The disclosed apparatus and method further uses estimation curves to estimate the desired position of a controlled gate valve which is located between the reaction chamber and turbo pump. The disclosed apparatus and method further introduces process gases at higher rate than set point levels to reduce the transition time or stabilization time required when raising the pressure in the reaction chamber.

摘要： In one embodiment, a processor comprises a first register file configured to store speculative register state, a second register file configured to store committed register state, a check circuit and a control unit. The first register file is protected by a first error protection scheme and the second register file is protected by a second error protection scheme.

The check circuit is configured to detect an error in the value responsive to the value and the check bits. Coupled to the check circuit, the control unit is configured to cause reexecution of the first instruction responsive to the error detected by the check circuit.

摘要： A processor including instruction support for large-operand instructions that use multiple register windows may issue, for execution, programmer-selectable instructions from a defined instruction set architecture (ISA). The processor may also include an instruction execution unit that, during operation, receives instructions for execution from the instruction fetch unit and executes a large-operand instruction defined within the ISA, where execution of the large-operand instruction is dependent upon a plurality of registers arranged within a plurality of register windows. The processor may further include control circuitry (which may be included within the fetch unit, the execution unit, or elsewhere within the processor) that determines whether one or more of the register windows depended upon by the large-operand instruction are not present. In response to determining that one or more of these register windows are not present, the control circuitry causes them to be restored.

摘要： Systems and methods for efficient execution of operations in a multi-threaded processor. Each thread may include a blocking instruction. A blocking instruction blocks other threads from utilizing hardware resources for an appreciable amount of time. One example of a blocking type instruction is a Montgomery multiplication cryptographic instruction. Each thread can operate in a thread-based mode that allows the insertion of stall cycles during the execution of blocking instructions, during which other threads may utilize the previously blocked hardware resources. At times when multiple threads are scheduled to execute blocking instructions, the thread-based mode may be changed to increase throughput for these multiple threads. For example, the mode may be changed to disallow the insertion of stall cycles. Therefore, the time for sequential operation of the blocking instructions corresponding to the multiple threads may be reduced.
摘要翻译：在多线程处理器中有效执行操作的系统和方法。每个线程可以包括阻塞指令。阻塞指令阻止其他线程在相当长的时间内利用硬件资源。阻塞型指令的一个例子是蒙哥马利乘法加密指令。每个线程都可以以线程为基础的模式运行，允许在执行阻塞指令期间插入停滞周期，在此期间其他线程可能利用先前阻止的硬件资源。在多个线程被调度执行阻塞指令的时候，可以改变基于线程的模式，以增加这些多线程的吞吐量。例如，可以改变该模式以不允许插入失速循环。因此，可以减少对应于多个线程的阻塞指令的顺序操作的时间。

摘要： Some embodiments of the present invention provide a processor, which includes a set of general-purpose registers and at least one execution unit. Each general-purpose register in the set of general-purpose registers is at least 64 bits wide, and the execution unit supports one or more Data Encryption Standard (DES) instructions. Specifically, the execution unit may support a permutation-rotation instruction for performing DES permutation operations and DES rotation operations. The execution unit may also support a round instruction to perform a DES round operation. Since the DES instructions use general-purpose registers instead of special-purpose registers to perform DES-specific operations, the processor's circuit complexity and area are reduced. Furthermore, in some embodiments, since the DES instructions require at most two operands, the number of bits required to specify the location of the operands are reduced, thereby enabling a larger number of instructions to be supported by the processor.
摘要翻译：本发明的一些实施例提供一种处理器，其包括一组通用寄存器和至少一个执行单元。通用寄存器组中的每个通用寄存器至少为64位宽，执行单元支持一个或多个数据加密标准（DES）指令。具体地，执行单元可以支持用于执行DES置换操作和DES旋转操作的置换旋转指令。执行单元还可以支持执行DES循环操作的循环指令。由于DES指令使用通用寄存器而不是专用寄存器来执行DES特定操作，所以处理器的电路复杂度和面积减少。此外，在一些实施例中，由于DES指令需要至多两个操作数，所以指定操作数的位置所需的位数减少，从而使更多数量的指令由处理器支持。
