Shift: Bit shifted out is lost Rotate: Bit shifted out from one end of the destination operand is put back on the other end.

Instruction Set of An instruction is a binary pattern designed inside a microprocessor to perform a specific function. The entire group of instructions that a microprocessor supports is called Instruction Set. What are instruction sets?

Assembly Language

Shift: Bit shifted out is lost Rotate: Bit shifted out from one end of the destination operand is put back on the other end. Performs right shift on destination operand. The effect on flag is same as SHL. If number is even, one right shift is same as divide the number by 2. If number is odd, one right shift halves it and rounds down to nearest integer. Use right shift to divide unsigned number by 4. Put quotient in AX.

This web page examines shift and rotate instructions in assembly language. Specific examples of instructions from various processors are used to illustrate the general nature of assembly language. If you like the idea of this project, then please donate some money. Now building a free emulator and assembly language proigramming lessons. For those with high speed connections, the very large single file summary is still on line. Shift and rotate instructions move bit strings or operand treated as a bit string.

Along with the bitwise instructions, from the previous lectures, shift instructions are among the most characteristic of assembly language.

Ask a Question. In this article, we are going to study another type of instructions of the microprocessor which are used for shifting or rotating the contents of the register. We will first discuss the working of each of these instructions and will then also discuss the syntax for each of them. Submitted by Monika Sharma , on July 29,

Microprocessor - 8086 Instruction Sets

In arithmetic shift right the sign bit most significant bit is shifted into the high-order bit In logical shift right zeros are shifted into the high-order bit Rotate instructions are similar to shift instructions, ecept that rotate instructions are circular, with the bits shifted out one end returning on the other end Rotates can be to. A rotate instruction is a closed loop instruction That is, the data moved out at one end is put back in at the other end The shift instruction loses the data that is moved out of the last bit locations.

 Ничего не выйдет, - пробормотал. В разделе Служба сопровождения в справочнике было только три строчки; впрочем, ничего иного все равно не оставалось. Беккер знал лишь, что немец был с рыжеволосой спутницей, а в Испании это само по себе большая редкость. Клушар вспомнил, что ее звали Капля Росы.

Лифт спускался на пятьдесят ярдов вниз и затем двигался вбок по укрепленному туннелю еще сто девять ярдов в подземное помещение основного комплекса агентства. Лифт, соединяющий шифровалку с основным зданием, получал питание из главного комплекса, и оно действовало, несмотря на отключение питания шифровалки. Стратмору, разумеется, это было хорошо известно, но даже когда Сьюзан порывалась уйти через главный выход, он не обмолвился об этом ни единым словом. Он не мог пока ее отпустить - время еще не пришло.

 Я попросил его не звонить мне, пока он не найдет кольцо. - Почему? - удивилась Сьюзан.  - А если ему нужна помощь. Стратмор пожал плечами.
