摘要： A physical process ID (PPID) is stored for each cache block of each set, and a MAX WAY number for each PPID value is stored for each of index values #1 to #n. A MAX WAY number corresponding to a certain PPID value in a certain index value indicates the maximum number of cache blocks having the PPID value, which can be stored in the index value. The number of ways at the time of a cache miss is controlled not to exceed the MAX WAY number of each PPID value for each index value.

摘要： A program counter control method controls instructions by an out-of-order method using a branch prediction mechanism and controls an architecture having delay instructions for branching. The method includes the steps of simultaneously committing a plurality of instructions including a branch instruction, when a branch prediction is successful and the branch instruction branches, and simultaneously updating a program counter and a next program counter depending on a number of committed instructions.

摘要： A cache controller controls at least one cache. The cache includes ways including a plurality of blocks that stores therein entry data. A writing unit writes degradation data to a failed block. The degradation data indicates that the failed block is in a degradation state. A reading unit reads entry data from a block. A determining unit determines, if the entry data obtained by the reading unit includes the degradation data, that the block is in the degradation state.

摘要： Wire of an oval type cross sectional shape having a surface formed of a semicircle and semiellipse tangent to each other has been used for coiled springs. Stress distribution in wire of such a shape can be improved by increasing the dimension of the spring wire in a direction perpendicular to the axis of the spring. One such cross sectional shape is formed by semicircle and semiellipse portions connected by straight lines.

摘要： A degeneration control device that controls degeneration of a cache having a plurality of ways based on an error that occurs in response to an access request, includes a cache line degeneration information memory unit, which stores cache line degeneration information that indicates whether a cache line constituting each of the plurality of ways is degenerated, and a degeneration control unit, which writes, when an error that occurs in response to the access request causes a predetermined condition to be met, cache line degeneration information that indicates a predetermined cache line where the error occurs is degenerated in the cache line degeneration information memory unit.

摘要： It is known that a sectional shape of a spring wire can be formed into an oval made by a semicircle and a semiellipse. However, it has been found that such a shape is not the best obtainable, and that stress distribution can be improved by increasing the diameter of the spring wire slightly in a portion where the stress is greatest, along the semielliptical surface. Parameters are disclosed for determining dimensions that result in increased energy efficiency.
