摘要： PROBLEM TO BE SOLVED: To obtain a display data outputting device, which can sufficiently exhibit the writing process capability of a plotting processor, by storing display data outputted from a display picture memory that is capable of writing a new display picture or output display data outputted from a data switcher in at least one of plural display picture memories. SOLUTION: The device is provided with two plotting frame memories 1 and 2, which are capable of storing plural display data constituting of a display picture for every pixel, and two accumulating frame memories 3 and 4 which are capable of storing plural display data constituting of a display picture for every pixel. The memories 3 and 4 respectively store output display data outputted from a data switcher 13. Thus, when a plotting processor 5 writes the display data of a display picture for one plotting frame memory and outputs output display data, same display data are stored in one accumulation frame memory at the completion of the outputting.

摘要： PURPOSE:To enable overall inspection including a memory operation and parallel buses and to shorten inspection time by performing memory checks by using the same passage as real image display and data read out by an access method. CONSTITUTION:Parallel data (b) and (c) inputted to a D flip-flop 10 are fixed by the same clock signal as the fetch and use of data at a D/A conversion part, and inputted to a comparator 11 as a P input (d) and a Q input (e). The comparator 11 compares the P input (d) with the Q input (e) and when both of inputs are different, a P=Q output (f) is turned to a low level. Then, an LED is turned on by an OR circuit 12. Thus, since the data obtained by the same passage and access method as real image display are compared, the operation of the memory and the inspection including parallel buses can be checked at the same speed as real image display.
