摘要： When events are traced, the timing stream is used to associate events with instructions and indicate pipeline advances precluding the recording of stall cycles. Additional information is needed in the trace stream to identify an overlay whose execution of code is in a system where overlays or a memory management unit are used. In the case of PC trace, additional information is added when the memory system contents is changed. Information describing the configuration change is inserted into the export streams by placing this information in a message buffer. As long as a message word is available for output, it becomes the next export word as the output of message words is continuous.
摘要翻译：当跟踪事件时，定时流用于将事件与指令相关联，并指示流水线进展阻止了停顿周期的记录。跟踪流中需要附加信息，以识别其执行代码在使用叠加层或存储器管理单元的系统中的覆盖。在PC跟踪的情况下，当更改内存系统内容时会添加附加信息。通过将该信息放在消息缓冲区中，将描述配置更改的信息插入到导出流中。只要消息字可用于输出，它将成为下一个导出字，因为消息字的输出是连续的。

摘要： A method and system of identifying overlays used by a program. The overlays may be executable overlays (e.g., overlay programs and dynamically linked library programs), or the overlays may be data sets. Depending on the number of overlays and/or the type of information used to identify the overlays, an indication of the identity of the overlays may be written to a register (whose contents are inserted into the trace data stream), or the indication may comprise an entry in a log buffer and an index value written to the register (again whose contents are inserted into the trace data stream, and where the index value identifies the entry in the log buffer).

摘要： The present disclosure describes methods and systems for secure debugging and profiling of a computer system. Some illustrative embodiments may include a system including a processor with a first processing stage and a first attribute register associated with the first processing stage, and including a memory system coupled to the processor. An instruction and an attribute value are stored within the memory system, wherein the instruction is loaded into the first processing stage and the attribute value is loaded into the first attribute register. Export of debug and profiling data from the first processing stage is disabled if the attribute value in the first attribute register indicates that the instruction in the first processing stage is a secure instruction, and further indicates that secure emulation is disabled.

摘要： A method and apparatus for encoding video includes selecting a prediction motion vector for a current block of a current image frame from respective motion vectors of two or more neighbor blocks of the current block. Then the current block and a neighbor block corresponding to said prediction motion vector are checked to determine whether they are motion correlated. Checking motion correlation includes determining that the difference between the best correlation from the correlation of the current block with one or more neighbor blocks and the correlation of the neighbor block with a block in the previous image frame at a location defined by the prediction motion vector fulfils a predetermined criterion.

摘要： This invention is a JPEG2000 arithmetic encoder with improvements to conventional JPEG2000 encoder implementations. This invention decouples co-efficient bit modeling from arithmetic encoding, eliminates the RENORME while loop through least most bit detection, decouples encoding from BYTEOUT, exploits parallelism across conditional execution paths, uses look-up table storage and packing of context state data and eliminates memory dependencies through direct register forwarding.

摘要： A method and system of indexing into trace data based on entries in a log buffer. At least some of the illustrative embodiments are methods comprising executing a traced program on a target device. The traced program writes entries to a log buffer within the target device, and the traced program also contemporaneously writes an index value for each entry to a register. The index value written to the register becomes part of trace data regarding the traced program and correlates each entry to a respective portion of the trace data. Using the information one may either or both: display on a display device a portion of the trace data (the portion selected based on selecting an entry from the log buffer); or display on the display a portion of the log buffer (the portion selected based on selecting an entry from the trace data).
摘要翻译：根据日志缓冲区中的条目将索引数据进行索引的方法和系统。说明性实施例中的至少一些是包括在目标设备上执行跟踪的程序的方法。跟踪的程序将条目写入目标设备中的日志缓冲区，并且跟踪的程序同时将每个条目的索引值写入寄存器。写入寄存器的索引值成为跟踪程序的跟踪数据的一部分，并将每个条目与跟踪数据的相应部分相关联。使用该信息可以一个或两者：在显示设备上显示跟踪数据的一部分（基于从日志缓冲器中选择条目而选择的部分）; 或在显示器上显示日志缓冲区的一部分（基于从跟踪数据中选择条目而选择的部分）。
