ABSTRACT:
A memory control apparatus that compresses the time widths of time slots of addresses sequentially outputted from a data processing unit so as to access a memory. Readout data is transferred to the data processing unit while expanding the time slot. In a vacant time formed by compressing the time widths of the time slots of the addresses from the data processing unit, refresh processing or hard disk transfer processing is executed. The time widths of the time slots of addresses sequentially outputted from a CPU are compressed so as to write data in the memory, and parallel to this operation, refresh processing can be executed in a vacant time. The memory control apparatus is suitably used in accesses of waveform data between a tone generator system and a waveform memory. Waveform data supplied from another unit can be written in the waveform memory parallel to tone generation using all tone generation channels of the tone generator system for tone generation.
