Computer Organization And Architecture By Zaky Pdf To Word
DescriptionThis video tutorial provides a complete understanding of the fundamental concepts of Computer Organization. The tutor starts with the very basics and gradually moves on to cover a range of topics such as Instruction Sets, Computer Arithmetic, Process Unit Design, Memory System Design, Input-Output Design, Pipeline Design, and RISC. In addition, the tutor has solved a number of GATE problems related to Computer Organization to reinforce the concepts. AudienceThese video classes have been developed based on the latest GATE syllabus and will be useful for undergraduate students of Computer Science and Information Technology as well as those preparing for GATE exams. It will also be helpful for students in preparing them for their Engineering Syllabus. Corporate TrainerProf. Arnab Chakraborty is a Calcutta University alumnus with B.Sc.

The basic computer has 16-bit instruction register (IR) which can denote either memory reference or register reference or input-output instruction. Memory Reference – These instructions refer to memory address as an operand. The other operand is always accumulator. Specifies 12-bit address, 3-bit opcode (other than 111) and 1-bit addressing mode for direct and indirect addressing.Example –IR register contains = 0001XXXXXXXXXXXX, i.e. ADD after fetching and decoding of instruction we find out that it is a memory reference instruction for ADD operation.
Hence, DR ← MARAC ← AC + DR, SC ← 0. Register Reference – These instructions perform operations on registers rather than memory addresses. The IR(14 – 12) is 111 (differentiates it from memory reference) and IR(15) is 0 (differentiates it from input/output instructions). The rest 12 bits specify register operation.Example –IR register contains = 000000, i.e. CMA after fetch and decode cycle we find out that it is a register reference instruction for complement accumulator.
Hence, AC ← AC. Input/Output – These instructions are for communication between computer and outside environment. The IR(14 – 12) is 111 (differentiates it from memory reference) and IR(15) is 1 (differentiates it from register reference instructions). The rest 12 bits specify I/O operation.Example –IR register contains = 000000, i.e. INP after fetch and decode cycle we find out that it is an input/output instruction for inputing character.
