    • The present invention relates to a sound image localizing apparatus for generating a sound image localized in an arbitrarily set three-dimensional direction. The sound image direction setting unit (111) is operable to set a three-dimensional direction to which the sound image is to be localized in accordance with a listener's instruction; the angle conversion unit (112) is operable to convert the direction into a lateral angle (α) and a rising angle (β), each of which serves as a cue for the listener to perceive the direction. The convolution operation unit 116 is operable to obtain lateral angle control information corresponding to the lateral angle (α) from the lateral angle control information storage unit (113), a listener's front direction head-related impulse response from the front direction head-related impulse response storage unit (115), and rising angle difference information corresponding to the rising angle (β) from the rising angle difference information storage unit (114). The convolution operation unit 116 is then operable to convolute the sound source signal with the lateral angle control information, the front direction head-related impulse response, and the rising angle difference information, and output the operation result.
    • 本发明涉及用于产生定位在任意设定的三维方向上的声像的声像定位装置。 声音图像方向设定单元(111)可以根据收听者的指示来设定声像要进行定位的三维方向; 角度转换单元(112)可操作以将该方向转换成横向角(α)和上升角(β),每个角度(β)用作听众感知方向的提示。 卷积运算单元116可操作以获得与横向角度控制信息存储单元(113)相对应的横向角度(α)的横向角度控制信息,来自前方向头部相关脉冲的收听者前方向头部相关脉冲响应 响应存储单元(115),以及与上升角信息存储单元(114)对应的上升角(β)的上升角差信息。 卷积运算单元116然后可操作以使声源信号与横向角度控制信息,前向方位头相关的脉冲响应和上升角差信息进行卷积,并输出运算结果。

    • According to one embodiment, an electronic apparatus includes a housing, a battery pack, an ODD unit having a thickness smaller than the battery pack, and an additional device contained in the housing. The battery pack is arranged in a back section of the housing. The ODD unit is arranged to be one-sidedly shifted to a front section in the housing, and includes a front end portion opposed to the front section, and a back end portion opposed to the battery pack. The additional device is away from the front end portion of the ODD unit, and overlaps the back end portion of the ODD unit in the vertical direction.

    • A schedule control program that is capable of allocating threads to CPUs so as to effectively use caches. When a thread is executed, the execution start time and the CPU number of a CPU that executes the thread are stored. When an interrupted thread is re-allocated to a CPU to execute it next, an elapsed time t counted from the execution start time is calculated. Time parameters are set to caches that are used by the CPUs in such a way that the higher the level of a cache, the larger time parameter is set. If the elapsed time t is smaller than a time parameter set to a n-level (n is a natural number of 2 or greater) cache and is equal to or larger than a time parameter set to a (n−1)-level cache, the thread is allocated to a CPU with the lowest load among the CPUs sharing the n-level cache with the last execution CPU.
    • 一种能够向CPU分配线程以便有效地使用高速缓存的时间表控制程序。 当执行线程时,执行线程的执行开始时间和CPU号码被存储。 当中断的线程被重新分配给CPU以执行它时,计算从执行开始时间开始的经过时间t。 时间参数设置为CPU使用的高速缓存,缓存级别越高,时间参数越大。 如果经过时间t小于设置为n级(n为2以上的自然数)高速缓存的时间参数,并且等于或大于设置为(n-1)级高速缓存的时间参数 ,在最后一个执行CPU共享n级缓存的CPU中,线程被分配给具有最低负载的CPU。
