Abstract
A storage of DSP receives and stores a plurality of signal processing modules according to which a digital tone signal is processed. Each signal processing module includes a plurality of data groups (e.g., program, fixed data, work data). The storage has a plurality of storage areas, each assigned to a different one of the data groups. Each storage area is divided into a plurality of division areas for the plurality of signal processing modules. DSP receives address qualifying information on the difference between the size of a specified data groups (e.g., work data) for a signal processing module and the size of a specified division area which stores the specified data group. DSP sequentially executes the plurality of signal processing modules. When it has completed executing of the current signal processing module, DSP uses the address qualifying information to determine the start address of the specified division area for the next signal processing module.
