Title: Producing system for hamming check bit
Inventor: UCHIDA NOBUO
IPC: G06F11/10
Filed: 1985-09-06
Abstract: PURPOSE:To shorten the processing cycle and to relieve the delaying time for the production of a hamming check bit (HCB), by performing the production of the HCB to one data element on a time-division basis. CONSTITUTION:A hamming check code (HCC) is constituted in such a way that when the HCC is divided to the unit of byte, for example, a cyclic pattern can be formed and HCB producing circuits are provided correspondingly to the byte-unit patterns and, also by dividing the circuits into the unit of HCB. By cascade-connecting the output of each HCB producing circuit for reinputting the output to the next HCB producing circuit, the production of the HCB to one data element is performed on a time-division basis. Therefore, by providing HCB producing circuits C0-C7 to the B0 (8 bits) data of the output of an operator only, the processing cycle can be shortened and the delaying time to the production of the HCB can be relieved, since the production of the HCb is completed at the moment when arithmetic results to all data (64 bits) are obtained.

Filed: 1985-09-09
Abstract: PURPOSE:To improve both working speed and locus accuracy of a robot arm by storing the speed of each arm calculated in the first working operation in case the robot repeats the same action. CONSTITUTION:When a robot is first played back, the position data on the working locus of each arm is extracted out of a position storing means 21. Then the moving speed of each arm is calculated by a moving speed arithmetic means 23 and stored in a moving speed storing means 22 and also sent to a data selecting means 24. Thus a drive means 25 for objects to be driven is actuated. While the data on the moving speed of each arm obtained in the first play-back mode and stored in the means 22 is supplied to the means 25 via the means 24 in the second and subsequent play-back modes of the robot. In such a way, the time needed for calculation of the moving speed of each arm is shortened. This increases the working speed of the robot.
