<P>PROBLEM TO BE SOLVED: To provide a sound generator apparatus processing at high speed and reconfiguring functions dynamically. <P>SOLUTION: The sound generator apparatus 100 includes: an operation section A for executing a plurality of types of instructions by performing arithmetic operations using a plurality of hardware-implemented arithmetic operation elements; and a control section B for reading out a program from a program memory 84 to execute the read-out program. The plurality of types of instructions include: a first extended instruction for instructing that an arithmetic operation for generating envelope data to control variation over time of a sound volume should be performed using data read out from a working memory 83 and the arithmetic operation elements; a second extended instruction for instructing that an arithmetic operation for generating phase data to control a frequency of a waveform should be performed using data read out from a working memory 83 and the arithmetic operation elements; and a third extended instruction for instructing that an arithmetic operation for generating result data should be performed using the envelope and phase data and the arithmetic operation elements. <P>COPYRIGHT: (C)2009,JPO&INPIT |
