[Windows Develop] TS_sychrous_check

Description: 该模块主要用于MEPGII TS流同步检测。当连续检测到3个TS包同步时，输出一个同步有效信号，在该同步信号的驱动下，TS包写入FIFO中。该模块对检测TS包的有无及是否同步特别有效，希望对做数字电视的朋友有所帮助。-The module is mainly used for synchronous detection MEPGII TS stream. When detected in three consecutive TS packets simultaneously, the output of a sync signal, in which the sync signal driven, TS packet writing in FIFO. The module for detection of whether the TS packet and whether synchronization particularly effective, and they hope to make digital television a friend help.

Description: 在数字系统中，一般存在多个芯片，利用不同的特点用于实现不同的功能，一般都包含CPU,FPGA,AD,DA,memory，ASSP（专用标准模块）,ASIC等。CPU用于进行智能控制，FPGA进行硬件算法处理和多设备接口，AD进行模数转换，DA进行数模转换，memory存储临时数据。因此，FPGA如何与其他芯片进行通讯是重要的设计内容。数据输入，数据输出，双向通讯，指令传递，地址管理，不同时钟的异步通讯问题等等都需要处理。最基本的MEMORY如SRAM(128KX8bbit静态存储器628128)涉及到其中的输入，输出，双向通讯，地址管理问题，具有很强的代表性。在同步数字系统中更大量用到FIFO,SDRAM等等。其中FIFO使用方便简单，用处很广。在QUARTUSII软件库中，就有各种FPGA片内MEMORY供使用。但是FPGA的片内MEMORY容量太有限，因此外部MEMORY也是经常需要的。因此，本程序让大家学习控制芯片内外的MEMORY,为与其他智能设备的通讯学习打下基础。-In the digital system, generally there are several chips, the use of different features used to implement different functions, generally includes CPU, FPGA, AD, DA, memory, ASSP (application specific standard module), ASIC and so on.
