    摘要: A translation look-aside buffer (TLB) capable of reducing power consumption and improving performance of a memory is provided. The fully-associative TLB which converts a virtual address into a physical address, comprises a first TLB having a plurality of banks; a second TLB having a plurality of entries, each of which having one virtual page number and 2N physical page numbers, wherein N is a natural number; and a selection circuit for outputting an output signal of the first TLB to the second TLB in response to a selection signal, wherein each bank of the first TLB has a plurality of entries, each of which has one virtual page number and one physical page number. The size of a page indicated by a virtual page number of the first TLB is different from the size of a page indicated by a virtual page number of the second TLB.

    摘要: An image search method may include: determining a quadrant of a predicted motion vector; calculating a tilt value of a first reference frame and a tilt value of a second reference frame using the predicted motion vector; deciding a search area for uneven hexagon search in response to the quadrant of the predicted motion vector and the calculated tilt values; performing the uneven hexagon search with respect to the decided search area; and/or comparing a result of the performed uneven hexagon search with a threshold value to determine termination of the uneven hexagon search. The second reference frame is earlier-in-time relative to the first reference frame.

    摘要: A resource sharing method for a resource sharing system for a plurality of edge peers that individually store a resource and a plurality of super peers that manage the plurality of edge peers or resource information including a name of the resource that includes at least one key word is provided. In the resource sharing system, the super peers distribute and manage resource information of the edge peers according to a key word. Therefore, if a resource is requested using part of a name of a resource desired by a certain edge peer, the super peer searches for resources including the resource desired by the edge peer. Therefore, a user of an edge peer may acquire a desired resource even using part of a name of a desired resource.

    摘要: A cache memory system reduces the rate of cache misses. The cache memory system includes a first auxiliary storage device which stores first information blocks and a second auxiliary storage device which stores second information blocks fetched from a lower level memory device. Each second block includes a plurality of the first information blocks. A process for fetching information selectively fetches a first or second information block from the lower level memory device and selectively stores the fetched block in the first auxiliary storage device and/or the second auxiliary storage device. Selection of the size of block to fetch and where to store the fetched block is according to whether the data to be referenced by the central controller is in the first auxiliary storage device or the second auxiliary storage device and whether first information blocks that do not include the referenced data are both in the second information block including the referenced data and in the first auxiliary storage device. A control unit that controls the selective fetching and storing maintains state data that includes entries corresponding to second information blocks. Each entry identifies a corresponding second information block and indicates the number of first information blocks that are in the first auxiliary storage device and from the corresponding second information block.
