    摘要： An address bus control system is provided of the type in which a controller including a central processing unit is connected through an address bus and a data bus to hardware modules which control equipment to be controlled. An address space defined by an address bus includes a discrimination space for discriminating the attribute of the hardware module and a function space for allocating and clearing an address space for a function interface of the hardware module. The attribute of a hardware module connected to a connector having a corresponding address is recognized using the discrimination space. The function interface of each hardware module is assigned a space within the function space in accordance with the contents of the discrimination space in concern, or the assigned space is canceled. An address of the function space can be allocated to only a necessary function interface, merely by connecting the hardware module to the connector, allowing to set up hardware modules equal to or larger than the total address space.

    摘要： A sound reproducing system that decodes audio data in a frame with which detection of a syncword fails, if a syncword included in a subsequent frame is detected, if correctness of bit stream information in the subsequent frame is proved, and if no CRC error is detected (when CRC is included). This makes it possible to solve a problem involved in a conventional system in that when a unit frame without an error check pattern is input and a synchronization detector produces a synchronization detection error signal, unpleasant sound interruption can take place even if the audio data is correct, because the correctness of the audio data cannot be checked, and hence the audio data cannot be decoded in this case.
