摘要： Interconnect-dominated large register files are reduced in chip area and delay time. A register file in a processor having a number of execution units is divided into multiple copies. Different groups of execution units can read from and write to their own copy of the file registers by a set of local read and write ports. All of the register-file copies are synchronized by writing data from the execution units to remote write ports in at least some registers in other copies of the register file. Each copy can be divided into local and global registers. While all copies of the global registers continue to be written by the remote write ports, the local registers can be written only by a local cluster of execution units. Alternatively or additionally, all of the execution units can write to their local register-file copy, but only some of the units can write the global registers in all copies of the register file.

摘要： A system and method for controlling the scheduling of threads in a multi-thread processor system. The multi-thread processor system has a multi-thread processor, a main memory, a cache memory, and a thread scheduler. Information is sent from the cache memory to the thread scheduler for determining which thread the processor is going to execute. The thread scheduler calculates or maintains a figure of merit for each thread executing on the processor. The figure of merit determines which thread to switch to when the current or previous thread has a long latency. The figure of merit define the execution environment as measured by the performance of the cache memory. The figure of merit can be the owner of a particular thread, the number of data lines accessed by a particular thread which resides in the cache, the number of times a particular thread has hit in the cache over a specified time interval, the thread that installed the data or the thread that was used most recently.

摘要： A software system that provides access control to resources and that disassociates access rights to resources from references to resources to prevent the formation of large and unwieldy access control lists and to enable advanced decentralized security controls. The software system includes a repository that holds a resource descriptor for each resource including lock/permission pairs. Access to particular resources or groups of resources is provided by providing users with the appropriate keys. The keys are themselves are resources with resource descriptors in the repository. Access rights for users may be revoked by deleting keys from the repository. The software system also provides visibility fields for compartmentalizing access to resources. In addition, the software system provides authorizers that maintain audit trails when critical resource such as keys are passed among users and that enable advanced security control when passing resources among users.

摘要： The method of prefetching data into cache to minimize CPU stall time uses a rough predictor to make rough predictions about what cache lines will be needed next by the CPU. The address difference generator uses the rough prediction and the actual cache miss address to determine the address difference. The prefetch engine builds a data structure to represent address differences and weights them according to the accumulated stall time produced by the cache misses given that the corresponding address is not prefetched. This stall time is modeled as a loss function of the form: L = ∑ j = 0 n ⁢ ⁢ L ⁢ ⁢ ( x j ) L ⁢ ⁢ ( x j ) = ∑ i = 0 sl ⁡ ( j ) - 1 ⁢ ⁢ C i ⁢ ⁢ ( b j - i , x j ) The weights in the data structure change as the prefetch engine learns more information. The prefetch engine's goal is to predict the cache line needed and prefetch before the CPU requests it.

摘要： An analysis system and method provide for quantitatively evaluating image quality characteristics of an ultrasound imaging machine that evaluates at least one image representation of a standard phantom acquired by the image machine. The machine under test by comparing acquired parameters with prestored values, and returning a determined set of image quality indices, along with a single index representing an arithmetic combination of all other image quality indices, which indicate the accuracy of the test image relative to a “gold standard” that has been pre-established for the model of imaging machine under investigation. The system, which includes a computer-programmed set of instructions and data, optionally includes at least one standard phantom. The image quality indices, or metrics, quantitatively represent an evaluation of a test image using a set of relatively subjective criteria that include homogeneity, contrast, signal attenuation and penetration of depth, pin to background ratio in near and far-field, axial and lateral resolution, modulation transfer function, and geometric distortion, and axial and lateral linearity. These image quality indices are determined by specific algorithms and then combined to form an image health index. The image health index and the individual component indices are compared to a gold standard set of indices obtained from an equivalent imaging machine operating under optimum conditions and settings.

摘要： Locally-adaptive, sub-voxel registration of two volumetric data sets is performed by generating match points and then, using the match points, generating a locally-adaptive image-to-warp transformation. Generation of the match points is accelerated by generating a volume hierarchy and then identifying a set of 3D points in the first volume for designation as interesting points. Interesting points in the first volume are then matched with their corresponding points in the second volume. After performing match point generation, points on a cubic grid in the first volume are matched to the corresponding match points in the second volume by resampling the match points on the cubic grid in the first volume. After a grid of match points has been identified, the displacement (dx, dy, dz) that should be added to each cubic grid point in the first volume to identify the coordinates of the corresponding point in the second volume is determined. Using the displacements in the match points, a warping transformation function that specifies the displacement for each point (x, y, z) in the first volume is determined. The transformation function maps the matched points in the first volume to corresponding points in the second volume by determining the amount of displacement in the x, y and z directions.
