摘要： PROBLEM TO BE SOLVED: To restrict an increase of a load of a sound generation allocation processing or a parameter setting processing, etc. even if the number of sound generation channels increases.SOLUTION: CPU allocates, when a note-on is detected, a sound generation unit consisting of two sound generation channels and sets tone control data of the allocated sound generation unit on a sound source register 23. The tone control data includes a parameter that is common to the two sound generation channels of the sound generation unit. When CPU supplies a sound generation start instruction to a sound source part 20, the sound source part 20 accumulates F numbers that are common to the two sound generation channels so as to generate a phase that is common to the two sound generation channels. A waveform reading part 112 reads waveform data of Lch and Rch from the waveform memory 21 based on the phase and respective waveform selecting information of Lch and Rch. Musical sound characteristics of the waveform data of Lch and Rch having been read by the waveform reading part 112 are controlled based in a characteristic control part 113 on a characteristic control parameter that is common to the two sound generation channels.

摘要： PURPOSE:To transfer blocks at a high speed by using a means which extracts prescribed continuous bits out of the data to be transferred and produces 1-word data. CONSTITUTION:The source data SD of a transfer destination which is read out of a VRAM for each byte is inputted to a rotator 16 via a latch 11 and a selector 8 to be rotated in response to the bit address of the transfer destination and temporarily latched by an old data latch 17. Then the following read bytes are also rotated by prescribed rotational frequencies and synthesized by a phase mask logic together with the contents of the latch 17. The SD subjected to synthesis is inputted to a mask logic circuit via a logic arithmetic circuit 12 together with the head byte of the transfer destination to be synthesized in accordance with the contents of a mask register MASKO for the head byte of the transfer destination and outputted for each byte to a VRAM of the transferee.

摘要： PROBLEM TO BE SOLVED: To provide a musical sound generating device which starts generating a new sound without delay. SOLUTION: A register 14 of a sound source means 1 comprises a first buffer group 15 stored with parameters as objects of synchronous writing and a second buffer group 16 stored with parameters other than the objects of synchronous writing. A busy flag is set on during a period of writing of the parameters as the objects of synchronous writing to the first buffer group 15, but it is made possible to access the second buffer group 16 and write/read the parameters other than the objects of synchronous writing.

摘要： PURPOSE:To prevent malfunction of each part of the circuit used for the titled apparatus by using a clock supplied to the 1st input terminal normally as a master clock and using a substitution clock as the master clock in switching the frequency of the master clock. CONSTITUTION:A dot clock pulse DCK and a substitution clock pulse FCK are supplied to input terminals A, B of a selector 20 via terminals T1, T2. In switching the frequency of the clock DCK supplied to the 1st input terminal B, the clock FCK is used with switching. While the clock FCK is used as the master clock, the clock DCK supplied to the 1st input terminal B is switched and then the clock DCK supplied to the 1st input terminal B is outputted as the master clock. Thus, in switching the frequency of the master clock. The level period of the active side of the master clock is not decreased and the malfunction of each part of the circuit is prevented.

摘要： PURPOSE:To increase the arithmetic processing speed by reducing the scale of hardware and flexibly coping with the change of a branch condition and performing the processing in an ALU(arithmetic logic unit) and the branch processing in parallel. CONSTITUTION:An arbitrary value is written in a private comparison register 21 through a DSP bus 12. A value to be compared is outputted to the DSP bus 12. The value on the DSP bus 12 and the value in the comparison register 21 are compared with each other by a comparing operation circuit 22, and it is determined whether the control should be branched or not in a conditional branch circuit 24 based on the comparing operation result and the output of a condition circuit 23 to control the value of a program counter.
