摘要： One embodiment of the present invention sets forth a technique for emitting coherent output from multiple threads for the printf( )function. Additionally, parallel (not divergent) execution of the threads for the printf( )function is maintained when possible to improve run-time performance. Processing of the printf( )function is separated into two tasks, gathering of the per thread data and formatting the gathered data according to the formatting codes for display. The threads emit a coherent stream of contiguous segments, where each segment includes the format string for the printf( )function and the gathered data for a thread. The coherent stream is written by the threads and read by a display processor. The display processor executes a single thread to format the gathered data according to the format string for display.
摘要翻译：本发明的一个实施例提出了一种用于从printf（）函数的多个线程发射相干输出的技术。另外，为了提高运行时性能，可以维护printf（）函数的线程的并行（不发散）执行。 printf（）函数的处理分为两个任务，每个线程数据的收集和格式化收集的数据根据显示的格式代码。线程发出连续段的相干流，其中每个段包括printf（）函数的格式字符串和线程收集的数据。相干流由线程写入并由显示处理器读取。显示处理器根据用于显示的格式字符串执行单个线程以格式化收集的数据。
