  • Patent number: 8099585
    Abstract: Full predication of instruction execution is provided by operand predicates, where each operand has an associated predicate bit intuitively indicating the validity of the operand value. In a programmable processor supporting operand predication, an instruction will execute only if the predicate bit of every register containing a source operand is true. The predicate bit, if any, of the destination register is set to the logical AND of the source registers' predicates. Similarly, in a non-programmable processor synthesized with predicated operand support, an operator will perform the associated function depending on the state of inputs' predicates. The output predicate is evaluated as the logical AND of the inputs' predicates. An additional bit for each data register, a change in the semantics of the instructions to include predication, and a few additional instructions to save and restore register predicate bits and to specifically set or reset a register's predicate bit are required.

  • Patent number: 8099545
    Abstract: A wear leveling solution is proposed for use in a storage device based on a flash memory. The flash memory includes a plurality of physical blocks, which are adapted to be erased individually. A corresponding method starts with the step for erasing one of the physical blocks. One of the physical blocks being allocated for storing data is selected; this operation is performed in response to the reaching of a threshold by an indication of a difference between a number of erasures of the erased physical block and a number of erasures of the selected physical block. At least the data of the selected physical block being valid is copied into the erased physical block. The selected physical block is then erased.

  • Publication number: 20120008603
    Abstract: Contention based period beamforming includes the establishment of synchronized communications between a beamforming initiator and a beamforming responder to precisely define a start time for beamforming training. Synchronization between the beamforming initiator and beamforming responder begins with the sending of control information to the responder so that the start of the beamforming process will be synchronized. With beamforming training synchronized, beamforming is initiated using the sector sweep process.

  • Publication number: 20120008004
    Abstract: A lighting identification chart has a grey patch lighting identification feature and a three-part fiduciary marker positioned around the grey patch. The lighting identification chart 102 can be a small 18% reflectance ‘grey card’ produced with a fiduciary marker pattern on its surface. An imaging algorithm determines the orientation of the card with respect to the camera and locates the area of the grey patch. During image capture, the subject presents the card within the frame. The camera recognizes the locating features and calculates a white balance based on the grey patch on the card.

  • Publication number: 20120007871
    Abstract: An electronic system, an integrated circuit and a method for display are disclosed. The electronic system contains a first device, a memory and a video/audio compression/decompression device such as a decoder/encoder. The electronic system is configured to allow the first device and the video/audio compression/decompression device to share the memory. The electronic system may be included in a computer in which case the memory is a main memory. Memory access is accomplished by one or more memory interfaces, direct coupling of the memory to a bus, or direct coupling of the first device and decoder/encoder to a bus. An arbiter selectively provides access for the first device and/or the decoder/encoder to the memory based on priority. The arbiter may be monolithically integrated into a memory interface. The decoder may be a video decoder configured to comply with the MPEG-2 standard. The memory may store predicted images obtained from a preceding image.

  • Publication number: 20120010504
    Abstract: A device for correlating trend data with respect to a patient's weight ankle displacement can identify conditions indicative of congestive heart failure. A weight scale or similar device coupled with imaging mechanism operable to measure ankle displacement collects a plurality of measurements over a period of time. Over time trend analysis of both the patient's weight and the ankle displacement measurements can be obtained and compared to identify whether over a particular sample period an increase in a patient's ankle displacement is or is not correlated with an increase in the patient's weight. When an increase in ankle displacement is identified as not correlating to a corresponding change in the patient's weight an alert can be issued of conditions indicative of congestive heart failure.
