    • A wave generating method and a wave generating apparatus using the method are arranged such that plurality of wave samples, each being generated successively, are respectively weighted by, for example, being multiplied by a plurality of wave functions generated corresponding to the plurality of wave samples. The plurality of weighted wave samples are summed to obtain a desired wave. The kind of each of the plurality of wave samples generated successively is changed at each time when the value of corresponding one of the plurality of wave functions becomes zero. Therefore, the apparatus includes wave generators for generating the wave samples successively, wave function generators for generating the wave functions successively, multipliers for multiplying the wave samples by the wave functions respectively, an adder for adding all of the outputs of the multipliers to generate the desired wave, and a wave changing circuit for changing the kind of each of the wave samples when the corresponding one of the wave functions becomes zero.
    • 使用该方法的波形生成方法和波形发生装置被布置成使得依次生成的多个波形样本分别通过乘以与多个波形样本相对应的多个波函数相乘来加权 。 将多个加权波样本相加以获得期望的波。 在多个波函数中的相应一个的值变为零的时刻,连续地生成的多个波形样本中的每一个的样本的种类都变化。 因此,该装置包括连续产生波形样本的波形发生器,连续产生波函数的波函数发生器,用于将波样本乘以波函数的乘法器,用于将乘法器的所有输出相加的乘法器, 期望波,以及波形变换电路,用于当相应的一个波函数变为零时,改变每个波形样本的种类。

    • An electronic apparatus includes a controller having an interface part communicating with an external host apparatus and a status register group, and having a plurality of functional units communicating with the host apparatus via the interface part, respectively. The status register group includes operable status registers corresponding to the functional units respectively and indicating whether or not the corresponding functional units are in an operable state, and processing status registers corresponding to the functional units respectively and indicating whether or not the corresponding functional units are in a Function-Being-Processed State. When a command received from the host apparatus is provided for any one of the functional units, the controller transfers the command to the functional unit. In the case of a read command for the status register group, the controller transmits a status of the status register group to the host apparatus as a response.
