摘要： Adjusting the confidence level of prefetch circuitry in generating outstanding prefetch address of a detected strided stream. In one example, the number of outstanding prefetches allowed is adjusted based on a determination of whether a prefetch to a prefetch address is used in a data processing system. With some systems, the higher the confidence level, the more outstanding prefetches are allowed.

摘要： Generating a hashed value of the program counter in a data processing system. The hashed value can be used for prefetching in the data processing system. In some examples, the hashed value is used to identify whether a load instruction associated with the hashed value has an address that is part of a strided stream in an address stream. In some examples, the hashed value is a subset of bits of the bits of the program counter. In other examples, the hashed value may be derived in other ways from the program counter.

摘要： Prefetching across a page boundary in a data processing system. The system determines whether a prefetch will cross a page boundary of memory, and if so, it determines whether a translation source has an entry corresponding to the virtual address of the prefetch. If the translation source has an entry corresponding the virtual address, a physical address of the virtual address is used to prefetch the information.

摘要： A program stream is executed at a first processing engine, the program stream including multiple iterations of a first load instruction. An instruction loop is executed at a second processing engine separate from the first processing engine substantially in parallel with an execution of the program stream at the first processing engine for prefetching data from memory to a buffer for one or more iterations of the first load instruction of the program stream. The instruction loop represents a subset of a sequence of instructions between iterations of the first load instruction that affect an address value associated with the first load instruction. A confidence value associated with the instruction loop is modified based on a prefetch performance of one or more iterations of the first load instruction and it is determined whether to terminate execution of the instruction loop based on the confidence value.

摘要： A first prefetch engine from a first plurality of prefetch engines is allocated to a first load instruction in response to a buffer miss of an iteration of the first load instruction in a program stream. The first plurality of prefetch engines include prefetch engines for prefetching data from memory to a buffer based on a predicted stride. A second prefetch engine from a second plurality of prefetch engines is allocated to the first load instruction in response to the buffer miss. The second plurality of prefetch engines include prefetch engines for prefetching data from memory to the buffer based on an instruction loop representative of a sequence of instructions that affect an address value associated with an allocated load instruction. One of the first or second prefetch engines is deallocated if the other prefetch engine achieves a prefetch performance greater than a first threshold value.
摘要翻译：来自第一多个预取引擎的第一预取引擎被分配给第一加载指令，以响应程序流中的第一加载指令的迭代的缓冲器未命中。第一组多个预取引擎包括预取引擎，用于基于预测步幅将数据从存储器预取到缓冲器。来自第二多个预取引擎的第二预取引擎被响应于缓冲器未命中而被分配给第一加载指令。第二组多个预取引擎包括预取引擎，用于将数据从存储器预取到缓冲器，这是基于代表影响与分配的加载指令相关联的地址值的指令序列的指令循环。如果其他预取引擎实现大于第一阈值的预取性能，则第一或第二预取引擎之一被释放。

摘要： In one embodiment, in a power converter system having first and second switches connected in a half-bridge arrangement at a common node from which current flows through an inductor to a regulated output terminal, wherein the regulated output terminal is connectable to a load, wherein the first and second switches are turned on and off in cycles, a method is provided for synchronous rectification. The method includes: initiating a cycle in which the first switch is turned on; developing a timer based on the on-time of the first switch during the cycle; turning off the first switch and turning on the second switch during the cycle; and outputting a control signal to turn off the second switch when either the timer expires or a new cycle is initiated to turn on the first switch, thereby providing synchronous rectification in the power converter system.

摘要： Gas lift valve designs and gas lift systems are described that feature a positive closure mechanism that is highly resistant to significant wear or damage that would result in fluid leakage. A pivotable flapper member is incorporated into a gas lift valve and used as a flow control mechanism. The flapper member provides a positive barrier to fluid flow from the production tubing to the annulus, even after substantial wear or damage.

摘要： A software development tool utilizes an intermediate object modeling language. The structure of the desired program is first described graphically by generating rule diagrams, state diagrams, and object diagrams such as user interface diagrams, event diagrams and other object diagrams. The development tool employs the diagrams to generate a working model of the program expressed in the object modeling language. The working model of the program can be executed without lengthy compiling, and hence program behavior can be quickly observed and tested. Further, the behavior of the working model can be quickly and easily changed by modifying the diagrams until the desired result is achieved. Source code is then generated from the object modeling language and compiled to create the final program.
