摘要： A processor reduces wasted cycle time resulting from stalling and idling, and increases the proportion of execution time, by supporting and implementing both vertical multithreading and horizontal multithreading. Vertical multithreading permits overlapping or “hiding” of cache miss wait times. In vertical multithreading, multiple hardware threads share the same processor pipeline. A hardware thread is typically a process, a lightweight process, a native thread, or the like in an operating system that supports multithreading. Horizontal multithreading increases parallelism within the processor circuit structure, for example within a single integrated circuit die that makes up a single-chip processor. To further increase system parallelism in some processor embodiments, multiple processor cores are formed in a single die. Advances in on-chip multiprocessor horizontal threading are gained as processor core sizes are reduced through technological advancements.
摘要翻译：处理器通过支持和实现垂直多线程和水平多线程来减少由于停滞和空闲而导致的浪费周期时间，并增加执行时间的比例。垂直多线程允许重叠或“隐藏”高速缓存未命中等待时间。在垂直多线程中，多个硬件线程共享相同的处理器管道。在支持多线程的操作系统中，硬件线程通常是进程，轻量级进程，本机线程等。水平多线程增加了处理器电路结构内的并行性，例如在构成单片处理器的单个集成电路管芯内。为了在一些处理器实施例中进一步增加系统并行性，在单个管芯中形成多个处理器核。通过技术进步降低了处理器核心尺寸，从而获得片上多处理器水平线程的进步。

摘要： One embodiment of the present invention provides a system that efficiently emulates sub-instructions in a very long instruction word (VLIW) processor. The system operates by receiving an exception condition during execution of a VLIW instruction within a VLIW program. This exception condition indicates that at least one sub-instruction within the VLIW instruction requires emulation in software or software assistance. In processing this exception condition, the system emulates the sub-instructions that require emulation in software and stores the results. The system also selectively executes in hardware any remaining sub-instructions in the VLIW instruction that do not require emulation in software. The system finally combines the results from the sub-instructions emulated in software with the results from the remaining sub-instructions executed in hardware, and resumes execution of the VLIW program.

摘要： A computer system and associated method for executing a plurality of threads of execution with reduced memory space requirements. The computer system comprises a memory, an execution controller, and a data compressor. The execution controller controls execution of the threads such that the threads are executable and unexecutable at different times. The execution controller also stores uncompressed into available space in the run-time memory execution data of the threads when the execution data is generated. The data compressor compresses the uncompressed execution data of compressible ones of the threads that are unexecutable. As a result, space is made available in the run-time memory. The data compressor also decompresses in available space in the run-time memory the compressed execution data of decompressible ones of the threads so that the decompressible ones of the threads may be executed after becoming executable.

摘要： A system and method for establishing communications channels between and among peers in a peer-to-peer networking environment. Pipes may be used as communication channels for sending and receiving messages and other data between services or applications over input and output endpoints. Pipes may be asynchronous, unidirectional, stateless and unreliable. Bidirectional pipes may also be supported. Pipes may have ends that may be moved around and bound to different peers at different times. Point-to-point and propagate pipes may be supported. Pipes may connect peers that have a direct physical link and peers that do not have a direct link. Peers may communicate through pipes without knowing on which peer a pipe endpoint is bound. A message is sent to all peer endpoints currently connected (listening) to the pipe. The set of connected endpoints may be obtained from a pipe service using a pipe binding protocol.

摘要： A system and method for providing rendezvous nodes in a peer-to-peer networking environment is described. Rendezvous nodes preferably cache information about network resources that may be useful to peer nodes on a peer-to-peer network. In one embodiment, a network of rendezvous nodes may help peer nodes to discover network resources over long-range on the peer-to-peer network. Network resource may include, but may not be limited to peer nodes, peer groups, services, content, and communication channels. In one embodiment, rendezvous nodes may respond to discovery query messages from peer nodes. The discovery query messages may specify desired network resource information. In one embodiment, rendezvous nodes may provide route discovery for network resources. In one embodiment, a peer node may be pre-configured with a pre-defined set of rendezvous nodes to access on startup. These bootstrapping rendezvous may help the peer node discover network resources that it needs to start up.

摘要： A system and method for sending, resolving, and receiving queries for information on the status of network resources. A peer computing system may include one or more resolver nodes on a network for resolving queries for a resource to particular resource instances. The resolver nodes may receive query messages from peer nodes on the network. Each query message may request information about a resource implemented by one or more peer nodes on the network. The query messages may be formatted in accordance with a peer resolver protocol. The resolver node may determine a particular instance of the resource hosted on a particular peer node to receive the query. The resolver node may use a variety of criteria to determine a particular resource instance. The resolver node may forward the query message to the determined resource instance.

摘要： A processor includes a thread switching control logic that performs a fast thread-switching operation in response to an L1 cache miss stall. The fast thread-switching operation implements one or more of several thread-switching methods. A first thread-switching operation is “oblivious” thread-switching for every N cycle in which the individual flip-flops locally determine a thread-switch without notification of stalling. The oblivious technique avoids usage of an extra global interconnection between threads for thread selection. A second thread-switching operation is “semi-oblivious” thread-switching for use with an existing “pipeline stall” signal (if any). The pipeline stall signal operates in two capacities, first as a notification of a pipeline stall, and second as a thread select signal between threads so that, again, usage of an extra global interconnection between threads for thread selection is avoided. A third thread-switching operation is an “intelligent global scheduler” thread-switching in which a thread switch decision is based on a plurality of signals including: (1) an L1 data cache miss stall signal, (2) an instruction buffer empty signal, (3) an L2 cache miss signal, (4) a thread priority signal, (5) a thread timer signal, (6) an interrupt signal, or other sources of triggering. In some embodiments, the thread select signal is broadcast as fast as possible, similar to a clock tree distribution. In some systems, a processor derives a thread select signal that is applied to the flip-flops by overloading a scan enable (SE) signal of a scannable flip-flop.
摘要翻译：处理器包括线程切换控制逻辑，其响应于L1高速缓存未命中而执行快速线程切换操作。快速线程切换操作实现了几种线程切换方法中的一种或多种。第一个线程切换操作对于每个N个周期是“忽视的”线程切换，其中各个触发器本地确定线程切换而不通知失速。遗忘的技术避免了在线程选择的线程之间使用额外的全局互连。第二个线程切换操作是与现有的“流水线失速”信号（如果有的话）一起使用的“半隐匿”线程切换。流水线失速信号以两个容量运行，首先作为流水线停顿的通知，第二个作为线程之间的线程选择信号，这样就可以避免线程选择线程之间额外的全局互连使用。第三线程切换操作是“智能全局调度器”线程切换，其中线程切换决定基于多个信号，包括：（1）L1数据高速缓存未命中停止信号，（2）指令缓冲器空信号，（3）L2高速缓存未命中信号，（4）线程优先信号，（5）线程定时器信号，（6）中断信号或其他触发源。在一些实施例中，类似于时钟树分布，尽可能快地广播线程选择信号。在一些系统中，处理器通过过载可扫描触发器的扫描使能（SE）信号来导出施加到触发器的线程选择信号。

摘要： In summary, the present invention is a multithreaded computer system having a memory that stores a plurality of objects and a plurality of procedures. The system uses a first global hashing procedure to service requests for the hashcodes of objects that do not have hashcodes, a local object-specific hashing procedure to service requests for hashcodes that have a recently generated hashcode, and a second global hashing procedure to service requests for the hashcodes of objects that have their hashcodes stored with the object. The global object hashing procedure has instructions for creating for each object a local object-specific hashing procedure. The local object hashing procedure includes as private data a hashcode and instructions for retrieving the hashcode. The second global hashing procedure includes instructions for retrieving the hashcode from the object. A hashcode cleanup procedure, executed during the system's garbage collection process, releases the local object-specific hashing procedure of an object and stores the hashcode with the object.
摘要翻译：总之，本发明是具有存储多个对象和多个过程的存储器的多线程计算机系统。该系统使用第一全局散列过程来服务对不具有哈希码的对象的哈希码的请求，本地特定于对象的散列过程来服务具有最近生成的哈希码的哈希码的请求，以及用于服务请求的第二全局散列过程对于具有与对象存储的其哈希码的对象的哈希码。全局对象散列过程具有为每个对象创建本地特定于对象的散列过程的指令。本地对象散列过程包括作为专用数据的哈希码和用于检索哈希码的指令。第二个全局散列过程包括从对象中检索哈希码的指令。在系统的垃圾收集过程中执行的散列码清理过程释放对象的本地特定于对象的哈希过程，并将该哈希码存储在对象中。
