    This book is a hands-on introduction to the principles and practice of embedded system design using the PIC microcontroller. Packed with helpful examples and illustrations, it gives an in-depth treatment of microcontroller design, programming in both assembly language and C, and features advanced topics such as networking and real-time operating systems. It is accompanied by a CD-ROM containing copies of all programs and software tools used in the text and a `student version of the C complier Designing Embedded Systems with PIC Microcontrollers: Principles and Applications is ideal for students of electronics, mechatronics and computer engineering. Engineers in industry and informed hobbyists will also find this book a valuable resource when designing and implementing both simple and sophisticated embedded systems using the PIC Microcontroller.

  • The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowled

    The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowledge of the elements of arithmetic as they exist on a computer. That conclusion and this book are the result of a long and frustrating search for information on writing arithmetic routines for real-time embedded systems. With instruction cycle times coming down and clock rates going up, it would seem that speed is not a problem in writing fast routines. In addition, math coprocessors are becoming more popular and less expensive than ever before and are readily available. These factors make arithmetic easier and faster to use and implement. However, for many of you the systems that you are working on do not include the latest chips or the faster processors. Some of the most widely used microcontrollers used today are not Digital Signal Processors (DSP), but simple eight-bit controllers such as the Intel 8051 or 8048 microprocessors.

  • Linux in a Nutshell, 5th Edition By Stephen Figgins, Robert Love, Arnold Robbins, Ellen Siever, Aa

    Linux in a Nutshell, 5th Edition By Stephen Figgins, Robert Love, Arnold Robbins, Ellen Siever, Aaron Weber ... ... ... ... ... ... ... ..... Publisher: O Reilly Pub Date: July 2005 ISBN: 0-596-00930-5 Pages: 944 Over the last few years, Linux has grown both as an operating system and a tool for personal and business use. Simultaneously becoming more user friendly and more powerful as a back-end system, Linux has achieved new plateaus: the newer filesystems have solidified, new commands and tools have appeared and become standard, and the desktop--including new desktop environments--have proved to be viable, stable, and readily accessible to even those who don t consider themselves computer gurus.

    This paper addresses a stochastic-#ow network in which each arc or node has several capacities and may fail. Given the demand d, we try to evaluate the system reliability that the maximum #ow of the network is not less than d. A simple algorithm is proposed "rstly to generate all lower boundary points for d, and then the system reliability can be calculated in terms of such points. One computer example is shown to illustrate the solution procedure.

    The programming port of all the FP PLC’s support OPEN MEWTOCOL-COM. This is very useful when you want to monitor PLC values/bits or to set PLC values or bits via your computer. You can use any language such as Basic, C, Pascal, Assembler or even if other suppliers of PLCs can send ASCII strings, they can talk to our PLCs to exchange data.

    this a pack include source code for quartus 2. It is an implementation of the LC2. The LC-2 computer is described in Introduction to Computing Systems from Bits & Gates to C & Beyond by Yale Patt and Sanjay Patel, McGraw Hill, 2001. The LC2 model can be run as a simulation or downloaded to the UP3 in a larger model, TOP_LC2 that adds video output. Push buttons reset and single step the processor and a video output display of registers is generated. This state machine VHDL-based model of the LC-2 includes all source files. Currently compiled for a Cyclone EP1C6Q240 FPGA.
