Microprocessor Interview Questions and Answers 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. What are the flags in 8086? In 8086 Carry flag‚ Parity flag‚ Auxiliary carry flag‚ Zero flag‚ Overflow flag‚ Trace flag‚ Interrupt flag‚ Direction flag‚ and Sign flag. Why crystal is a preferred clock source? Because of high stability‚ large

Case Analysis Most of the world’s PCs are powered by an Intel microprocessor. It is recognized as one of the most valuable brand in the world. Through high levels of investment and concentrating on microprocessors‚ Intel was able to leave competitors behind. Intel’s new strategy moves away from just the production of microprocessors‚ to producing platforms integrated sets of technology that work together. Intel the Microprocessor giant was started in the year 1968‚ their initial venture was to

The Pentium Flaw NT1110 Computer Structure and Logic Unit 2 Analysis The Pentium floating-point unit flaw only occurred on some models of the original Pentium microprocessor chip. Any of the Pentium family processors with a clock speed of at least 120 MHz is new enough not to have the bug. On the affected microprocessor models‚ the Intel Processor Frequency ID Utility checks for the floating-point unit flaw. Professor Thomas Nicely sent an email describing the flaw that he had discovered

The 8085 includes five flip-flops‚ also called flags‚ which are set or reset after an operation according to data conditions of the result in the accumulator and other registers. They are called Zero (Z); carry (CY)‚ Sign(S)‚ Parity (P) and Auxiliary Carry (AC) flags. And the most commonly used flags are Zero‚ Carry‚ and

is stopping the thing or person from their normal course of action. This is the same in the case of a microprocessor too. The Intel 8085 microprocessor has this feature called the Interrupt which enables the user to stop the execution of a current action for a specified interval of time. Using this Interrupt feature one can pause the current sequence of actions being executed by the microprocessor to make it execute some other action. The interrupt I/O is a process of data transfer whereby

What threats has Intel faced in sustaining its competitive advantage in microprocessors and what strategies has it used to deal with each? Why has Intel been able to sustain its advantage in microprocessors‚ but not in DRAMs? In the early microprocessor arena‚ only two companies had the ability to produce microprocessors that could be used for PCs – Motorola and Intel. Intel’s strategy was based on beating

The history of computer development is often referred to in reference to the different generations of computing devices. A generation refers to the state of improvement in the product development process. This term is also used in the different advancements of new computer technology. With each new generation‚ the circuitry has gotten smaller and more advanced than the previous generation before it. As a result of the miniaturization‚ speed‚ power‚ and computer memory has proportionally increased
