    • A bus arbitration apparatus for an image processing processor is operable such that when a channel having a high necessity of a real-time processing operation issues a bus use request, a bus use permission is not given to another channel having a low necessity of a real-time processing operation. The bus arbitrator of the data includes a timer for counting down use permission time with respect to the channel having the high necessity of the real-time processing operation, and a register for the channel having the low necessity of the real-time processing operation. A value larger than a maximum value of the timer is set to the value of the register. In the bus arbitration, the value of the register is compared with that of the timer, and then the bus use permission is given to a channel having the small value.
    • 用于图像处理处理器的总线仲裁装置是可操作的,使得当具有高实时处理操作的必要性的信道发布总线使用请求时,总线使用许可不被给予具有低真实性的另一信道 时间处理操作。 数据的总线仲裁器包括:相对于具有高实时处理操作的必要性的信道的下降使用许可时间的计时器,以及用于实时处理操作的必要性低的信道的寄存器。 大于定时器最大值的值被设置为寄存器的值。 在总线仲裁中,将寄存器的值与定时器的值进行比较,然后将总线使用许可赋予具有较小值的通道。
