  • Patent number: 7743233
    Abstract: Disclosed are embodiments of a system, methods and mechanism for management and translation of mapping between logical sequencer addresses and physical or logical sequencers in a multi-sequencer multithreading system. A mapping manager may manage assignment and mapping of logical sequencer addresses or pages to actual sequencers or frames of the system. Rationing logic associated with the mapping manager may take into account sequencer attributes when such mapping is performed Relocation logic associated with the mapping manager may manage spill and fill of context information to/from a backing store when re-mapping actual sequencers. Sequencers may be allocated singly, or may be allocated as part of partitioned blocks. The mapping manager may also include translation logic that provides an identifier for the mapped sequencer each time a logical sequencer address is used in a user program. Other embodiments are also described and claimed.

  • Publication number: 20100078062
    Abstract: A light collection system including a light concentrating device and a reflective curving-surface device is provided. The light concentrating device receives at least a portion of an incident light and forwardly emits the portion of the incident light after concentrating and passing it through a first focal region, so as to obtain a first-stage output light. The reflective curving-surface device has an entrance aperture for receiving the first-stage output light. The reflective curving-surface device includes a reflective inner curving surface, and at least a portion of the reflective inner curving surface has a second focal region. The first focal region and the second focal region are confocal or approximately confocal within a range. As a result, at least a portion of the first-stage output light is confocally converted into a forwardly emitted second-stage output light.

  • Publication number: 20070134825
    Abstract: A non-mask micro-flow etching process, comprising steps of: moving a nozzle capable of inkjetting an etchant over a substrate capable of being dissolved by the etchant; and inkjetting the etchant on the substrate from the nozzle. Means such as polishing and grinding are used to planarize the substrate by removing the flanges formed on the etched substrate. By the control of the size, the amount, the position, the moving direction and the traveling path of the nozzle, and the control of the droplet volume and the concentration of the etchant, as well as the matching of different substrates to a variety of etchants, micro-cups or micro-channels of any shape and formation can be formed to be adapted to electro-phoretic displays, semiconductor devices or any opto-electronic device requiring micro-structures.

  • Publication number: 20070079301
    Abstract: Embodiments of the invention provide a method of creating, based on an operating-system-scheduled thread running on an operating-system-visible sequencer and using an instruction set extension, a persistent user-level thread to run on an operating-system-sequestered sequencer independently of context switch activities on the operating-system-scheduled thread. The operating-system-scheduled thread and the persistent user-level thread may share a common virtual address space. Embodiments of the invention may also provide a method of causing a service thread running on an additional operating-system-visible sequencer to provide operating system services to the persistent user-level thread.

  • Patent number: 7100029
    Abstract: Performing repeat string operations can include aligning a source data location or a destination data location to a location divisible by a predetermined integer, the aligning including performing a string operation using data having a size equal to the operand size. After aligning, a string operation can be performed using data having a size larger than the operand size. Performing repeat string operations can include issuing a first predetermined number of iterations if an operand size is a predetermined size, and issuing a second predetermined number of iterations otherwise. Performing repeat string operations can include determining that a requested number of iterations in a repeat string operation is within a predetermined multi-number range and issuing exactly the requested number of iterations for any value of the requested number within that range.
