摘要： A virtual memory system that maintains a list of pages that are required to be resident in a frame buffer to guarantee the eventual forward progress of a graphics application context running on a graphics system composed of multiple clients. Pages that are required to be in the frame buffer memory are never swapped out of that memory. The required page list can be dynamically sized or fixed sized. A tag file is used to prevent page swapping of a page from the frame buffer that is required to make forward progress. A forward progress indicator signifies that a page faulting client has made forward progress on behalf of a context. The presence of a forward progress indicator is used to clear the tag file, thus enabling page swapping of the previously tagged pages from the frame buffer memory.

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 device may store information associated with a group of items in a database. The information associated with a particular item may include a group of versions of a particular attribute. A particular version of the particular attribute may include a value associated with the particular attribute and a timestamp. The device may receive a query that specifies a time; determine that the query is associated with the particular item; and determine, based on the specified time, which version of the particular attribute is associated with the query. The device may determine which version of the particular attribute is associated with the query by identifying, based on the timestamps associated with the versions of the particular attribute, a version of the particular attribute that is a newest version, of the versions of the particular attribute that are associated with timestamps that are before or concurrent with the specified time.

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.

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.
