    • A DMA transfer technique which can be adapted to “hardware in the loop simulation” (HILS) and which requires less overhead. In a computer system having a data transfer device, a continuous DMA mechanism successively and repeatedly outputs a data transfer request in response to an enable process. A simulation system for HILS places data as a result of the simulation in a predetermined area in a memory and transfers the data from the memory to the continuous DMA mechanism together with generation ID data. The continuous DMA mechanism stores the transferred generation ID as a received ID, and receives the transferred data in response to the event that the transferred generation ID differs from the received ID being stored. The continuous DMA mechanism successively repeats the data transfer request until it is disabled.
    • 一种DMA传输技术,可以适应“循环仿真中的硬件”(HILS),并且需要更少的开销。 在具有数据传送装置的计算机系统中,连续的DMA机制响应于使能过程而连续并重复地输出数据传送请求。 用于HILS的模拟系统将数据作为在存储器中的预定区域中的模拟的结果,并将数据与生成ID数据一起从存储器传送到连续DMA机制。 连续DMA机制将传送的生成ID存储为接收到的ID,并且响应于所转移的生成ID与所接收的被存储的ID不同的事件接收传送的数据。 连续DMA机制连续重复数据传输请求,直到禁用。

    • In the speaker device, a casing and a magnetic circuit are arranged to confront each other, and a vibration body is arranged between them. The outer circumferential part of the vibration body is supported by the casing. A supporting member passes through the inside of the vibrating body and extends from the casing to the magnetic circuit. Since the supporting member for supporting the magnetic circuit passes the inside of the vibration body, it is not necessary to provide a member such as a frame for supporting the magnetic circuit from outside of the vibration body. Therefore, there is no obstacle such as a frame in a propagating direction of the sound wave generated by the vibration body, and hence the non-directivity can be ensured.
    • 在扬声器装置中,壳体和磁路布置成彼此面对,并且在它们之间布置有振动体。 振动体的外周部由壳体支撑。 支撑构件穿过振动体的内部并从壳体延伸到磁路。 由于用于支撑磁路的支撑构件通过振动体的内部,因此不需要从振动体的外部提供用于支撑磁路的框架等构件。 因此,不存在由振动体产生的声波的传播方向上的帧等障碍,因此可以确保非方向性。
