摘要： In a computer system, an apparatus is configured to collect performance data of a computer system including a plurality of processors for concurrently executing instructions of a program. A plurality of performance counters are coupled to each processor. The performance counters store performance data generated by each processor while executing the instructions. An interrupt handler executes on each processors, the interrupt handler samples the performance data of the processor in response to interrupts. A first memory includes a hash table associated with each interrupt handler, the hash table stores the performance data sampled by the interrupt handler executing on the processor. A second memory includes an overflow buffer, the overflow buffer stores the performance data while portions of the hash tables are active or full. A third memory includes a user buffer, and means are provided for periodically flushing the performance data from the hash tables and the overflow to the user buffer.

摘要： An apparatus includes a computer executable for processing a file of a first file type, and a Hypertext Transfer Protocol (“HTTP”) client that receives files of the first type and a second type from a network. The HTTP client causes the computer executable to process files of the first type. The computer executable includes a first module that determines whether the file includes a first content type and performs a first function if the file includes the first content type. The computer executable also includes a second module that determines whether the file includes a second content type and performs a second function different from the first function if the file includes the second content type.

摘要： A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes. The instruction set is limited to register-to-register operations and register load/store operations. Byte manipulation instructions, included to permit use of previously-established data structures, include the facility for doing in-register byte extract, insert and masking, along with non-aligned load and store instructions. The provision of load/locked and store/conditional instructions permits the implementation of atomic byte writes. By providing a conditional move instruction, many short branches can be eliminated altogether. A conditional move instruction tests a register and moves a second register to a third if the condition is met; this function can be substituted for short branches and thus maintain the sequentiality of the instruction stream.

摘要： A computer system using virtual memory addressing and having a direct-mapped cache is operated in a manner to simulate the effect of a set associative cache by detecting cache misses and remapping pages in the main memory so that memory references which would have caused thrashing can instead coexist in the cache. Two memory addresses which are in different pages but which map to the same location in the cache may not reside in the direct-mapped cache at the same time, so alternate reference to these addresses by a task executing on the CPU would cause thrashing. However, if the location of one of these addresses in main memory is changed, the data items having these addresses can coexist in the cache, and performance will be markedly improved because thrashing will no longer result. For a CPU executing a virtual memory operating system, a page of data or instructions can be moved to a different physical page frame but remain the same virtual address. This is accomplished by simply updating the page-mapping tables to reflect the new physical location of the page, and copying the data from the old page frame to the new one. The thrashing condition is detected and corrected dynamically by latching cache miss addresses and periodically sampling the latch, then remapping pages containing the addresses found upon sampling. The direct-mapped cache must be large enough to hold two or more pages.
摘要翻译：使用虚拟存储器寻址并具有直接映射高速缓存的计算机系统以通过检测主存储器中的高速缓存未命中和重新映射页面来模拟集合关联高速缓存的效果的方式操作，使得可能导致thrashing的存储器引用可以改为在缓存中并存。位于不同页面但映射到高速缓存中相同位置的两个内存地址可能不会同时驻留在直接映射高速缓存中，因此在CPU上执行的任务对这些地址的备用引用将导致颠覆。然而，如果主存储器中的这些地址之一的位置改变，则具有这些地址的数据项可以在高速缓存中共存，并且性能将被显着改善，因为不再产生抖动。对于执行虚拟存储器操作系统的CPU，可以将一页数据或指令移动到不同的物理页框，但保持相同的虚拟地址。这是通过简单地更新页面映射表来反映页面的新的物理位置，并将数据从旧页面框架复制到新的页面框架来实现的。通过锁存缓存未命中地址并周期性地对锁存器进行采样来检测和纠正抖动条件，然后重新映射包含在采样时找到的地址的页面。直接映射缓存必须足够大以容纳两个或多个页面。

摘要： Information about the location of untranslated instructions in an original program is discovered during execution of a partial translation of the program, and that information is used later during re-translation of the original program. Preferably the information includes origin addresses of translated instructions and corresponding destination address of untranslated instructions of execution transfers that occur during the execution of the partial translation. Preferably this feedback of information from execution to re-translation is performed after each execution of the translated program so that virtually all of the instructions in the original program will eventually be located and translated. To provide an indication of the fraction of the code that has been translated, the program is scanned to find plausible code in the areas of memory that do not contain translated code. The plausible code is identified by selecting addresses according to three different scanning modes and attempting to decode variable-length instructions beginning at the selected addresses. The scanning modes include a first mode in which addresses are selected in numerical sequence by a scan pointer, a second mode in which addresses are selected in instruction-length sequence by an instruction decode pointer, and a third mode in which the selected addresses are destination addresses of previously-decoded execution transfer instructions.
摘要翻译：在程序的部分翻译执行期间发现关于原始程序中未翻译指令的位置的信息，并且该信息在以后在原始程序的重新翻译期间被使用。优选地，信息包括翻译的指令的起始地址和在执行部分转换期间发生的执行转移的非翻译指令的对应目的地地址。优选地，在每次执行翻译的程序之后执行从执行到重新翻译的信息的反馈，使得原始程序中的几乎所有指令最终将被定位和翻译。为了提供已经翻译的代码部分的指示，扫描程序以在不包含翻译代码的存储器区域中找到合理的代码。通过根据三种不同的扫描模式选择地址并尝试解码从所选择的地址开始的可变长度指令来识别合理的代码。扫描模式包括第一模式，其中通过扫描指针以数字顺序选择地址，其中通过指令解码指针在指令长度序列中选择地址的第二模式，以及其中所选择的地址是目的地的第三模式先前解码的执行传输指令的地址。

摘要： Methods and apparatus for document based ambiguous character resolution. An application searches a document for words that do not contain ambiguous characters and adds them to a dictionary, then searches the document for words that do contain ambiguous characters. For each ambiguous word, a set of candidate solutions is created by resolving the ambiguous characters in all possible ways. The dictionary is searched for words matching members of the candidate solution set. When a single member is matched, the ambiguous characters are resolved accordingly. When no member or more than one member is matched, a user is prompted to resolve the ambiguous characters. Alternatively, when more than one member is matched, the ambiguous characters are resolved to obtain the largest word, the smallest word, the most words, or the fewest words.
