发明名称 AUDIO SYNTHESIZER TIME-SHARING ITS FIRST MEMORY UNIT BETWEENTWO PROCESSORS
摘要 An apparatus for processing the speech information includes a first execution device and a second execution device for executing operations at respective different execution cycles, and a first memory unit for reading and recording the speech information. The first execution device and the second execution device exploit the first memory unit in common for processing the speech information. The processing apparatus further includes a second memory unit for storage of the speech information from the first execution means or the speech information read out from the first memory unit. The first execution device records the speech information on or reads the speech information from the second memory unit during the execution cycle of the first execution device. The second execution device accesses the first memory unit during the execution cycle of the second execution device for outputting the speech information to outside. The speech information recorded in the second memory unit is read out and recorded in the first memory unit or the speech information recorded in the first memory unit is read out recorded in the second memory unit during the time of not accessing the first memory unit. The data transfer between first execution device and the second memory can be performed during the execution cycle of the first execution device, while that between the second memory unit and the first memory unit can be performed during the execution cycle of the second execution device, so that it is possible for the first execution device to perform data transfer independently, such that sound source data can be transferred at a higher speed by employing a high-speed device as the first execution device.
