摘要： Applications software can be rapidly tested and developed for a multi-processor chip even though the hardware of new processors of the multi-processor chip is not yet available. This can be accomplished by executing software simulations of the new processor designs and corresponding applications software either on a previously designed processor that is hardware on the multi-processor chip or on a workstation development platform. The execution of the previously designed processor is typically much faster than the execution on a simulator running on a personal workstation development platform, and therefore the execution time is quicker. Furthermore, the processor simulation and application software can be configured to take advantage of the platform most appropriate for execution and avoid simulation of portions of the new processors that are not necessary for testing the applications software.

摘要： A profiler or scanning probe microscope may be scanned across a sample surface with a distance between them controlled to allow the sensing tip to contact the surface intermittently in order to find and measure features of interest. The distance is controlled so that when the sensing tip is raised or lowered to touch the sample surface, there is no lateral relative motion between the tip and the sample. This prevents tip damage. Prior knowledge of the height distribution of the sample surface may be provided or measured and used for positioning the sensing tip initially or in controlling the separation to avoid lateral contact between the tip and the sample. The process may also be performed in two parts: a fast find mode to find the features and a subsequent measurement mode to measure the features. A quick step mode may also be performed by choosing steps of lateral relative motion to be smaller than 100 nanometers to reduce probability of tip damage. In this mode, after each vertical step to increase the separation between the tip and the sample, it is detected as to whether the tip and the sample are in contact. If they are still in contact after the vertical step, one or more vertical steps are taken to increase the separation, and no vertical step to reduce the separation is taken and no lateral relative motion is caused until it is determined that the tip and the sample are no longer in contact.

摘要： A dual stage scanning instrument includes a sensor for sensing a parameter of a sample and coarse and fine stages for causing relative motion between the sensor and the sample. The coarse stage has a resolution of about 1 micrometer and the fine stage has a resolution of 1 nanometer or better. The sensor is used to sense the parameter when both stages cause relative motion between the sensor assembly and the sample. The sensor may be used to sense height variations of the sample surface as well as thermal variations, electrostatic, magnetic, light reflectivity or light transmission parameters at the same time when height variation is sensed. By performing along scan at a coarser resolution and short scans a high resolution using the same probe tip or two probe tips at fixed relative positions, data obtained from the long and short scans can be correlated accurately.

摘要： A macropipelined microprocessor chip adheres to strict read and write ordering by sequentially buffering operands in queues during instruction decode, then removing the operands in order during instruction execution. Any instruction that requires additional access to memory inserts the requests into the queued sequence (in a specifier queue) such that read and write ordering is preserved. A specifier queue synchronization counter captures synchronization points to coordinate memory request operations among the autonomous instruction decode unit, instruction execution unit, and memory sub-system. The synchronization method does not restrict the benefit of overlapped execution in the pipelined. Another feature is treatment of a variable bit field operand type that does not restrict the location of operand data. Instruction execution flows in a pipelined processor having such an operand type are vastly different depending on whether operand data resides in registers or memory. Thus, an operand context queue (field queue) is used to simplify context-dependent execution flow and increase overlap. The field queue allows the instruction decode unit to issue instructions with variable bit field operands normally, sequentially identifying and fetching operands, and communicating the operand context that specifies register or memory residence across the pipeline boundaries to the autonomous execution unit. The mechanism creates opportunity for increasing the overlap of pipelined functions and greatly simplifies the splitting of execution flows.
摘要翻译：宏指令微处理器芯片通过在指令解码期间依次缓冲队列中的操作数，然后在指令执行期间依次移除操作数，从而遵循严格的读写顺序。任何需要对内存进行访问的指令将请求插入排队的序列（在指定符队列中），以便保留读写顺序。指定符队列同步计数器捕获同步点以协调自主指令解码单元，指令执行单元和存储器子系统之间的存储器请求操作。同步方法不限制流水线重叠执行的好处。另一个特征是处理不限制操作数数据位置的可变位字段操作数类型。具有这种操作数类型的流水线处理器中的指令执行流程根据操作数数据位于寄存器或存储器中而大不相同。因此，操作数上下文队列（字段队列）用于简化上下文相关的执行流程并增加重叠。字段队列允许指令解码单元通常发送具有可变位字段操作数的指令，顺序地识别和取出操作数，以及将指定流水线边界的寄存器或存储器驻留的操作数上下文传送到自主执行单元。该机制为增加流水线功能的重叠创造了机会，并大大简化了执行流程的拆分。

摘要： A first thermally conductive plate holds an article and heats the article with heating elements in the plate. Parallel rails support the first plate above a base. Cooling passageways for coolant flow are in a second thermally conductive plate. The second plate is supported spaced from the base by a shaft in a chamber of the second plate and a spring. During the heating phase, the second plate is spaced apart from the first plate. During the cooling phase, the second plate is urged by the spring into contact with the first plate, so that the second plate acts as a heat sink for the first plate. Vacuum suction and an annular elastomer seal around the top rim of the second plate clamp the first and second plates together in thermal communication. Vacuum suction in the chamber retracts the second plate from the first plate.

摘要： Gate valve having a closure member mounted on a swinging arm pivotally mounted for movement transversely of the axis of the valve openings. A wedge member carried by the arm drives the closure member in a direction parallel to the axis of the openings when moved longitudinally of the arm. An actuator pivots a cam which bears against the wedge member to swing the arm to a predetermined position in which the closure member is aligned with the openings and thereafter to move the cam to drive the closure member axially and seal one of the openings. Resilient members urge the closure member toward its retracted position and prevent the wedge member from moving forward until the arm reaches the predetermined position.

摘要： A switching power supply with the increased efficiency at light load has a switching power circuit, a power monitoring circuit and a light load power supplying circuit. The switching power circuit converts an AC power to a stable DC power and sends the DC power to a load according to voltage variation of the load. When the power monitoring circuit detects the AC power and determines that the load is in a light state, the power monitoring circuit controls the light load power supplying circuit to output a small-power DC to the load. As the DC power provided by the light load power supplying circuit is small, the switching loss ratio is lower in its light load state. Therefore, the operating efficiency at the light load state is higher.
