Computer System Architecture Handwritten Notes
What is computer architecture system ?
Computer architecture is a specification detailing how a set of software and hardware technology standards interact to form a computer system or platform. In short, computer architecture refers to how a computer system is designed and what technologies it is compatible with.
What is the importance of computer architecture ?
The object of architectural design is to so divide up the functions/actions of the system as to minimize the need for communication which represents a substantial potential point of (design) failure and usually serves as a constraint on future upgrade designs.
Topics in our Computer System Architecture Handwritten Lecture Notes PDF
In these “Computer System Architecture Handwritten Lecture Notes PDF”, we will introduce the students to the fundamental concepts of digital computer organization, design and architecture. It aims to develop a basic understanding of the building blocks of the computer system and highlights how these blocks are organized together to architect a digital computer system.
The topics we will cover will be taken from the following list:
Digital Logic Circuits: Logic Gates, truth tables, Boolean Algebra, digital circuits, combinational circuits, sequential circuits, circuit simplification using Karnaugh map, Don’t Care Conditions, flip-flops, characteristic tables
Digital Components: Half Adder, Full Adder, Decoders, Multiplexers, Registers and Memory Units
Data Representation and Basic Computer Arithmetic: Number system, complements, fixed and floating point representation. Alphanumeric representation. Addition, subtraction.
Basic Computer Organization and Design: Common Bus system, instruction codes, instruction format, instruction set completeness, Sequence Counter, timing and control, instruction cycle, memory reference instructions and their implementation using arithmetic, logical, program control, transfer and input output micro-operations, interrupt cycle.
Central Processing Unit: Micro programmed Control vs Hardwired Control, lower level programming languages, Instruction format, accumulator, general register organization, stack organization, zero-address instructions, one-address instructions, two-address instructions, three address instructions, Addressing Modes, RISC, CISC architectures, pipelining and parallel processing.
Memory Organization and Input-Output Organization: Input-Output Organization: Peripheral Devices, I/O interface, I/O vs. Memory Bus, Programmed I/O, Interrupt-Driven I/O, Direct Memory Access
