Interrupts The program enters a wait loop in which it repeatedly tests the device status. During this period, the processor is not performing any useful computation. There are many situations where other tasks can be performed while waiting for an I/O device to become ready. To allow this to happen, we can arrange for the I/O device to alert the processor when it becomes ready. It can do so by sending a hardware signal called an interrupt to the processor. Common classes of interrupts: • Program

development of artificial intelligence in order to put this idea into context. The concept of intelligent and aware constructs began to emerge in the 1950s and 60s as several scientists in many fields came together to discuss the possibilities of advanced computer research. The first major step was a scientific conference at Dartmouth College in 1956. Here, the general concepts and possible paths of research for a.i. were fleshed out. As described in Artificial Intelligence: A Modern Approach, this conference

artificial intelligence The term artificial intelligence or A.I. has been around since the fifties and was conceived by a group of scientists at the Dartmouth College in Hanover New Hampshire. They originally projected they would be able to build a computer that could simulate every feature of human intelligence within thirty years. This obviously has proven very difficult and to have done it in thirty years was impossible. Though we can explain many things about the human race, to explain how the

Electronic Design Automation and the Design of Integrated Circuits Abstract A circuit, simply put, is defined as a complete path around which an electric current can flow in order to complete a predesigned task. Circuit design is the intermediate process by which electrical circuits are moved from the specification stage - where the circuit’s purpose is determined - to the production stage, where all of the information necessary to build a working circuit is ready for implementation. In order

proposed technique achieves power reduction through two mechanisms: 1) power gating the combinational logic within the clock period (subclock) and 2) reducing the virtual supply to less than Vth rather than shutting down completely as is the case in conventional power gating. To achieve this reduced voltage, a pair of nMOS and pMOS transistors are used at the head and foot of the power gated logic for symmetric virtual rail clamping of the power and ground supplies. The subclock power gating technique

what you might not expect is the degree of error necessary to render a financing statement “seriously misleading” under revised Uniform Commercial Code §9-506, thereby rendering it ineffective. The new legal standard, coupled with strict search logic standards being adopted by filing offices are making it much easier to challenge the perfection of a security interest on the basis of minor errors in the debtor’s name. So… "What's in a name? Well, when trying to perfect a security interest under

An Overview of Computer Viruses in a Research Environment Matt Bishop Department of Mathematics and Computer Science Dartmouth College Hanover, NH 03755 ABSTRACT The threat of attack by computer viruses is in reality a very small part of a much more general threat, specifically attacks aimed at subverting computer security. This paper examines computer viruses as malicious logic in a research and development environment, relates them to various models of security and integrity, and examines current
