    SAM9261 BasicMMU Example code with ADS1.2 (163 kB) The goal of this project is to show how to use a PC100 SDRAM and the MMU to perform a rating with a 100MHz Bus Clock. The rating is based on Dhrystone 2.1. It shows the rate when I+D Caches are disabled or enabled, with or without MMU and I Cache is disable or enabled, with or without MMU.

  • UCOS/II for ICCAVR - The version of UCOS/II is 2.04 - the original port was done by Ole Saether

    UCOS/II for ICCAVR - The version of UCOS/II is 2.04 - the original port was done by Ole Saether for the IAR compiler. Jens E. Holtegaard ported one version using ICCAVR. Joerg Meyer did another port (using Jens port as a start?). This is basically Joerg s port plus a little bit of changes and documentation by me. - YOU MUST DOWNLOAD THE MAIN PART OF THE UCOS/II FROM THE UCOS/II WEBSITE http://www.ucos-ii.com . The supplied project file assumes the portable source is in the ..\source directory. - Joerg has written couple document showing the stack frames etc. but it is in German :-) They are included in this directory. - The Timer2 overflow interrupt is used for Timer Tick. If you want to change that, modify os_cpu_c.c and os_cpu_a.s - I have tested this using ATMega103 with and without external RAM using AVR Studio simulator. See test1.c test program. Both Code Compressed (PRO) and STD versions have been tested.

    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.

    About: hamsterdb is a database engine written in ANSI C. It supports a B+Tree index structure, uses memory mapped I/O (if available), supports cursors, and can create in-memory databases. Release focus: Major feature enhancements Changes: This release comes with many changes and new features. It can manage multiple databases in one file. A new flag (HAM_LOCK_EXCLUSIVE) places an exclusive lock on the file. hamsterdb was ported to Windows CE, and the Solution file for Visual Studio 2005 now supports builds for x64. Several minor bugs were fixed, performance was improved, and small API changes occurred. Pre-built libraries for Windows (32-bit and 64-bit) are available for download. Author: cruppstahl

    VHDL實現SPI功能源代碼 -- The SPI bus is a 3 wire bus that in effect links a serial shift -- register between the "master" and the "slave". Typically both the -- master and slave have an 8 bit shift register so the combined -- register is 16 bits. When an SPI transfer takes place, the master and -- slave shift their shift registers 8 bits and thus exchange their 8 -- bit register values.

    This directory builds the Tape class driver for Microsoft® Windows® Server 2003. The class driver implements device-independent support, and exports support routines for device-specific tape miniclass drivers. It handles device-independent tape requests and calls the tape minidriver routines to process device-specific functions. Class driver splits transfer requests, when necessary, to fit the maximum transfer size for the underlying host bus adapter. It also provides device-independent, tape-specific error handling, and calls the tape miniclass driver s device-specific error handling routines.

    This is the library for all storage drivers. It simplifies writing a storage driver by implementing 90 percent of the code required to support Plug and Play, Power Management, et cetera. This library is used by disk.sys, cdrom.sys and the tape class drivers. No INF file is needed to install this library. The library is 64-bit compliant.
