Question

What is an instruction in the context of a Microprocessor? How does a
microprocessor instruction specify data and operations? Explain with the
help of an example.

Answer 1

To understand how a microprocessor works, it is helpful to look inside and learn about the logic used to create one. In the process you can also learn about assembly language -- the native language of a microprocessor -- and many of the things that engineers can do to boost the speed of a processor.

A microprocessor executes a collection of machine instructions that tell the processor what to do. Based on the instructions, a microprocessor does three basic things:

Using its ALU (Arithmetic/Logic Unit), a microprocessor can perform mathematical operations like addition, subtraction, multiplication and division. Modern microprocessors contain complete floating point processors that can perform extremely sophisticated operations on large floating point numbers.A microprocessor can move data from one memory location to another.A microprocessor can make decisions and jump to a new set of instructions based on those decisions.

Answer 2

MICROPROCESSOR

A microprocessor is a digital electronic device in which millions of transistors are designed using integrated circuits as integrated circuits or ICs. This also serves as the CPU or CPU, the central processing unit of the computer. The invention of integrated circuits was the way forward for the creation of a microprocessor.

Before microprocessors came into existence, CPUs were built by connecting individual electronic components or by circuits with small-scale integration. The first microprocessor was built in the 1960s. It was then used to compute binary coded decimal BCD in electronic calculators. Later, 6 and 7 bit microprocessors were used in terminals, printers and automation devices.

There are mainly two large microprocessor manufacturing companies in the world - Intel INTEL and AMD. Among these, processors of Intel company are used more. Each company gives different code names according to the technology and capacity of the processors, such as Intel's main processors are Pantium 1, Pantium 2, Pantium 3, Pantium 4, Celeron, Core to Duo etc. Amd The major processors of the company are K-5, K-6, Athelon etc.
