摘要： An apparatus and method is described herein for providing a test, validation, and debug architecture. At a target or base level, hardware (Design for Test or DFx) are designed into and integrated with silicon parts. A controller may provide abstracted access to such hooks, such as through an abstraction layer that abstracts low level details of the hardware DFx. In addition, the abstraction layer through an interface, such as APIs, provides services, routines, and data structures to higher-level software/presentation layers, which are able to collect test data for validation and debug of a unit/platform under test. Moreover, the architecture potentially provides tiered (multiple levels of) secure access to the test architecture. Additionally, physical access to the test architecture for a platform may be simplified through use of a unified, bi-directional test access port, while also potentially allowing remote access to perform remote test and de-bug of a part/platform under test. In essence, a complete test architecture stack is described herein for test, validation, and debug of electronic parts, devices, and platforms.

摘要翻译： 这里描述了一种用于提供测试，验证和调试架构的装置和方法。 在目标或基础级别，硬件（测试设计或DFx）被设计并集成在硅部件中。 控制器可以提供对这种钩子的抽象访问，例如通过抽象层来抽象硬件DFx的低级细节。 此外，通过接口（如API）的抽象层向更高级的软件/表示层提供服务，例程和数据结构，这些层能够收集测试数据，以便对被测单元/平台进行验证和调试。 此外，该架构可能提供对测试架构的分层（多级）安全访问。 此外，可以通过使用统一的双向测试访问端口来简化对平台的测试架构的物理访问，同时还可能允许远程访问执行被测部件/平台的远程测试和脱离。 本质上描述了一个完整的测试架构栈，用于电子部件，设备和平台的测试，验证和调试。

摘要： In some embodiments, a serial bus interface circuit includes at least two serial ports, a memory to store a relationship between serial bus addresses and the at least two serial ports, and a controller to control access to the at least two serial ports. The controller may be configured to receive an access request for a serial bus address, determine a first port of the at least two serial ports corresponding to the serial bus address using the relationships stored in the memory, and disable a second port of the at least two serial ports. Other embodiments are disclosed and claimed.

摘要： A drone positioning system includes a processor subsystem and memory comprising instructions, which when executed by the processor subsystem, cause the processor subsystem to perform the operations comprising: transmitting, from an operation drone, a request message to a plurality of companion drones; receiving a response message from each of the plurality of companion drones, each response message including: a first timestamp indicating when the response message was sent from the corresponding companion drone and a first geoposition of the corresponding companion drone; calculating a first distance to each of the plurality of companion drones using the first timestamps of respective response messages from each of the plurality of companion drones; calculating an estimated geoposition of the operation drone from the respective first distances and the respective first geopositions of the companion drones; and assisting navigation of the operation drone using the estimated geoposition.

摘要： Screen recording may be implemented with better security, performance, power savings and cost without the need of additional software to support the screen recording feature, in some embodiments, by using a keyboard, video, mouse functionality already provided in a computer system chipset on a motherboard. Frames of video may be stored on that system or, in some cases, may be selectively provided to a local area network.
