Operating System | Assignment #1 | | Information System | 2012-03-29 | | 1. What is the purpose of interrupts? What are the differences between a trap and an interrupt? Can traps be generated intentionally by a user program? If so‚ for what purpose? (Chapter 1) Interrupt is that causes a computer processor to temporarily stop executing its current program and execute another program instead‚ finally returning control to the original program. So it prevent that more important task

The joy of being a computer engineer lies in the amazing ability of complexity synthesis that lies at my disposal. The inexplicable sense of magic‚ which I felt when my first "hello world " got displayed on screen‚ is something I have never experienced in any other phase of my academic pursuit “Hello‚ World”; the first and perhaps the simplest of the programs any novice programmer executes. Yet‚ its seeming simplicity lent a magic-like feeling to programming‚ something that I have found hard to ascribe

A Fast CRC Implementation on FPGA Using a Pipelined Architecture for the Polynomial Division Fabrice MONTEIRO‚ Abbas DANDACHE‚ Amine M’SIR‚Bernard LEPLEY LICM‚ University of Metz‚ SUPELEC‚ Rue Edouard Belin‚ 57078 Metz Cedex phone: +33(0)3875473 11‚ fax: +33(0)387547301‚ email: fabrice.monteiro@ieee.org ABSTRACT The CRC error detection is a very common function on telecommunication applications. The evolution towards increasing data rates requires more and more sofisticated implementations.

binary system was created. Capitalizing on the ground works of the binary system‚ logic gates (transistors) are built to change the states of these signals. By combining logic gates‚ we are able to build complex. The computer processor is one of those units that are made up of thousands of transistors. Since processors are made of logic gates that understand binary‚ it is only natural to feed them with inputs that are in binary formats. In this way‚ no “translation” is need as they are speaking the

Each channel uses the similar trivial handshaking between source and destination (master or slave‚ depending happening channel path)‚ which simplifies the interface design. Unlike AHB concept is not an afterthought but is the central focus of the protocol design. In AXI3 all connections are bursts of lengths between 1 and 16. The addition of byte allow signals for the data bus supports unaligned memory accesses and store merging. The communication between master and slave is
