In a multi-core processor system, cache memories are provided respectively for a plurality of processors. An assignment management unit manages assignment of tasks to the processors. A cache status calculation unit calculates a cache usage status such as a memory access count and a cache hit ratio, with respect to each task. A first processor handles a plurality of first tasks that belong to a first process. If computation amount of the first process exceeds a predetermined threshold value, the assignment management unit refers to the cache usage status to preferentially select, as a migration target task, one of the plurality of first tasks whose memory access count is smaller or whose cache hit ratio is higher. Then, the assignment management unit newly assigns the migration target task to a second processor handling another process different from the first processor.

There is provided a magnetic antenna and an antenna device that increase the packaging density of a portion where the magnetic antenna is mounted in an electronic apparatus, and suppresses degradation of antenna performance. A flexible substrate has first and second substantially spiral-shaped coil conductors formed thereon. Conductor-opening-side through holes are formed in the respective conductor openings of the coil conductors, and non-coil-conductor-forming-area through holes are formed in areas in which the coil conductors are not formed. First and second magnetic cores are arranged so as to extend through the respective conductor-opening-side through holes from a first main surface of the flexible substrate and to extend through the respective non-coil-conductor-forming-area through holes in a direction from a second main surface side to the first main surface of the flexible substrate.

The invention relates to a channel equalization method and a channel equalization system based on an RLS (recursive least square) and LMS (least mean square) combined algorithm. The method includes: step 101), training tapping coefficients of an equalizer on the basis of training data by an RLS equalization algorithm until the equalizer reaches convergence, and assuming that the equalizer reaches convergence when the training data are subjected to Ncth iteration; step 102), iterating the 'jth' bit of received user data, windowing an error value acquired by iteration, and calculating an average error autocorrelation estimation value of data, with a fixed length, in a sliding window; step 103), comparing the acquired average error autocorrelation estimation value with a preset threshold value, and selecting one of equalization algorithms including the RLS equalization algorithm and an LMS algorithm; step 104), equalizing the jth user data by the selected equalization algorithm, updating j as j+1, and then returning to the step 102) until all received user data are processed. The channel equalization method and the channel equalization system have the advantages that excellent performance in time-varying channels is achieved, and requirements on real-time performance can be met.
