Title: Control system of memory copy
Inventor: IKUTA AKIRA
IPC: G06F12/16
Filed: 1980-11-12
Abstract: PURPOSE:To prevent the lowering of the overall processing capacity of a common controller, by executing autonomously memory copying action through the common memory controller just by a command from a processor and meanwhile carrying out a process independent of the copying action through the processor. CONSTITUTION:When a common memory controller 2-0 and 2-1 receive a command indicating to copy a part of the storage data of a common memory 3-0 to a common memory 3-1 from a processor CP1, the controller 2-0 fetches the addresses at and after a tip address 18-0 in a memory region 17-0 where the data to be copied is stored. While the controller 2-1 receives the data via a control circuit 5-0. Then whether or not a request for the operations excepting a main copying action is given to the controllers 2-0 and 2-1 from the processor CP1 is confirmed every time the copying action is through with a word. When no request exists, the main copying action is continued. Then a reading or writing action, if carried out, is interlaid between the main copying action.

Title: Moire prevention system
Inventor: EJIRI KOUICHI
IPC: H04N1/40
Filed: 1981-10-06
Abstract: PURPOSE:To vary the probability of dot appearance of every color at random, and to prevent moire by comparing a threshold value which varies irregularly with time with the density or luminance level of a picture element, and inhibiting the plotting of a picture element which has a level lower than the threshold value. CONSTITUTION:A read picture-element signal is inputted to the comparator 108 of a moire preventing circuit. The comparator 108 inputs a threshold value read out of a threshold level memory 109 as well to compare it with the level of the picture-element signal. When the level of the picture-element signal exceeds the threshold value, the output of the comparator 108 goes up to 1 and a driver 106 turns on a light source 104 to plot the picture element. On the other hand, when the output is 0, the plotting of the picture element is inhibited. Then, a pulse from a random generator 112 is also inputted to a counter 110, so the readout order of the threshold value varies with time. Therefore, the probability of dot appearance of each color varies at random to prevent the generation of moire.
