Abstract:
PROBLEM TO BE SOLVED: To shorten the processing time of conversion from a plurality of bit lengths, allocated to a plurality of character strings, respectively, to a plurality of codes. SOLUTION: A Huffman table decoding circuit stores a bit length bl[N] assigned to each character on input of the bit length assigned to the character, and stores the order of respective character strings among character strings to which the same bit length is assigned in code_fin[N]. Further, the number of characters to which the same bit length is assigned is stored in bl_count[M], and on the basis of the storage, a minimum code having the same bit length is stored in code_min[M]. Consequently, a selector 31 extracts the minimum code specified with bl[N] among a plurality of minimum standards stored in the code_min[N], and an adding circuit 32 performs processing for adding the minimum code to the value stored in code_fin[N] in parallel, and defines the added results as a code assigned to the character.

Abstract:
PROBLEM TO BE SOLVED: To provide a method or the like capable of shortening the execution time and starting time of a test more when a multi-processor system performs a test of a main memory more than when one processor performs the test. SOLUTION: The method for testing a main memory (MM) by a multi-processor system (MPS) provided with a main processor (MP) and a plurality of sub-processors (SP) having a DMA transfer mechanism and a local store (LS) is provided, which has the steps: in which the MP allocates a partial memory area (PMA) of the MM to each SP; for requesting each SP for a test of a PMA; in each SP files data in its LS in response to the request; in which each SP performs DMA transfer of data of the LS to a PMA; in which each SP performs DMA transfer of the data of the PMA to the LS; in which each SP tests the LS; and the MP integrates test results in response to each test completion to determine the test results of the MM.

PROBLEM TO BE SOLVED: To provide an information processor, for which it is not necessary to analyze the number of stages of FIFO from the character of data for improving performance, by dynamically having the number of stages of FIFO optimal at that time. SOLUTION: This device is provided with a data FIFO 22 for storing data sets and a next pointer 29 having storage areas as many as in this data FIFO. The preceding data set is stored in a storage area '1' of the data FIFO 22 and the following data set is stored in a storage area '7' of the data FIFO 22. At this time, '7' is stored in the storage area '1' of the next pointer 29 as storage area information of following data. On the basis of this storage area information '7', the following data set is read out of the storage area '7' of the data FIFO 22.

PURPOSE: To display a halftone without generating any flicker or moving phenomenon. CONSTITUTION: In a unit area 32 of a 1st frame F3n of LCD, picture elements containing the colors (surrounded by circles) of different lightness in the order of RGB in column direction are displayed in the order of RGB in row direction and in the unit area 32 of 2nd and 3rd frames F3n+1 and F3n+2 , the picture elements are displayed according to this order in the row and column directions as well. Concerning the respective picture elements in the unit area 32, the pictures containing the colors of different lightness in the order of RGB are displayed in the order of the 1st, 2nd and 3rd frames F3n , F3n+1 and F3n+2 . Thus, the lightness of only one of three colors RGB is changed for each picture element, the lightness is equally changed inside the unit area, the respective colors are distributed to the different positions of respective frames, and the colors of different lightness are equally arranged without concentrating the picture elements of different lightness into one frame.

PURPOSE: To plot the straight line and circular arc of a width at a high speed on a graphic display. CONSTITUTION: For both of a point for which only an X coordinate is increased by one from a present point and the point for which only a Y coordinate is increased by one, whether or not they are present between contour lines f1 and f2 for stipulating the line of width 1 is judged. When the point for which only the X coordinate is increased by one is present between the contour lines f1 and f2, the point is plotted and selected as the next pixel. When it is not so and the point for which only the Y coordinate is increased by one is present between the contour lines f1 and f2, the point is plotted and selected as the next pixel. When neither of them is present between the contour lines f1 and f2, the point for which both X coordinate and Y coordinate are increased by one is plotted and selected as the next pixel.
