20110285730 | Controlling Display Updates For Electro-Optic Displays - A display controller may include a display update controller that may cause a color processing operation to be initiated in response to completion of an image data transmission, or a display update operation to be initiated in response to completion of the color processing operation. The display update operation may include updating display pixels of a display matrix of an electro-optic display device. A collision detector may determine whether a waveform for updating a display state of a particular display pixel has finished. The display update controller may cause the particular display pixel to be omitted from a display update operation if the waveform for updating the display state of the particular display pixel has not finished. A second display update operation may automatically be initiated when the waveform for updating the display state of the particular display pixel has finished. | 2011-11-24 |
20110285731 | Mechanism for Granting Controlled Access to a Shared Resource - Disclosed are methods and systems for granting an application-specific integrated circuit (ASIC) in a multi-ASIC environment controlled access to a shared resource. A system includes a first ASIC, a second ASIC, and a shared memory that stores a shared resource and a data set partitioned into fields. The first ASIC writes data to a first subset of the fields and reads data from the fields. The first ASIC includes first logic that computes a first value based on the data read from the fields. The second ASIC writes data to a second subset of the fields and reads data from the fields. The second ASIC includes second logic that computes a second value based on the data read from the fields. Based on the first and second values respectively computed by the first and second logic, only one of the first and second ASICs gains access to the shared resource. | 2011-11-24 |
20110285732 | DATA COMPRESSION AND FILE SEGMENTATION IN DIRECTMODEL JT DATASTORES - The size of lightweight JT data files containing CAD data is reduced by employing loony compression where acceptable for portions of the CAD data, such as 3D geometry data Dictionary-based lossless compression for the remaining portions is augmented by exploiting common repeated structures for some portions, such as precise Brep data, and compressing separate but similar data, such as all metadata for a given part and all scene graph data, together as a single block. The compressed data is then written in separate, uniquely identified data segments indexed in a table of contents, allowing quick access to any data segment for streaming. | 2011-11-24 |
