    • The sound field reproducing apparatus includes: a signal obtaining unit which obtains input audio signals of plural channels; an effect adding unit which gives an effect on an output to a sound field; and an effect amount control unit which controls an amount of the effect based on a characteristic of the input audio signal. The sound field reproducing apparatus receives input audio signals of plural channels from a medium such as a DVD, and gives a sound effect to them to output. The amount of the effect given to the input audio signal is controlled based on the characteristic of the input audio signal, especially the cross correlation of the reverberation component between the channels.

    • A characteristics measurement device is applicable to various kinds of measurement devices for measuring characteristics subjected to a measurement in a certain environment. The characteristics measurement device measures a noise level in the environment, and determines the noise state based on the obtained noise level. Then, the characteristics measurement device determines the number of times of measurement of the characteristics based on the noise state, and executes synchronized addition of the characteristics obtained by the plural measurements to output the characteristics. Thus, when the noise state in the environment of the measurement execution is preferable, the measurement is completed in the smallest number of times of measurement. Additionally, when the noise state of the environment is not preferable, the plural measurements are executed in order to obtain the desired noise state (e.g., S/N), and the results are synchronized and added. Since the influence of the noise is reduced by repeating the synchronized addition, the measurement result with high accuracy can be obtained. In the environment of the measurement execution, an unexpected noise other than an ordinary noise may occur. If the unexpected noise occurs, measurement accuracy largely becomes low. Then, when a correlation of the plural measurement results is low, it is assumed that the unexpected noise occurs. By increasing the number of times of measurement, the influence of the unexpected noise can be removed.
    • 特性测量装置适用于各种用于测量在某种环境中进行测量的特性的测量装置。 特征测量装置测量环境中的噪声电平,并且基于获得的噪声电平来确定噪声状态。 然后,特性测量装置基于噪声状态确定特性的测量次数,并且执行通过多个测量获得的特性的同步相加以输出特性。 因此,当测量执行的环境中的噪声状态是优选的时,以最小的测量次数完成测量。 此外,当环境的噪声状态不是优选时,执行多个测量以获得期望的噪声状态(例如,S / N),并且结果被同步和相加。 由于通过重复同步加法来降低噪声的影响,因此可以获得高精度的测量结果。 在测量执行的环境中,可能会发生除普通噪声之外的意外的噪音。 如果出现意想不到的噪音,测量精度大大降低。 然后,当多个测量结果的相关性低时,假设出现意外的噪声。 通过增加测量次数,可以消除意想不到的噪音的影响。

    • The present invention discloses a data processing system having a program structure and execution mode where an actual argument is bound to a formal argument of a function to be called by storing a pair of a variable name as the formal argument and a variable as the actual argument into a First-In-Last-Out type stack memory which is an environment list, the function called executes processings using a latest bind value of said environment list when referring to variable values, when a value of such function is obtained, the function value is returned by deleting the formal argument variable of the function from the environment list. The system includes an associative buffer memory provided externally to the stack memory, where at least the variable name and location data of variable on the environment list are stored in the associative buffer memory, and thereby the access time for referring to variables stored in the stack memory can be curtailed.

    • Effective expansion of a common intermediate buffer memory by equivalent use of the buffer memory in each CPU in a multiprocessor system. A method and system for achieving buffer memory coincidence is applied to a multiprocessor system provided with central processing units, buffer memories contained in respective central processing units, a main memory, and an intermediate buffer memory connected between the main memory and the buffer memories, wherein a buffer invalidation address information (BIA GO) is sent from the intermediate buffer memory to the i-th central processing unit (BIA GO #i) in accordance with the following logical expression:BIA GO #i=REQ.CPU.times.W.times.{F.upsilon.F.times.(COPY#i.upsilon.VIF)}where the term "REQ.CPU" indicates that the i-th central processing unit does not provide a request for accessing the intermediate buffer memory, the term "W" indicates that the above request is a request for writing a data block, term "F" and "F" indicate that the accessed data block is found and is not found, respectively, in the intermediate buffer memory, the term "COPY #i" indicates that a copy of the corresponding data block is stored in the buffer memory of the i-th central processing unit, the validity flag term VIF indicates the possibility that the copy flags are incorrect, and the symbols "x" and ".upsilon." represent a logical product and a logical sum, respectively. This method makes it possible to store data blocks which exist only in the buffer memory but do not exist in the intermediate buffer memory.
