Abstract:
1. A mobile terminal apparatus comprising: a control unit to control a musical tone-generating process; a memory unit to store music content data having time management data and event data; and a hardware tone generator unit including a first-in-first-out (FIFO) memory with a predetermined capacity, a sequencer, a tone generator control register, and a tone generator, wherein said control unit reads out said music content data from said memory unit, converts the read out music content data to register write data to be written into said tone generator control register, generates tone generator control data having the converted register write data and said time management data, and stores the generated tone generator control data to said memory unit, when said control unit has available processing time, said control unit reads out a predetermined amount of tone generator control data from said memory unit and transfers the read out tone generator control data to said FIFO memory, and further reads out a following tone generator control data and transfers the read out data to said FIFO memory every time said control unit receives a data request signal from said FIFO memory, said sequencer sequentially reads out the tone generator control data having the register write data and the time management data from said FIFO memory, and then writes the register write data into said tone generator control register when timing indicated by the time management data comes, and said tone generator generates a musical tone based on the register write data written into said tone generator control register.
