    • A processor receives a command via a sideband interface on the processor to read processor state information, e.g., CPUID information. The sideband interface provides the command information to a microcode engine in the processor that executes the command to retrieve the designated processor state information at an appropriate instruction boundary and retrieves the processor state information. That processor information is stored in local buffers in the sideband interface to avoid modifying processor state. After the microcode engine completes retrieval of the information and the sideband interface command is complete, execution returns to the normal flow in the processor. Thus, the processor state information may be obtained non-destructively during processor runtime.
    • 处理器经由处理器上的边带接口接收命令以读取处理器状态信息,例如CPUID信息。 边带接口向处理器中的微代码引擎提供命令信息,执行命令以在适当的指令边界检索指定的处理器状态信息并检索处理器状态信息。 该处理器信息存储在边带接口中的本地缓冲区中,以避免修改处理器状态。 在微代码引擎完成信息的检索并且边带接口命令完成之后,执行返回处理器中的正常流程。 因此,可以在处理器运行时期间非破坏性地获得处理器状态信息。

    • A processor supports a processing mode in which the address size is greater than 32 bits and the operand size may be 32 or 64 bits. The address size may be nominally indicated as 64 bits, although various embodiments of the processor may implement any address size which exceeds 32 bits, up to and including 64 bits, in the processing mode. The processing mode may be established by placing an enable indication in a control register into an enabled state and by setting a first operating mode indication and a second operating mode indication in a segment descriptor to predefined states. Other combinations of the first operating mode indication and the second operating mode indication may be used to provide compatibility modes for 32 bit and 16 bit processing compatible with the x86 processor architecture (with the enable indication remaining in the enabled state).
    • 处理器支持地址大小大于32位的处理模式,操作数大小可以是32位或64位。 地址大小可以名义上表示为64位,尽管在处理模式下,处理器的各种实施例可以实现超过32位,高达并包括64位的任何地址大小。 可以通过将控制寄存器中的使能指示置于使能状态并且通过将段描述符中的第一操作模式指示和第二操作模式指示设置为预定状态来建立处理模式。 可以使用第一操作模式指示和第二操作模式指示的其他组合来提供与x86处理器架构兼容的32位和16位处理的兼容性模式(使能指示保持在使能状态)。

    • A processor is configured to operate in a modes which utilize segmentation and which do not utilize segmentation. The processor includes circuitry which is configured to detect and respond to mode and state changes. The circuitry is configured to determine whether a segmentation state of the processor changes in response to execution of a control transfer operation. If the segmentation state does not change as a result of the transfer instruction, execution of instructions may continue sequentially and a corresponding first check performed. However, if the segmentation state does change as a result of the transfer instruction, a flush of the pipeline is initiated prior to performing a corresponding second check. When a first mode of operation is detected a limit check may be performed, while a canonical check may performed when a second mode of operation is detected. A special register is defined which is configured to indicate changes in segmentation state subsequent to a control transfer operations. A read of the special register may then be performed in order to determine whether a state change is indicated.
    • 处理器被配置为以利用分段并且不利用分段的模式操作。 处理器包括被配置为检测并响应模式和状态改变的电路。 电路被配置为确定处理器的分段状态是否响应于控制传送操作的执行而改变。 如果作为传送指令的结果,分段状态不改变,则指令的执行可以顺序地继续进行并进行相应的第一检查。 然而,如果作为转移指令的结果,分段状态确实改变,则在执行相应的第二次检查之前启动流水线的刷新。 当检测到第一操作模式时,可以执行极限检查,而当检测到第二操作模式时可以执行规范检查。 定义特殊寄存器,其被配置为指示在控制传送操作之后的分段状态的改变。 然后可以执行特殊寄存器的读取,以便确定是否指示状态改变。

    • An automotive fluid control system with pressure balanced solenoid valve [24] and fluid mixing housing [22] is disclosed. The solenoid valve [24] is preferably used in an EGR (exhaust gas circulation) fluid control system, although the valve may be used in other vehicle fluid control systems, such as an engine block cooling liquid control system. A poppet member [84] of an EGR valve is pressured balanced such that only a light spring [170] and armature [88] are needed to control the positioning of the poppet member [84]. Magnetic and inductance sensors [184, 282] are used to accurately determine the position of the poppet member. The fluid mixing housing [22] homogeneously mixes first and second fluids. A portion of a main first fluid flow is funneled off and mixed in the housing [22] with a second fluid prior to being returned to the main fluid flow. Ideally, the housing [22] has a circumferentially extending channel [95] for intercepting, funnelling and mixing the captured portion of the main first fluid flow with the second fluid flow. Also, a solenoid subassembly [82] is disclosed which can mate with a variety of different valve housings [22] and which is adapted to mount on various engine configurations.
    • 公开了一种具有压力平衡电磁阀[24]和流体混合壳体[22]的汽车流体控制系统。 电磁阀[24]优选用于EGR(排气循环)流体控制系统,尽管该阀可用于其他车辆流体控制​​系统,例如发动机缸体冷却液控制系统。 EGR阀的提升阀构件[84]被加压平衡,使得只需要一个弹簧[170]和电枢[88]来控制提升阀构件[84]的定位。 磁性和电感传感器[184,282]用于准确地确定提升阀构件的位置。 流体混合壳体[22]均匀混合第一和第二流体。 主要第一流体流的一部分在被返回到主流体流之前用第二流体漏出并在壳体[22]中混合。 理想地,壳体22具有周向延伸的通道,用于拦截,漏斗和混合主要第一流体流的捕获部分与第二流体流。 此外,公开了一种螺线管子组件[82],其可以与各种不同的阀壳体[22]配合,并且其适于安装在各种发动机构造上。
