OPEN-JTAG ARM JTAG 測試原理 1 前言 本篇報告主要介紹ARM JTAG測試的基本原理。基本的內容包括了TAP (TEST ACCESS PORT) 和BOUNDARY-SCAN ARCHITECTURE的介紹，在此基礎上，結合ARM7TDMI詳細介紹了的JTAG測試原理。 2 IEEE StANDard 1149.1 - Test Access Port and Boundary-Scan Architecture 從IEEE的JTAG測試標準開始，JTAG是JOINT TEST ACTION GROUP的簡稱。IEEE 1149.1標準最初是由JTAG這個組織提出，最終由IEEE批准並且標準化，所以，IEEE 1149.1這個標準一般也俗稱JTAG測試標準。 接下來介紹TAP (TEST ACCESS PORT) 和BOUNDARY-SCAN ARCHITECTURE的基本架構。

The P89LPC938 is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of StANDard 80C51 devices. Many system-level functions have been incorporated into the P89LPC938 in order to reduce component count, board space, and system cost.

The sample software includes, common library, peripheral APIs, and test modules for the APIs. The common library include startup file, StANDard definition and header files, processor specific setup module, generic interrupt related APIs, timer routine, and scatter loading file. The peripheral directories include, GPIO, PWM, Real-time clock, timer, SPI, I2C, Watchdog timer, UART, external interrupt, etc.

迭代自适应Simpson，Lobatto积分 In almost every StANDard book on numerics quadrature algorithms like the adaptive Simpson or the adaptive Lobatto algorithm are presented in a recursive way. The benefit of the recursive programming is the compact and clear representation. However, recursive quadrature algorithms might be transformed into iterative quadrature algorithms without major modifications in the structure of the algorithm. We present iterative adaptive quadrature algorithm (adaptiveSimpson and adaptiveLobatto), which preserves the compactness and the clarity of the recursive algorithms (e.g. quad, quadv, and quadl). Our iterative algorithm provides a parallel calculation of the integration function, which leads to tremendous gain in run-time, in general. Our results suggest a general iterative and not a recursive implementation of adaptive quadrature formulas, once the programming language permits parallel access to the integration function. For details the attached PDF file Conrad_08.pdf.

sim 文件系统In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements. At that former time, people hoped to build a based system, which could access a centralized server network, would always have access to the latest traffic information and could provide web links. What this trend is a momentous request for mobile services based on high-speed packet data transfer. Hence, a new StANDard, GPRS, came into being in order to fill people’s bill.

外国人开发的电磁时域有限差分方法工具包 Electromagnetic Finite-Difference Time-Domain (EmFDTD) is a basic two-dimensional FDTD code developed at the School of Electrical Engineering, Sharif University of Technology. This code has been written based on the StANDard Yee s FDTD algorithm. Applications include propagation, scattering, and diffraction of electromagnetic waves in homogeneous and non-homogeneous isotropic media for in-plane propagating waves. Negative permittivites or permeabilities as well as dispersion is not included. Zero, Periodic, and Perfectly Matched Layer boundary conditions may be selectively applied to the solution domain. The program is best suited for study of propagation and diffraction of electromagnetic waves in Photonic Crystal structures. EmFDTD is written in MATLAB language and has been tested under MATLAB 5.0 and higher versions.

The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control and data transfer communication between ICs. Some of the features of the I2C bus are: • Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A 12V supply line (500mA max.) for powering the peripherals often may be present. • Each device connected to the bus is software addressable by a unique address and simple master/ slave relationships exist at all times masters can operate as master-transmitters or as master-receivers. • The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data corruption if two or more masters simultaneously initiate data transfer systems. • Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the StANDard mode or up to 400 KBit/s in the fast mode.

是否懂得C语言并不是学习C++的前提。不仅仅是因为C++本身兼容C语言，更重要的是C++所倡导的程序设计观念是和C语言完全不同的。C语言在某种意义上是对CPU模型的抽象。尽管C++完全保留了C语言的机器模型，但是C++更加注重对现实世界进行抽象。为此，C++创始人Bjarne Stroustrup专门写过一篇著名的文章：《Learning StANDard C++ as a New Language》（把标准C++作为一种全新的语言来学习）
