80 / 6800

Microprocessors or commonly known as the central processing unit (CPU). It is the brain of the computer where all programs of the computer system are process and manipulated. It is like a chip in a single Integrated Circuit (IC) which composed of many electronic components that deals with the IC.Early morning, when a man appeared and came to asks some questions about the microprocessors and the co

The CPU is the first thing that comes to mind when many people think about a computer's speed and performance. The CPU is the part of a computer in which arithmetic and logical operations are performed and instructions are decoded and executed. The CPU controls the operation of the computer. Early PCs used several chips to handle the task. Some functions are still handled by support chips, which a

Here’s a peek at the events and technologies that led to the development of Intel’s x86 architecture, plus milestones in its 30-year reign.

Via Technologies, a struggling designer of core-logic sets and x86 central processing units, will reportedly utilize new process technology and introduce processors with two cores by the end of next year. While this will boost competitive position of Via’s chips, the company will still be unable to offer alternative for processors by Advanced Micro Devices [...]

Apple has finally done something with its cash, although spending a tiny part of it, after much speculation of what it would do: it has bought a boutique microprocessor design company called PA Semi. The price, not disclosed, but the story says around $278 million in cash.PA Semi, which is known for its design of sophisticated, low-power chips, could spell a new future for Apple's flagship

The "vocabulary" of instructions which any particular microprocessor chip possesses is specific to that model of chip. An Intel 80386, for example, uses a completely different set of binary codes than a Motorola 68020, for designating equivalent functions. Unfortunately, there are no standards in place for microprocessor instructions. This makes programming at the very lowest level very confusing and specialized. When a human programmer develops a set of instructions to directly tell a microprocessor how to do something (like automatically control the fuel injection rate to an engine), they're programming in the CPU's own "language." This language, which consists of the very same binary codes which the Control Unit inside the CPU chip decodes to perform tasks, is often referred to as

IBM claims to be launched the world's fastest chip for UNIX serversIBM just launched the dual-core 64-bit POWER6 processor running at 4.7 GHz, which doubles the speed of the previous generation POWER5 while using nearly the same amount of electricity to run and cool it.The POWER6 processor is a result of a five-year R&D period, is composed of 790 million transistors and is built using IBM’s 65nm process technology. IBM scientists targeted the way instructions are executed inside the chip to improve performance. For example, in the POWER6, the number of pipeline stages – the chunks of operations that must be completed in a single cycle of clock time – are kept static, but each stage is made faster, removing unnecessary work and doing more in parallel. As a result, execution time is reduced. Earlier this year, IBM hinted that its new POWER6 architecture may hit frequencies higher than 5 GHz. The POWER6 chip has a total cache size of 8 MB per chip – four times the POWER5 chip –
