    • An integrated circuit (IC) design verification system includes a memory for storing an IC design and a processor in communication with the memory. The IC design includes multiple IP cores and the design verification apparatus includes multiple verification modules. The processor configures a first set of connections between the IP cores and the verification modules based on a first connection database and verifies each IP core independently using the first set of connections. Thereafter, the processor configures a second set of connections between the IP cores and the verification modules based on a second connection database generated based on the first connection database, and verifies the multiple IP cores together using the second set of connections.
    • 集成电路(IC)设计验证系统包括用于存储IC设计的存储器和与存储器通信的处理器。 IC设计包括多个IP核,设计验证装置包括多个验证模块。 处理器基于第一连接数据库配置IP核和验证模块之间的第一组连接,并使用第一组连接独立地验证每个IP核。 此后,处理器基于基于第一连接数据库生成的第二连接数据库来配置IP核和验证模块之间的第二组连接,并且使用第二组连接来验证多个IP内核。

    • A method of authentication is provided that includes capturing biometric data for a desired biometric type from an individual, determining an algorithm for converting the biometric data into authentication words, converting the captured biometric data into authentication words in accordance with the determined algorithm, including the authentication words in a probe, and comparing the probe against identity records stored in a server system. Each of the identity records includes enrollment biometric words of an individual obtained during enrollment. Moreover, the method includes identifying at least one of the identity records as a potential matching identity record when at least one of the authentication words included in the probe matches at least one of the enrollment biometric words included in the at least one identity record, and generating a list of potential matching identity records.
    • 提供了一种认证方法,其包括从个体捕获期望的生物特征类型的生物特征数据,确定用于将生物统计数据转换成认证字的算法,根据所确定的算法将捕获的生物统计数据转换成认证字,包括认证 探针中的单词,以及将探针与存储在服务器系统中的身份记录进行比较。 每个身份记录包括在注册期间获得的个人的登记生物特征词。 而且,当包括在探测器中的认证字中的至少一个与至少一个身份记录中包括的登记生物识别词中的至少一个匹配时,该方法包括将身份记录中的至少一个标识为潜在的匹配身份记录,以及 生成潜在的匹配身份记录列表。

    • A method and controller for supporting out of order execution of instructions is described. A microprocessor is coupled to a coprocessor via a controller. Instructions are received by the microprocessor and the controller. Indices respectively associated with the instructions are generated by the microprocessor, and the instructions are popped from the first queue for execution by the coprocessor. The controller includes a first queue and a second queue. The instructions and the indices are queued in the first queue, and this first queuing includes steering the instructions and the indices associated therewith to respective first register locations while maintaining association between the instructions and the indices. The instructions may be popped off the first queue out of order with respect to an order in which the instructions are received into the first queue.
    • 描述了用于支持指令执行不正常的方法和控制器。 微处理器经由控制器耦合到协处理器。 微处理器和控制器接收到指令。 分别与指令相关联的指示由微处理器产生,并且指令从第一个队列弹出,以供协处理器执行。 控制器包括第一队列和第二队列。 指令和索引在第一队列中排队,并且该第一排队包括将指令和与其相关联的索引转向相应的第一注册位置,同时保持指令和索引之间的关联。 相对于其中指令被接收到第一队列中的顺序,指令可以从第一队列中弹出。
