摘要： An integrated circuit (203) for use in processing streams of data generally and streams of packets in particular. The integrated circuit (203) includes a number of packet processors (307, 313, 303), a table look up engine (301), a queue management engine (305) and a buffer management engine (315). The packet processors (307, 313, 303) include a receive processor (421), a transmit processor (427) and a risc core processor (401), all of which are programmable. The receive processor (421) and the core processor (401) cooperate to receive and route packets being received and the core processor (401) and the transmit processor (427) cooperate to transmit packets. Routing is done by using information from the table look up engine (301) to determine a queue (215) in the queue management engine (305) which is to receive a descriptor (217) describing the received packet's payload.

摘要： Techniques for switching or parking threads in a processor including a plurality of processor cores that share a microcode engine are disclosed. In a dual-core or multi-core system, a front end, (e.g., microcode engine), of the processor cores may be shared by the two or more active threads in order to reduce the area, cost, or the like. A currently running thread may be put to a sleep state and execution of another thread may be initiated when a yield microcode command issues while the currently thread is running. The thread may be resumed on a condition that the second thread goes to a sleep state, yields, exits the processing, etc. Alternatively, a thread may be put to a sleep state when a sleep microcode command issues which is programmed to occur when the thread needs to wait for an event to occur.

摘要： Controlled, high-power laser oscillator. A single laser gain medium is used to efficiently generate high-power, controlled laser light without exposing the control elements to high-power radiation. The control element or elements are separated from the oscillator gain volume by a separator optic which permits only a portion of the energy from the gain volume to enter the region of the control elements, laser light having the desired characteristics being returned to the gain volume through the separator optic. Energy not entering the control region exits the laser as oscillator output energy in order to obtain high efficiency.

摘要： Multiple discharge gas laser apparatus. A compact apparatus for simultaneously or individually generating a plurality of laser output beams in a selected pattern suitable for marking objects, for communications, or for remote chemical sensing or other remote sensing applications, among other uses, where all of the electrodes providing lasing gas excitation are located in a single gas volume and share a single output coupler is described. In this manner, all of the output beams are parallel in far field, to the extent variations in mode structure permit, without the necessity of undertaking detailed optical adjustments. Moreover, the focal plane of the output laser radiation is insensitive to significant positional variation of focusing optics utilized to increase the intensity thereof for marking purposes. Electrodes can be utilized for more than one discharge; that is, the direction of the discharge can be selected to involve any adjacent electrode having opposite charge polarity.

摘要： Uniform, transverse electrical discharges are produced in gaseous media without the necessity of switching the main discharge voltage with an external device which carries the entire discharge current. A three-electrode low pressure discharge tube is charged across its anode (1) and cathode (2) to below breakdown voltage using a dc voltage source (3). An array of resistors (4) or capacitors can be made to discharge to the wire screen anode by means of a low energy high voltage pulse circuit (5) producing sufficient preionization in the region between the anode and cathode to initiate and control the main discharge. The invention has been demonstrated to be useful as a CO.sub.2 laser oscillator and pulse-smoother. It can be reliably operated in the sealed-off mode.

摘要： A technique for handling a conditional move instruction in an out-of-order data processor. The technique involves detecting a conditional move instruction within an instruction stream, and generating multiple instructions according to the detected conditional move instruction. The technique further involves replacing the conditional move instruction within the instruction stream with the generated multiple instructions. The generated multiple instructions are generated such that each of the generated multiple instructions executes using no more than two input ports of an execution unit. The generated multiple instructions include a first generated instruction that produces a condition result indicating whether a condition exists, and a second generated instruction that inputs the condition result as a portion of an operand which identifies a register of the out-of-order data processor. The second generated instruction performs a first move operation when the condition is determined to exist, and a second move operation when the condition is determined not to exist.

摘要： A technique for predicting the result of a conditional branch instruction for use with a processor having instruction pipeline. A stored predictor is connected to the front end of the pipeline and is trained from a truth based predictor connected to the back end of the pipeline. The stored predictor is accessible in one instruction cycle, and therefore provides minimum predictor latency. Update latency is minimized by storing multiple predictions in the front end stored predictor which are indexed by an index counter. The multiple predictions, as provided by the back end, are indexed by the index counter to select a particular one as current prediction on a given instruction pipeline cycle. The front end stored predictor also passes along to the back end predictor, such as through the instruction pipeline, a position value used to generate the predictions. This further structure accommodates ghost branch instructions that turn out to be flushed out of the pipeline when it must be backed up. As a result, the front end always provides an accurate prediction with minimum update latency.
摘要翻译：一种用于预测与具有指令流水线的处理器一起使用的条件转移指令的结果的技术。存储的预测器连接到管道的前端，并且从连接到管道后端的基于真实的预测器训练。存储的预测器可以在一个指令周期中访问，因此提供最小预测器延迟。通过将多个预测存储在由索引计数器索引的前端存储的预测器中来最小化更新延迟。由后端提供的多个预测由索引计数器索引，以选择特定的预测作为给定指令流水线周期上的当前预测。前端存储的预测器还将传递到后端预测器，例如通过指令流水线，用于产生预测的位置值。这种进一步的结构可以容纳重影分支指令，当它必须被备份时，这些指令将被清除流出管道。因此，前端总是以最小的更新延迟提供准确的预测。

摘要： The method and device of the instant invention is a detector of pulsed laser radiation which utilizes the electromotive force generated by the plasma formed when such radiation is focused onto a surface (1). Measurements are made with a 10.6 .mu.m CO.sub.2 laser capable of producing peak intensities of 10.sup.13 W/cm.sup.2 when directed through a converging lens (2). Evacuated detector response to such laser intensity is 1 kV signal peak amplitude and subnanosecond risetimes into a 50.OMEGA. load (3). Detector performance is found to be greatly altered with the introduction of a background gas (4). For example, with one atmosphere of air, the detector produces prompt signals of the order of 1 V with subnanosecond response for pulse trains lasting 100 ns. With argon, krypton, or zenon at pressures of the order of 10 torr, the detector generates "trigger pulses" of about 250 V amplitude and 0.2 ns risetimes. Such detectors are quite robust when irradiated with high intensity laser radiation and are useful for qualitative laser beam monitoring.
