摘要： A mechanism for priority control in resource allocation for low request rate, latency-sensitive units is provided. With this mechanism, when a unit makes a request to a token manager, the unit identifies the priority of its request as well as the resource which it desires to access and the unit's resource access group (RAG). This information is used to set a value of a storage device associated with the resource, priority, and RAG identified in the request. When the token manager generates and grants a token to the RAG, the token is in turn granted to a unit within the RAG based on a priority of the pending requests identified in the storage devices associated with the resource and RAG. Priority pointers are utilized to provide a round-robin fairness scheme between high and low priority requests within the RAG for the resource.

摘要： A method and apparatus are provided for efficiently managing hot spots in a resource managed computer system. The system utilizes a controller, a series of requester groups, and a series of loan registers. The controller is configured to allocate and is configured to reallocate resources among the requestor groups to efficiently manage the computer system. The loan registers account for reallocated resources such that intended preallocation of use of shared resources is closely maintained. Hence, the computer system is able to operate efficiently while preventing any single requestor or group of requesters from monopolizing shared resources.

摘要： Apparatus and method for compressing sequentially related data while fully preserving the informational content of the data. In a preferred form, digital format video image data individualized by pixel is compressed by defining a reference value for a first pixel position, encoding successive pixel values based on offsets from the reference value, and counting the pixels so encoded. Compression is obtained by having the bit count of the encoding be less than the original bit count associated with each pixel value. The reference value or encoding range is adjusted as necessary to retain the informational content of the original image data. The invention also find usage in a multimedia context, where the encoding is based upon a temporal relationship of single or multiple pixels. Full preservation of the original information content is retained throughout.

摘要： A computer implemented method, apparatus, and computer usable medium for gathering performance related data in a multiprocessing environment. Instrumentation code is executed on a processor that minimizes the distortion to the processor resources used to execute the program to be profiled. Data is written by the instrumentation code to a shared memory in response to an event occurring during execution of the program. The data is generated during execution of the program on the processor and the instrumentation code uses shared memory to convey the data to a profiling application running on a set of profiling processors. The data is collected by the set of profiling processors in the shared memory written by the instrumentation code.
