Abstract: The invention features a method of reducing perceived network latency in processing a query from a handheld client device processed by a remote system. The client device receives incremental input including a sequence of incremental user actions for identifying content items on the remote system. The client device transmits a first subsequence of the input to the remote system for incrementally identifying descriptive terms associated with desired content items. The remote system selects a first set of content items based on the first subsequence and transmits them in a reply to the client device. The client device selects a second set of content items from the first set based on a second subsequence of the input. The second subsequence includes incremental input received by the client device while it was waiting for the first reply. The client device orders and presents the second set of content items to the user.

Abstract: A system uses a proxy server to authenticate a client with an authentication protocol that does not support caching. Rather than cache the client's authentication credentials, or access a client account manager for each network request generated by the client, the proxy server issues a cookie to an authenticated client and authenticate the client for subsequent request on the basis of the cookie.

Abstract: A superscalar processor includes a central scheduler for multiple execution units. The scheduler presumes operations issued to a particular execution unit all have the same latency, e.g., one clock cycle, even though some of the operations have longer latencies, e.g., two clock cycles. The execution unit that executes the operations having with longer than expected latencies, includes scheduling circuitry that holds up particular operation pipelines when operands required for the pipelines will not be valid when the scheduler presumes. Accordingly, the design of the scheduler can be simplified and can accommodate longer latency operations without being significantly redesigned for the longer latency operations.

Abstract translation: 超标量处理器包括用于多个执行单元的中央调度器。 即使一些操作具有较长的延迟，例如两个时钟周期，调度器假定发布到特定执行单元的操作都具有相同的等待时间，例如一个时钟周期。 执行具有长于预期延迟的操作的执行单元包括调度电路，当调度器假设时，当管道所需的操作数不成立时，该电路保持特定的操作流水线。 因此，可以简化调度器的设计，并且可以适应更长的延迟操作，而不会对较长的延迟操作进行显着的重新设计。

Abstract: A novel software framework monitors server statistics for a plurality of software modules and makes its collected statistics available to those modules. Unlike prior implementations, the framework provides shared server-monitoring code through which the plurality of software modules can monitor various types of servers, such as authentication servers, ICAP servers, origin servers, hierarchical proxy servers and so forth. Because the same server-monitoring code is accessed by each of the software modules, the overall amount of code that is written, compiled and executed may be reduced. Moreover, the shared server-monitoring code is not protocol-dependant and therefore may be coded outside of the kernel-level protocol engines. Preferably, the shared server-monitoring code is implemented as a user-level thread or process.

Abstract translation: 一个新颖的软件框架监视多个软件模块的服务器统计信息，并使其收集的统计信息可用于这些模块。 与先前的实现不同，框架提供共享的服务器监视代码，多个软件模块可以通过该代码来监视各种类型的服务器，例如认证服务器，ICAP服务器，原始服务器，分层代理服务器等。 由于每个软件模块访问相同的服务器监视代码，因此可以减少编写，编译和执行的代码的总量。 此外，共享服务器监视代码不是依赖于协议的，因此可以在内核级协议引擎之外进行编码。 优选地，共享服务器监视代码被实现为用户级线程或进程。

Abstract: A multimedia execution unit configured to perform vectored floating point and integer instructions. The execution unit may include an add/subtract pipeline having far and close data paths. The far path is configured to handle effective addition operations and effective subtraction operations for operands having an absolute exponent difference greater than one. The close path is configured to handle effective subtraction operations for operands having an absolute exponent difference less than or equal to one. The close path is configured to generate two output values, wherein one output value is the first input operand plus an inverted version of the second input operand, while the second output value is equal to the first output value plus one. Selection of the first or second output value in the close path effectuates the round-to-nearest operation for the output of the adder. The execution unit may be configured to perform vectored addition and subtraction, integer/floating point conversion, reverse subtraction, accumulate, extreme value (minimum/maximum), and comparison instructions.
