Von Neumann Architecture
The document summarizes the Von Neumann architecture, which is a design model for stored programs. It describes the key components of the architecture including the input/output subsystem, central processing unit (CPU), arithmetic logic unit (ALU), control unit, and main memory. The CPU is where computations take place via four main functions: fetch, decode, execute, and write back. The ALU performs arithmetic and logic operations while the control unit coordinates activity within the CPU. The main memory is divided into volatile RAM and non-volatile ROM for temporary and permanent storage.
Basic+machine+organization
Computer architecture consists of instruction set architecture (ISA), which is software, and machine organization, which is hardware and design. The basic machine organization includes a CPU with an ALU and control unit, memory subsystem to store data, and I/O subsystem connecting to devices. These components communicate through buses - the address bus specifies memory locations, the data bus transfers data, and the control bus sends signals. The CPU follows an instruction cycle of fetching, decoding, operand fetching, executing instructions, and writing back results through the buses to memory or I/O.
Basic computer organization
This document discusses the basics of computer organization including the stored program concept, how main memory is organized, and the input/output system. It explains that computers are based on the stored program design with a CPU and memory that manages the fetch-decode-execute instruction cycle to coordinate other devices. Memory is divided into words that each have a unique address for storage and retrieval of binary data and instructions. The document also outlines the fetch-decode-execute cycle and types of operations computers can perform like data movement, arithmetic, and program control.
I/O Management
The document provides information about input/output management in operating systems. It discusses I/O devices, device controllers, direct memory access and DMA controllers. Some key points include:
I/O devices are divided into block devices which access fixed size blocks of data and character devices which access data as a sequential stream. Device controllers act as an interface between devices and device drivers. Direct memory access allows data transfer between memory and devices without CPU involvement by using a DMA controller. DMA controllers program data transfers and arbitrate bus access.
Central processor amd memory
The document discusses the central processing unit (CPU) and memory in a computer system. It describes the CPU as having a control unit that oversees operations and an arithmetic logic unit (ALU) that performs calculations. The document defines primary memory (RAM) for temporary storage and secondary storage (hard disks and USB drives) for permanent storage. It also lists several ways to increase processing speed, such as using a faster system clock, wider data buses, larger word sizes, more cache memory, and parallel processing.
N301 Von Neumann Architecture
The document discusses the von Neumann architecture, which is still the fundamental design of modern computers.

For students wk4_computer_function_and_interconnection
This chapter discusses the top-level view of computer function and interconnection. It explains that a program is a sequence of steps and operations that are executed through different control signals. The central processing unit consists of a control unit and arithmetic logic unit. Data and instructions are input and output through input/output components, while temporary storage is provided by main memory. The computer components are interconnected through buses that transfer data, addresses, and control signals between the CPU, memory, and input/output devices.
Basic computer architecture
This document provides an overview of basic computer architecture and components. It discusses the history of computers and introduces Arduino.

The von Neumann and Harvard CPU architectures are explained. The CPU has three major components: the ALU, CU, and registers. Memory types like RAM, ROM, cache memory and their functions are also summarized.
Buffers and spoolers
A buffer is an area of computer memory that stores data temporarily between a fast system component and a slower peripheral device, such as between a processor and printer. This ensures the processor is not held up by the slower speeds of peripherals. Buffers also track the status of peripherals so the processor knows when data can be sent or received. Similarly, spoolers send data to fast hard disk storage before transmitting to peripherals, allowing users to continue working while data sends in the background, which is preferable for large data transfers or shared network peripherals.

Wk 4 top_level_view_of_computer_function_and_interconnection
This document summarizes key points from Chapter 3 of William Stallings' book "Computer Organization and Architecture". It discusses the top-level view of computer function and interconnection. The main components of a computer are the control unit, arithmetic logic unit, main memory, and input/output. Programs are sequences of steps that are executed via control signals. Buses are used to connect these components and transfer data, addresses, and control signals. Interrupts allow other devices to interrupt normal program execution.
Computer architecture
The document summarizes the key components of a CPU: RAM, registers, buses, ALU, and control unit. It describes how these components work together, such as how the control unit controls instruction flow. The document also discusses the von Neumann architecture and how modern computer architecture remains similar with multiple CPUs connected to memory via buses. Lastly, it defines the fetch-execute cycle as the basic operation of a computer receiving an instruction and carrying out the required action.
I/O Buffering
Buffer is an area of memory used to temporarily store data during transfer between two devices or between a device and an application. There are several types of buffering used in operating systems:
1) Single buffering uses one buffer assigned by the OS for each I/O request.
2) Double buffering uses two system buffers so computation and transfer can occur in parallel.
3) Circular buffering uses more than two buffers arranged in a circle so I/O can keep up with rapid process bursts.
4) Utility buffering overlaps I/O with computations through reserving memory areas called buffers. This improves CPU utilization and job completion times.
DEVICE FILE AND INPUT OUTPUT SUBSYSTEMS MANAGEMENT
1) A device manager, either inside or outside the kernel, coordinates communication between applications, drivers, and devices by managing I/O requests and interrupt queues.
2) The device manager creates a kernel interface and API to control devices by activating their register-specific actions.
3) Device management involves polling, interrupts, and DMA and supports various I/O approaches including programmed, interrupt-driven, and DMA-driven I/O.
Computer architecture
This document provides an overview of the history and development of computer architecture. It begins with some of the earliest computing devices like the abacus and ENIAC, the first general-purpose electronic digital computer. It then discusses the evolution of CPU and memory architecture from vacuum tubes to integrated circuits and microprocessors. The document outlines different bus architectures like ISA, EISA, MCA, PCI, and AGP that were used to connect components. It also reviews memory hierarchies and I/O interfaces like IDE, SCSI, serial ports, USB, and parallel ports. The presentation aims to trace the progression of computer hardware technology over time.
Computer system architecture
The document discusses different types of computer system organizations based on the number of general-purpose processors used: single-processor systems which use one main CPU, multiprocessor/multicore systems which contain two or more closely communicating processors, and clustered systems which gather multiple complete computer systems together. Single-processor systems may contain additional special-purpose processors like disk or keyboard controllers. Multiprocessor systems can be symmetric, with all processors performing all tasks, or asymmetric with dedicated tasks. Clustered systems provide high-availability and parallel processing across nodes.
Memory hierarchy
The document discusses the memory hierarchy in computers. It explains that main memory communicates directly with the CPU, while auxiliary memory devices like magnetic tapes and disks provide backup storage. The total memory is organized in a hierarchy from slow but high-capacity auxiliary devices to faster main memory to an even smaller and faster cache memory. The goal is to maximize access speed while minimizing costs. Cache memory helps speed access to frequently used data and programs.
Computer system architecture
The document summarizes the Von Neumann architecture, which was proposed by John von Neumann in 1945. It consists of four main components: a memory to store both instructions and data, a processing unit to perform arithmetic and logical operations, a control unit to interpret instructions, and a bus connecting the components. This architecture is used in most modern computers but suffers from the Von Neumann bottleneck due to the shared bus, which limits throughput between the CPU and memory. Mitigation techniques include using caches, separate memory paths for data and instructions, and on-chip scratchpad memory.

Embedded systems contain processors designed to perform dedicated functions. They tightly integrate hardware and software to perform tasks like controlling quadcopters, engines, and satellites. Embedded systems have processors unlike general purpose CPUs in PCs. They are integral parts of larger systems. Microcontrollers are commonly used embedded systems that integrate a processor, memory, and I/O on a single chip. They include peripherals like timers, analog-to-digital converters, and communication protocols. The microcontroller acts as the brain that processes instructions from memory and transfers data through buses to peripherals and memory to control inputs and outputs.
