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）

A few short years ago, the applications for video were somewhat confined—analog was used for broadcast and cable television, VCRs, set-top boxes, televisions and camcorders. Since then, there has been a tremendous and rapid conversion to digital video, mostly based on the MPEG-2 video compression standard. Today, in addition to the legacy DV, MPEG-1 and MPEG-2 audio and video com- pression standards, there are three new high- performance video compression standards. These new video codecs offer much higher video compression for a given level of video quality.

M3GExport enables developers to export complex 3D animated scenes from Maya® directly to Mobile 3D Graphics file format (M3G), the emerging 3D file format for mobile 3D games. Created by the developers of JBenchmark3D - the leading performance measurement tool for mobile 3D graphics, M3GExport lets use sophisticated features of M3G format like skeletal animation, morphing meshes, triangle stripping and other useful optimisations. M3GExport for Maya is available in two editions, Limited and Standard. The Standard version contains sophisticated optimisation options used mostly by commercial game developers.

APCS，ARM 过程调用标准(ARM Procedure Call Standard)，提供了紧凑的编写例程的一种机制，定义的例程可以与其他例程交织在一起。最显著的一点是对这些例程来自哪里没有明确的限制。它们可以编译自 C、 Pascal、也可以是用汇编语言写成的。

The DHRY program performs the dhrystone benchmarks on the 8051. Dhrystone is a general-performance benchmark test originally developed by Reinhold Weicker in 1984. This benchmark is used to measure and compare the performance of different computers or, in this case, the efficiency of the code generated for the same computer by different compilers. The test reports general performance in dhrystones per second. Like most benchmark programs, dhrystone consists of standard code and concentrates on string handling. It uses no floating-point operations. It is heavily influenced by hardware and software design, compiler and linker options, code optimizing, cache memory, wait states, and integer data types. The DHRY program is available in different targets: Simulator: Large Model: DHRY example in LARGE model for Simulation Philips 80C51MX: DHRY example in LARGE model for the Philips 80C51MC

I often need a simple function generator. Just to generate a certain frequency. After all the years I ve worked with electronics, I still haven t got me one. Even though I need it now and then, I just couldn t seem to justify the cost of one. So, standard solution - build one yourself. I designed a simple sinewave generator based on a Analog Devices AD9832 chip. It will generate a sinewave from 0.005 to 12 MHz in 0.005 Hz steps. That s pretty good, and definitely good enough for me ! But while waiting for the AD9832 chip to arrive, I came up with a very simple version of the DDS synth, using just the 2313 and a resistor network.
