摘要： A cache memory system includes a cache memory (269, 16A, 17 A, 18A) and a block replacement controller (266). The cache memory may include a plurality of sets, each set including a plurality of block storage locations. The block replacement controller may maintain a separate count value corresponding to each set of the cache memory. The separate count value points to an eligible block storage location within the given set to store replacement data. The block replacement controller may maintain for each of at least some of the block storage locations, an associated recent access bit indicative of whether the corresponding block storage location was recently accessed. In addition, the block replacement controller may store the replacement data within the eligible block storage location pointed to by the separate count value depending upon whether a particular recent access bit indicates that the eligible block storage location was recently accessed.

摘要： A method and apparatus for reducing a page replacement time in a system using a demand paging technique are provided. The apparatus includes a memory management unit (320) which transmits a signal indicating that a page fault occurs, a device driver (340) which reads a page having the page fault from a nonvolatile memory (402), and a page fault handler (310) that searches and secures a space for storing the page having the page fault in a memory (350). The searching and securing of the space in the memory is performed within a limited time calculated beforehand and a part of data to be loaded to the memory of the system is stored in the nonvolatile memory.

摘要： The present invention relates to a main memory space reclaiming apparatus used in a virtual memory computer system. In this apparatus, a page-out daemon process (20) periodically scans page frames of a main memory (30) and reclaims main memory pages which have not been accessed recently. An operating system (10) includes a unit for acquiring the amount of free main memory (30), and a unit for controlling a rate at which the page-out daemon process (20) scans the page frames according to the amount of free main memory (30).

摘要： Methods and apparatus are set forth for use with a cache memory resource (that includes a plurality of cache blocks for storing data) and a cache directory (for keeping track of which of said blocks are in use, the number of times each block is referenced and block age), for determining which of said plurality of cache blocks is to be replaced with data to be stored in cache memory on a cache miss. The methods and apparatus cause a reference count, for each cache block, to be maintained in the cache directory; utilize at least one preselected age boundary threshold to determine when to adjust a reference count for a given block on a cache hit; and select a cache block for replacement as a function of reference count value and block age. For example, when 2 preselected age boundary thresholds are utilized, blocks may be considered for replacement only if they have aged past the second boundary and have a reference count below a preselected threshold value. On a cache miss, the block to be replaced can be selected from the set of blocks whose reference counts are below a preselected reference count threshold value thereby allowing for the possibility of non least recently used block replacement choices. Furthermore, according to another embodiment of the invention, to facilitate rapid identification of possible block replacement choices, a chain of blocks is maintained for each reference count below a preselected reference count threshold value.

摘要： A method for feature reduction in a training set for a learning machine such as a Support Vector Machine (SVM). In one embodiment the method includes a step (35) of receiving input training data vectors x i of a training set. The input training data vectors are typically derived from a set of features in a feature space. At step (37) the input data vectors are mapped into a multi-dimensional space. At step (39) a least squares problem, derived from a formulation of the SVM, is solved to determine which features comprising the training vectors are to be deemed significant. At step (41) decision parameters and vectors of the chosen decision machine, e.g. SVM, are determined using the features determined to be significant in step (39).

摘要： A cache memory comprises ways (0 to 3) and a control unit. For each cache entry, the ways (0 to 3) store a usage flag U to indicate whether an access is made or not. When a hit occurs, the control unit updates the usage flag U corresponding to the cache entry to the one indicating that an access is made. At this time, if all the other usage flags in the set each indicate that an access is made, the control unit resets all the other usage flags in the set to the ones each indicating that no access is made and, from the cache entries corresponding to the usage flags each indicating that no access is made, selects a cache entry to be replaced.
