    摘要: 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.

    摘要: 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.
