经过定点优化的G723、G729的codec In case you do not want to install IPP, then you"ll get twice better performance out of ITU-T code if you build it with GCC 4.5 or Intel CC with LTO/IPO enabled. Still, even with ICC, it is 10x slower than IPP - 30ms vs 3ms of processor time to encode one second of G.729 audio on modern hardware. G.723 is around 100ms. GCC with LTO is 2x slower than ICC. For ITU-T code, a Core2 class processor is recommended.

本系统以AT89C51为控制核心，由矩阵键盘输入，LED倒计时、交通灯显示等模块组成，模拟了一个交通灯控制系统。系统除基本交通灯功能外，还具有通行时间手动设置、可倒计时显示、急车强行通过、状态切换等相关功能。包括报告提供。-AT89C51 for the control of the system core, from the matrix keyboard input, LED countdown, traffic lights displays modules, to simulate a traffic light control system. In addition to basic traffic light system functions, but also has the passage of time to manually set to countdown show, worry about car forced through, the state switching and other related functions.
