摘要： A method of detecting lost data within a data stream by inserting sequence numbers within the stream. Network data blocks to be transmitted are assembled from data chunks, where each data chunk contains a sequence number. Where the data is originating from multiple sources, the sequence numbers are labeled with an unique source ID, and are inserted into the composite data stream after one or more data chunks are generated.
摘要翻译：一种通过在流内插入序列号来检测数据流内的丢失数据的方法。要发送的网络数据块从数据块组装，其中每个数据块包含序列号。在数据来自多个源的地方，序列号用唯一的源ID标记，并且在生成一个或多个数据块之后被插入到复合数据流中。

摘要： Topology discovery of a target system having a plurality of components coupled with a scan topology may be performed by driving a low logic value on the data input signal and a data output signal of the scan topology. An input data value and an output data value for each of the plurality of components is sampled and recorded. A low logic value is then scanned through the scan path and recorded at each component. The scan topology may be determined based on the recorded data values and the recorded scan values.
摘要翻译：可以通过驱动数据输入信号上的低逻辑值和扫描拓扑的数据输出信号来执行具有与扫描拓扑结合的多个分量的目标系统的拓扑发现。对多个分量中的每一个的输入数据值和输出数据值进行采样和记录。然后通过扫描路径扫描低逻辑值，并记录在每个组件上。可以基于记录的数据值和记录的扫描值来确定扫描拓扑。

摘要： A method comprises a system comprising a host device coupled to a first remote device actively operating according to a state diagram that the host device and all remote devices follow during operation of the system. The method further comprises powering up a second remote device while the host device and first remote device are actively operating according to the state diagram. The second remote device waits for a synchronization point sequence. Upon detecting the synchronization point sequence, the second remote device implements a predetermined feature set and synchronizes itself to the state diagram at a common point as the host device and first remote device.

摘要： A system comprises a plurality of components, scan chain selection logic coupled to the components, and override selection logic coupled to the scan chain selection logic. The scan chain selection logic selects various of the components to be members of a scan chain under the direction of a host computer. The override selection logic detects a change in the scan chain and, as a result, blocks the entire scan chain from progressing.

The method further comprises powering up a second remote device while the host device and first remote device are actively operating according to the state diagram. The second remote device determines whether to initialize to a standard protocol or to an advanced protocol. Upon determining to initialize to the advanced protocol, the second remote device then waits for a synchronization point sequence.

摘要： The present disclosure describes systems and methods for controlling access to secure debugging and profiling features of a computer system. Some illustrative embodiments include a system that includes a processor, and a memory coupled to the processor (the memory used to store information and an attribute associated with the stored information). At least one bit of the attribute determines a security level, selected from a plurality of security levels, of the stored information associated with the attribute. Asserting at least one other bit of the attribute enables exportation of the stored information from the computer system if the security level of the stored information is higher than at least one other security level of the plurality of security levels.
