摘要： A halt sequencing protocol permits a context switch to occur in a processing pipeline even before all units of the processing pipeline are idle. The context switch method based on the halt sequencing protocol includes the steps of issuing a halt request signal to the units of a processing pipeline, monitoring the status of each of the units, and freezing the states of all of the units when they are either idle or halted. Then, the states of the units, which pertain to the thread that has been halted, are dumped into memory, and the units are restored with states corresponding to a different thread that is to be executed after the context switch.

摘要： A context switch request is made from a host unit to a processing engine separately from the method stream to that processing engine and does not require the host unit to know what context the processing engine is currently working on. Upon receiving the request, the processing engine compares the requested context with the context that it is currently working on, and if the two are different, performs the context switch to the requested context. On the other hand, if the two are the same, the engine does not perform the context switch and continues working on the current context.
摘要翻译： 上下文切换请求从主机单元到处理引擎，与方法流分离到该处理引擎，并且不要求主机单元知道处理引擎当前正在工作的上下文。 在接收到请求时，处理引擎将所请求的上下文与其当前工作的上下文进行比较，如果两者不同，则执行上下文切换到所请求的上下文。 另一方面，如果两者相同，则引擎不执行上下文切换并继续在当前上下文中工作。

摘要： Processing units are configured to capture the unit state in unit level error status registers when a runtime error event is detected in order to facilitate debugging of runtime errors. The reporting of warnings may be disabled or enabled to selectively monitor each processing unit. Warnings for each processing unit are propagated to an exception register in a front end monitoring unit. The warnings are then aggregated and propagated to an interrupt register in a front end monitoring unit in order to selectively generate an interrupt and facilitate debugging. A debugging application may be used to query the interrupt, exception, and unit level error status registers to determine the cause of the error. A default error handling behavior that overrides error conditions may be used in conjunction with the hardware warning protocol to allow the processing units to continue operating and facilitate in the debug of runtime errors.

摘要： A unit status reporting protocol may also be used for context switching, debugging, and removing deadlock conditions in a processing unit. A processing unit is in one of five states: empty, active, stalled, quiescent, and halted. The state that a processing unit is in is reported to a front end monitoring unit to enable the front end monitoring unit to determine when a context switch may be performed or when a deadlock condition exists. The front end monitoring unit can issue a halt command to perform a context switch or take action to remove a deadlock condition and allow processing to resume.

摘要： A method and system for using bundle decoders in a processing pipeline is disclosed. In one embodiment, to perform a context switch between a first process and a second process operating in a processing pipeline, the first state information that is associated with the first process is placed on a connection separate from the processing pipeline. A number of decoders are coupled to this connection. The decoders obtain the first state information from a number of pipeline units on the processing pipeline by monitoring the data stream going into these pipeline units. Also, to restore the first state information after having switched out the second state information that is associated with the second process, the first state information is placed on the connection for the decoders to retrieve.

摘要： In a processing pipeline having a plurality of units, an interface unit is provided between a first, upstream pipeline unit that needs to be drained prior to a context switch and a second, downstream pipeline unit that might halt prior to a context switch. The interface unit redirects data that are drained from the first pipeline unit and to be received by the second pipeline unit, to a buffer memory provided in the front end of the processing pipeline. The contents of the buffer memory are subsequently dumped into memory reserved for the context that is being stored. When the processing pipeline is restored with this context, the data that were dumped into memory are retrieved back into the buffer memory and provided to the interface unit. The interface unit receives these commands and directs them to the second pipeline unit.

摘要： A micromirror array assembly (10, 20) for use in optical modules (5, 17) in a wireless network system is disclosed. The micromirror array assembly (10, 20) includes a plurality of mirrors (29) monolithically formed with a frame (43), attached by way of hinges (55) and gimbal portions (45). Permanent magnets (53) are attached to each of the gimbal portions (45) associated with the mirrors (29). The resulting frame (43) is then mounted to a coil driver assembly (50) so that coil drivers (34) can control the rotation of each mirror (29), under separate control from control circuitry (14, 24). The micromirror array assembly (10, 20) is thus able to support higher signal energy at larger spot sizes, and also enables multiplexed transmission and receipt, as well as sampling of the received beam for quality sensing. A method of manufacturing the micromirror array assembly (10, 20) is also disclosed, in which a support wafer (60) is temporarily bonded to the mirror wafer (70) while the permanent magnets (53) are attached.

摘要： A surface plasmon resonance (SPR) sensor includes a transparent base housing 12 and a detachable optical housing 19. Radiation from a radiation source 10, disposed within base housing 12, is polarized by polarizing filter 16 and passes through the interface between base housing 12 and optical housing 19. The polarized radiation 18 is reflected from a mirror 20 onto a SPR layer 22, which is formed on an exterior surface of optical housing 19. Layer 22 comprises a thin layer of a conductive material. Radiation 24 reflected from SPR layer 22 re-enters housing 19 and strikes an array 28 of photodetectors. From the intensity of radiation at each photodetector, one can determine the index of refraction of the substance on the opposite side of SPR layer 22.
