HDMI-Definition Multimedia Interface Specification Version 2.0This document constitutes the Version 2.0 specification for the High-Definition Multimedia Interface (HDMI Specification Version 2.0). This Specification incorporates HDMI Specification Version 1.4b by reference and defines additional and improved functionality. Mechanical, behavioral, and protocol requirements necessary for compliance are described for Sources, Sinks, Repeaters, and Cables.

HDMI (High Definition Media Interface， 高 清 多 媒 体接口 ) ，由于可以同时传输视频和音频数据，且连 接简单，兼容性好等特点，被广泛的应用在消费电 子产品上，例如电视，机顶盒，投影仪等。HDMI 系 统 可 以 划 分 4 个 种 类，Source，Sink，Cable ， 和 Repeater，为了保证这些设备良好的兼容性，规范对 电气信号做出了信号完整性的要求。

时序路径时序路径由设计中instance之间的连接决定。在数字设计中，时序路径由一对时序元作sequential elements）形成，这对时序元件由一个或二个不同的时钟控制。普通时序路径在任何设计中最普通的时序路径有以下4种：1输入端口到内部时序单元路径2从时序单元到时序单元之间的内部路径3从内部时序单元到输出端口之间的路径4输入端口到输出端口之间的路径输入端口到内部时序单元之间路径在从输入端口到内部时序单元之间的路径上传输的数据：通过管脚时钟送出器件经过一个称为输入延时的延时到达器件端口（SDC定义）在到达由目标时钟destination clock）锁定的时序单元之前须通过器件内部逻从时序单元到时序单元的内部路径在从时序单元到时序单元的内部路径上传输的数据：由时序单元发送到器件内部，而此时序单元由源时钟（source clock）驱动，在到达由日标时钟驱动的时宁单元之前，须经过一些内部逻辑内部时序单元到外部端口路径在从内部时序单元到外部端口路径上的数据：，由时序单元发送到器件内部，而此时序单元由源时钟（source clock）驱动，在到达外部端口之前，须经过一些内部逻辑，在经过一段称为输出廷时的额外延时之后被端口时钟捕获（SDC Definition）

INTRODUCTION In the past, adding speech recording and playback capability to a product meant using a digital signal processor or a specialized audio chip. Now, using a simplified Adaptive Differential Pulse Code Modulation(ADPCM) algorithm, these audio capabilities can be added to any PICmicro device. This application note will cover the ADPCM compression and decompression algorithms, performance comparison of all PICmicro devices, and an application using a PIC16C72 micro-controller.Definition OF TERMS step size -value of the step used for quantization of ana-log signals and inverse quantization of a number of steps.quantization -the digital form of an analog input signal is represented by a finite number of steps.adaptive quantization -the step size of a quantizer is dramatically changed with time in order to adapt to a changing input signal.inverse quantizer -a finite number of steps is converted into a digital representation of an analog signal.

Introduction The Sil9135/Sil9135A HDMI Receiver with Enhanced Audio and Deep Color Outputs is a second-generation dual-input High Definition Multimedia Interface(HDMI)receiver. It is software-compatible with the Sil9133receiver, but adds audio support for DTS-HD and Dolby TrueHD. Digital televisions that can display 10-or 12-bit color depth can now provide the highest quality protected digital audio and video over a single cable. The Sil9135and Sil9135A devices, which are functionally identical, can receive Deep Color video up to 12-bit,1080p @60Hz. Backward compatibility with the DVI 1.0specification allows HDMI systems to connect to existing DVI 1.0 hosts, such as HD set-top boxes and PCs. Silicon Image HDMI receivers use the latest generation Transition Minimized Differential Signaling(TMDS) core technology that runs at 25-225 MHz.The chip comes pre-programmed with High-bandwidth?
