    • According to one embodiment, a semiconductor device includes a processor, and a memory device. The memory device has a nonvolatile semiconductor storage device and is configured to serve as a main memory for the processor. When the processor executes a plurality of programs, the processor manages pieces of information required to execute the programs as worksets for the respective programs, and creates tables, which hold relationships between pieces of information required for the respective worksets and addresses of the pieces of information in the memory device, for the respective worksets. The processor accesses to the memory device with reference to the corresponding tables for the respective worksets.
    • 根据一个实施例,半导体器件包括处理器和存储器件。 存储器件具有非易失性半导体存储器件,并且被配置为用作处理器的主存储器。 当处理器执行多个程序时,处理器管理作为各个程序的工作流程执行程序所需的信息,并创建表,其保持各工作组所需的信息和各条信息的地址之间的关系 在存储器件中,用于各个工作台。 处理器参考相应工作台的相应表访问存储器件。

    • A parallel computer of this invention includes a plurality of memory elements and a plurality of processing elements and each of the processing elements is connected to logically adjacent memory elements. For example, the processing element which corresponds to a logical position (i, j) is connected to the memory elements which correspond to a plurality of logical positions (i, j), (i, j+1), (i+1, j) and (i+1, j+1). It is preferable if each of the memory elements can be accessed from the exterior. According to this invention, efficient memory access can be made and the parallel processing can be performed at high speed without increasing the hardware amount and making the control operation complicated. Further, the operation speed of the image processing can be enhanced by constructing an image memory by use of a plurality of memory elements and causing the processing element to effect the image processing in a distributed and cooperative manner.
    • 本发明的并行计算机包括多个存储器元件和多个处理元件,并且每个处理元件连接到逻辑上相邻的存储元件。 例如,对应于逻辑位置(i,j)的处理元件连接到与多个逻辑位置(i,j),(i,j + 1),(i + 1, j)和(i + 1,j + 1)。 优选地,可以从外部访问每个存储元件。 根据本发明,可以进行有效的存储器访问,并且可以高速执行并行处理,而不增加硬件量并使控制操作变得复杂。 此外,可以通过使用多个存储元件构造图像存储器并且使处理元件以分布和协作的方式实现图像处理,来增强图像处理的操作速度。

    • An image processing portion for conducting the specified processing of an image to be reproduced by an image forming portion based on the processed image data is constructed as a single control portion. Consequently, the development of a variety of digital copying machines requires preparation of specially designated control boards according to levels of the products. This makes machines expensive and requires users to pay a considerable initial cost. An image processing device of the present invention is provided with an image information inputting means for inputting image information as a first level image, a main image-processing board for conducting the specified processing of the input image information of the first revel image, a sub image-processing board for conducting the specified processing of the image information processed by the main image processing board and outputting the information as a second level image, and a means for reproducing an image according to the image information processed by the main image-processing board or the sub image-processing board. These boards are independent from each other in the circuit configuration.
    • 构成作为单个控制部分的图像处理部分,用于基于经处理的图像数据对由图像形成部分再现的图像进行特定处理。 因此,开发各种数字复印机需要根据产品的级别准备专门指定的控制板。 这使得机器昂贵,并且要求用户支付相当大的初始成本。 本发明的图像处理装置设置有用于输入作为第一级图像的图像信息的图像信息输入装置,用于对第一图像的输入图像信息进行指定处理的主图像处理板,子图像 图像处理板,用于对由主图像处理板处理的图像信息进行指定的处理并输出作为第二级图像的信息;以及用于根据由主图像处理板处理的图像信息再现图像的装置 或子图像处理板。 这些电路板在电路配置中彼此独立。
