    • To reduce a processing load of an external CPU, when a large amount of data is initially set frequently to an image coding/decoding device. The image encoding/decoding device (data processing device) includes a first circuit and a second circuit for providing initial setting to a plurality of image processing modules (processor units), wherein the image encoding/decoding device does not receive information, which is initially set to the image processing modules, directly from the external CPU, and control information for the initial setting is set to the first circuit from the CPU. The second circuit reads in initial setting information and setting-target information of the initial setting information from outside using the control information set in the first circuit and transfers the initial setting information to the image processing module according to the read-in setting-target information.
    • 为了减少外部CPU的处理负担,当大量的数据最初被频繁地设置到图像编码/解码装置时。 图像编码/解码装置(数据处理装置)包括第一电路和第二电路,用于向多个图像处理模块(处理器单元)提供初始设置,其中图像编码/解码装置不接收最初的信息 设置为图像处理模块,直接从外部CPU,初始设置的控制信息设置为CPU的第一个电路。 第二电路使用在第一电路中设置的控制信息从外部读入初始设置信息和初始设置信息的设置目标信息,并根据读入设置目标信息将初始设置信息传送到图像处理模块 。

The CPU does not need to set the whole information, which is initially set to the image processing modules, directly to the image encoding/decoding device, and also does not need to set both a transfer source address and a transfer destination address as in DMA transfer.
    • 图像编码/解码装置包括用于向图像处理模块提供初始设置的第一电路和第二电路。 图像编码/解码装置不直接从外部CPU接收最初设置到图像处理模块的信息,并且从CPU向第一电路设置用于初始设置的控制信息。 第二电路使用在第一电路中设置的控制信息从外部读入初始设置信息和初始设置信息的设置目标信息,并根据设置目标信息将初始设置信息传送到图像处理模块。 CPU不需要将初始设置为图像处理模块的整个信息直接设置到图像编码/解码设备,也不需要像DMA那样设置传输源地址和传输目标地址 转让。
