    • A sound data processing apparatus includes a central processing unit for controlling predetermined processing in the apparatus, a rewritable RAM, a decoder performing the decoding processing for sound data, and an interface unit for being fitted with an external memory. The sound data processing apparatus reads a driver from the external memory mounted in the interface unit and stores the read driver into the RAM, and reads the sound data from the external memory with the driver and processes the read sound data. As a result, the wastefully using of the memory capacity of the memory mounted in the sound data processing apparatus is reduced.
    • 声音数据处理装置包括用于控制装置中的预定处理的中央处理单元,可重写RAM,执行声音数据解码处理的解码器以及用于装配外部存储器的接口单元。 声音数据处理装置从安装在接口单元中的外部存储器读取驱动器,并将读取的驱动器存储到RAM中,并用驱动器从外部存储器读取声音数据,并处理读取的声音数据。 结果,减少了安装在声音数据处理装置中的存储器的存储容量的浪费。
