ecos RTOS 原理介紹和應用開發The design philosophy of eCos was to augment an open-source RTOS (which meant no
per-unit royalties) with source-level con?guration tools that would enable embedded developers
to scale their RTOS from hundreds of bytes to hundreds of kilobytes without needing to manu-
ally change a line of source code.
This SPI-mode SD Card controller is a free SOPC Builder component that can be used in any SOPC Builder system. The included example design runs on the Nios II Embedded Evaluation Kit, Cyclone III edition (NEEK).

This book introduces embedded systems to C and C++ programmers. Topics include testing memory devices, writing and erasing Flash memory, verifying nonvolatile memory contents, controlling on-chip peripherals, device driver design and implementation, optimizing embedded code for size and speed, and making the most of C++ without a performance penalty.
This is schematic and Gerber files of PCB that is used for GSM alarm system. This is industrial-grade system with many features like 1-wire (iButton) interface, additional interface for video camera (UART JPEG camera is used), SD card to store pictures from camera and send them by GSM to remote mobile phone.
Can be used as a reference design for anyone who wants to make own GSM alarm system system based on SIM300C module from Simcom.
Altera® provides various tools for development of hardware and software for embedded systems. This handbook complements the primary documentation for these tools by describing how to most effectively use the tools. It recommends design styles and practices for developing, debugging, and optimizing embedded systems using Altera-provided tools. The handbook introduces concepts to new users of Altera’s embedded solutions, and helps to increase the design efficiency of the experienced user.
High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support.
For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled
in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB
signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0
signaling running at hundreds of MHz, the existing design methodology must change.
