    摘要： A method for processing a digital signal produced by digitizing an analog signal such as a musical instrument sound signal, and an apparatus for producing sound source data. When the input signal contains a periodically repetitive waveform portion, the fundamental frequency and its high harmonic components of the input signal is extracted by a comb filter prior to signal processing which takes advantage of the periodicity of the input signal. The fundamental frequency or pitch is detected by performing Fourier transform to produce frequency components, phase matching these frequency components and performing inverse Fourier transform. When extracting a repetitive waveform portion or so-called looping domain, such looping domain having the highest similarity in waveform in the vicinity of both ends of the domain is selected. When the bit compression of digital signal data is performed by selecting a filter with blocks each consisting of plural samples as units, a pseudo signal is affixed to the input signal, before the start point of the input signal, which pseudo signal will cause a filter of the lowest order to be selected. The looping domain is set so as to be a whole number multiple of the block which serves as the unit for bit compression, and the parameters of the looping start block are formed on the basis of data of the start and the end blocks. By applying a part or the whole of the signal processing method to a sound source data forming apparatus, sound source data may be formed which is reduced in the looping noise and error caused by data compression and which is of superior sound quality.

    摘要： Logical addresses start from different base addresses for respective numbers of bits of data making up words. One physical address in a main memory corresponds to a plurality of logical addresses, and an address converter has an association table of physical and logical addresses. The address converter decides which base address an entered logical address belongs to for thereby determining the number of bits of data of one word, and determines a physical address so as to be able to read words corresponding to the number of bits from the main memory. Words made up of different numbers of bits can quickly be converted from logical addresses into physical addresses.

    摘要： An apparatus for generating the interrupt information includes an addressing device for generating the specified address information for specifying the desired information stored in a memory device, a readout address generating device for generating the readout address information of the desired information stored in the memory device, and a comparator device for comparing the specified address information from the addressing device and the readout address information from the readout address generating device and for generating the interrupt information in case of coincidence of the specified address information and the readout address information and supplying the interrupt information to a central processing unit. Since the interrupt data is supplied to the central processing unit at the playback timing of the desired sound source data, reproduction of the sound source data can be detected, so that it is unnecessary for the central processing unit to poll the address of the sound source data at all time and hence the load imposed on the central processing unit may be correspondingly decreased.
