Memory Card is a memory card that is specifically designed to meet the security, capacity, performance, and environment requirements inherent in newly emerging audio and video consumer electronic devices. The SD Memory Card will include a content protection mechanism that complies with the security of the SDMI standard and will be faster and capable of higher Memory capacity. The SD Memory Card security system uses mutual authentication and a "new cipher algorithm" to protect against illegal usage of the card content. A Non-secure access to the user's own content is also available. SD memory cards may also support a second security system based on commonly used standards, such as ISO-7816, which can be used to interface the SD memory card into public networks and other systems supporting mobile e-commerce and digital signature applications

Petrify is a tool for the synthesis of bounded Petri nets and logic synthesis of asynchronous controllers. Petrify initially performs a token flow analysis of the Petri net and produces a finite transition system (TS). In the initial TS, all transitions with the same label are considered as one event. The TS is then transformed and transitions relabeled to fulfil the conditions required to obtain a Petri net with bisimilar or trace-equivalent behavior. Some properties for the synthesized Petri net can be imposed (e.g. free-choice, uniquechoice, pure, state-machine decomposable, etc.). Additionally, petrify can interpret the Petri net as a Signal Transition Graph (STG), in which events represent rising/falling transitions of digital signals. From an STG, petrify can synthesize a speed-independent circuit by solving the problems of state encoding, logic synthesis, logic decomposition and technology mapping onto a gate library. Petrify can also synthesize circuit under timing assumptions specified by the designer or automatically generated by the tool. Petrify reads the input description from stdin and writes the resulting STG to stdout unless otherwise specified

2018年7月4日发行的opencv3.4.2官方库是64位平台的，库文件是一个合并的opencv_world模块。这是经过VS2015从源码编译产生win32(x86)平台的动态库文件，含有分立的多个模块动态库，同时也含有一个合并的win32(x86)平台的opencv_world模块的动态库，方便使用。经简单测试可用。
