摘要： A display control apparatus includes a comparison control unit which performs a cyclic redundancy check over an arbitrary region of image data. The comparison control unit includes a region control unit which selects a region of the image data based on comparison region information for specifying an arbitrary region of the image displayed on the display unit as a cyclic redundancy check target region, an arithmetic processing unit which performs arithmetic processing for the cyclic redundancy check over a region selected by the region control unit, and a comparison circuit which performs error detection by comparing the result of the arithmetic processing by the arithmetic processing unit with its expected value. Error detection by the cyclic redundancy check is performed only on the target region of the cyclic redundancy check in the arbitrary region, which facilitates the cyclic redundancy check.

摘要： To enable an instrument panel to appropriately check whether or not data display is normal.A display control apparatus includes a display output control unit and a CPU. The display output control unit includes a comparison control unit which performs a cyclic redundancy check over an arbitrary region of image data. The comparison control unit includes a region control unit which selects a region of the image data based on comparison region information for specifying an arbitrary region of the image displayed on the display unit as a cyclic redundancy check target region, an arithmetic processing unit which performs arithmetic processing for the cyclic redundancy check over a region selected by the region control unit, and a comparison circuit which performs error detection by comparing the result of the arithmetic processing by the arithmetic processing unit with its expected value. Error detection by the cyclic redundancy check is performed only on the target region of the cyclic redundancy check in the arbitrary region, which facilitates the cyclic redundancy check.

摘要： A data processor including a central processing unit and a plurality of direct map cache memories (3, 4) has a plurality of area designating circuits (5, 6) for variably designating location and size of address area in the memory space managed the central processing unit and partially overlaps the address area designated by a plurality of area designating circuits. Thereby, the overlapped area (Eco) has a function as the 2-way set associative cache memory in combination with a plurality of cache memories. For the non-overlapping area, respective cache memory functions as the direct map cache memory. It is previously judged to attain the necessary data processing capability by arranging which processing routine to which address area and then executing such routine with what processing speed. Thereby, when cache object area is assigned to a plurality of cache memory, a plurality of cache memories are combined as a set associative cache for operation to the task which particularly requires high speed operation or to the data. As a result, the system can be optimized by improving the cache hit rate of the necessary area.
