Title:
ACCESS MODULE, MEMORY MODULE, MUSICAL SOUND GENERATION SYSTEM AND DATA WRITE MODULE
Document Type and Number:
WIPO Patent Application WO/2010/010646
Kind Code:
A1
Abstract:
An access module is connected with a memory module in which musical sound data multiplexed without compression are recorded. A reading-out instruction unit transfers a reading-out instruction to the memory module in accordance with a reading-out request condition of each sound generation channel and an access condition of a nonvolatile memory module that is a subject of the reading-out, and musical sound data are read out in parallel from the memory module. Since the musical sound generation system can read out the musical sound data in parallel from a plurality of nonvolatile memory modules when reading out a plurality of the musical sound data, a sound generation delay time can be within an allowable time. Thus, a large capacity NAND flush memory, which is currently the mainstream, can be used for a musical sound data memory to achieve a high quality and small size musical sound generation system.
