    This interrupt takes the form of a memory address of code needed to handle the interrupt (in this case print a file). Alternatively a simple pulse can be sent over the signal line. This results in additional processing for the CPU prior to step 4 to pole the devices and find the one responsible. In this case the device id becomes a pointer to an array containing the address of the event handler for that device (Zaks,1980, p. 506). 3. When the CPU receives the interrupt it suspends processing

    Problem Set Exercise 1 1. An interrupt is used by device controller to inform the CPU that the operation by Device controller is finished. In general, an occurrence of any event can be signaled by interrupt, from hardware or software. 2. A trap, also called interrupt, is generated from the software, due to an error or a user request. 3. A multiprogramming is used to keep the CPU busy most of the time, i.e. increase utilization of system CPU. This is due to the fact that multiprogramming is performed

    which handles the software and hardware and all of computer 's memory and processes. Every part of main memory, every file and processes is controlled by an OS An operating systems includes four essential subsystem managers; • Memory Manager • Processor Manager • Device Manager • File Manager These managers monitor their resources continuously which handles the scheduling processes during which they de-allocate and allocate the resources. Users can directly interact with the operating system through

    architecture for heterogeneous multicore machines that communicate with message passing only. Explicit inter-core communication, hardware-neutral structure and state is replicate not shared, these are the design principles of multikernel. The advantages of these principles are: improve performance, supporting core heterogeneity, modularity, and reuse the algorithms of distributed systems. 3.1 Make inter-core communication explicit Using explicit communication will help to use the system interconnect in

    You can’t know where you’re going unless you know where you been, this saying rings true when thinking of Lunix. In order to know the start of Lunix one would have to travel back in time quite a bit. In this paper, I will research the start of Linux, the growth, and the future. When thinking of computers imagine they are as big as the tallest building or stadium. While the size of those computers posed problems, there was the one thing that made them worse: every computer had a different operating

    developers to take advantage of known address locations. Windows address space can be larger or smaller than the actual memory installed on the machine. Windows handles memory management with two responsibilities. The primary is to map or translate the processors virtual address space to the physical memory. The second responsibility is to manage the swap file between the hard drive and Random Access Memory (RAM). Windows memory management also includes memory mapped files. Allowing files to be placed into

    In this paper a project is proposed to separate the objects from a set according to their colors. This can be useful for categorization of the objects which move on a conveyer belt. The proposed method of categorization is based on color of the object. In this project the system categorization of different colors. The detection of the particular color is done by a light intensity to frequency converter method. The robotic arm is controlled by a microcontroller based system which controls DC motor

    to easily increase code coverage. This project describes the use of coverage driven verification for Avalon Memory Mapped Interface VIP using UVM methodology. The Avalon bus is a simple bus architecture which makes the connection between on-chip processors and peripherals together into a SOPC. It is an interface that specifies the port connections between master and slave components, and also specifies the timing by which these components communicate. Avalon Memory-Mapped (Avalon-MM) interfaces can
