摘要： A system and method for reducing power consumption of memory chips outside of a host processor device inoperative communication with the memory chips via a memory controller. The memory can operate in modes, such that via the memory controller, the stored data can be localized and moved at various granularities, among ranks established in the chips, to result in fewer operating ranks. Memory chips may then be turned on and off based on host memory access usage levels at each rank in the chip. Host memory access usage levels at each rank in the chip is tracked by performance counters established for association with each rank of a memory chip. Turning on and off of the memory chips is based on a mapping maintained between ranks and address locations corresponding to sub-sections within each rank receiving the host processor access requests.

摘要： A data processing system includes a processor core and a cache memory hierarchy coupled to the processor core. The cache memory hierarchy includes at least one upper level cache and a lowest level cache. A memory controller is coupled to the lowest level cache and to a system memory and includes a physical write queue from which the memory controller writes data to the system memory. The memory controller initiates accesses to the lowest level cache to place into the physical write queue selected cachelines having spatial locality with data present in the physical write queue.

摘要： A mechanism is provided for dynamic cache allocation using a cache hit rate. A first cache hit rate is monitored in a first subset utilizing a first allocation policy of N sets of a lower level cache. A second cache hit rate is also monitored in a second subset utilizing a second allocation policy different from the first allocation policy of the N sets of the lower level cache. A periodic comparison of the first cache hit rate to the second cache hit rate is made to identify a third allocation policy for a third subset of the N-sets of the lower level cache. The third allocation policy for the third subset is then periodically adjusted to at least one of the first allocation policy or the second allocation policy based on the comparison of the first cache hit rate to the second cache hit rate.

摘要： A mechanism is provided for weighted history allocation prediction. For each member in a plurality of members in a lower level cache, an associated reference counter is initialized to an initial value based on an operation type that caused data to be allocated to a member location of the member. For each access to the member in the lower level cache, the associated reference counter is incremented. Responsive to a new allocation of data to the lower level cache and responsive to the new allocation of data requiring the victimization of another member in the lower level cache, a member of the lower level cache is identified that has a lowest reference count value in its associated reference counter. The member with the lowest reference count value in its associated reference counter is then evicted.

摘要： Systems and methods are provided that schedule task requests within a computing system based upon the history of task requests. The history of task requests can be represented by a historical log that monitors the receipt of high priority task request submissions over time. This historical log in combination with other user defined scheduling rules is used to schedule the task requests. Task requests in the computer system are maintained in a list that can be divided into a hierarchy of queues differentiated by the level of priority associated with the task requests contained within that queue. The user-defined scheduling rules give scheduling priority to the higher priority task requests, and the historical log is used to predict subsequent submissions of high priority task requests so that lower priority task requests that would interfere with the higher priority task requests will be delayed or will not be scheduled for processing.

摘要： A support cradle for supporting a person seated in a chair by cradling the upper legs of the person, and maintaining the legs in a desired passive restraint arranged so that if the person moves the hips or legs in an abnormal degree such as excessive hip flexion, hip adduction, hip internal rotation, hip extension, scissoring or the like, the cradle will restrain such movement. The cradle provides no restraint so long as normal sitting posture is maintained. The cradle is especially useful in treatment and management of patients with neurogenic movement disorders which manifest with spasticity and abnormal movement patterns such as with spinal cord injury or in cerebral palsy.

摘要： A data processing system includes a multi-level cache hierarchy including a lowest level cache, a processor core coupled to the multi-level cache hierarchy, and a memory controller coupled to the lowest level cache and to a memory bus of a system memory. The memory controller includes a physical read queue that buffers data read from the system memory via the memory bus and a physical write queue that buffers data to be written to the system memory via the memory bus. The memory controller grants priority to write operations over read operations on the memory bus based upon a number of dirty cachelines in the lowest level cache memory.
