    • A document image processor reads data on the image of an original document and automatically sets a format for the document in a document processor such as a word processor or personal computer. First, an image scanner reads a document as image data. A character recognizer recognizes and encodes a character from the read image data, and a document processor stores the encoded document data into a document memory. When the character recognizer encodes the image data, it analyzes the structure of the document. The document processor produces format information on the basis of the result of the analysis, and sets the produced format information in the document format memory in correspondence to document data in the document memory. Thus, the document image processor reads a document image from the document, encodes the image, and sets a format for a document conforming exactly to the document image in correspondence to the encoded document data.
    • 文档图像处理器读取原始文档的图像上的数据,并且自动地将文档的格式设置在例如文字处理器或个人计算机的文档处理器中。 首先,图像扫描器将文档读取为图像数据。 字符识别器从读取的图像数据识别和编码字符,并且文档处理器将编码的文档数据存储到文档存储器中。 当字符识别器对图像数据进行编码时,分析文档的结构。 文档处理器基于分析结果生成格式信息,并将生成的格式信息与文件存储器中的文档数据相对应地设置在文档格式存储器中。 因此,文档图像处理器从文档读取文档图像,对图像进行编码,并且对应于编码的文档数据设置与文档图像完全一致的文档的格式。

    • Input/output AC characteristics of a hard macro cell is specified in advance, delay cells 15 and 16 are provided in the input and output sides of the hard macro cell, and signal propagation delay times of the delay cells 15 and 16 are set so as to satisfy the specifications. These delay times are determined in such a way that no timing error occurs at the data inputs D of the D flip-flops 11 and 22 on condition that D flip-flops 20 and 22 are arranged outside the hard macro cell 10A, the data output end Q of the D flip-flop 20 is directly connected by a line to the data input end DI of the hard macro cell 10A, the data input end of the external synchronous flip-flop 22 is directly connected to the data output end DO of the hard macro cell 10A, and a clock CLK is commonly provided to the clock input ends CK of the hard macro cell 10A and the D flip-flops 20 and 22.
    • 预先指定硬宏小区的输入/输出AC特性,在硬宏小区的输入和输出侧提供延迟单元15和16,延迟单元15和16的信号传播延迟时间被设置为 满足规格要求。 在D触发器20和22布置在硬宏小区10A的外部,数据输出的情况下,在D触发器11和22的数据输入端D处不发生定时误差的方式确定这些延迟时间 D触发器20的结束Q通过线直接连接到硬宏单元10A的数据输入端DI,外部同步触发器22的数据输入端直接连接到数据输出端DO 硬宏单元10A和时钟CLK通常提供给硬宏单元10A和D触发器20和22的时钟输入端CK。
