Inventor: KIKUCHI SHIGEMASA
IPC: G06F11/34
Filed: 1990-09-17
Abstract: PURPOSE:To extremely facilitate the maintenance control of a computer by storing the fault information on occurrence of faults for each substrate and therefore grasping the situation of the occurrence of faults when these faults are recovered. CONSTITUTION:An ECC circuit 5 always monitors whether a memory substrate 1 of its own has a fault or not. If a fault occurs and is identical with a 1-bit error, the circuit 5 corrects the 1-bit error and then the data stored in a memory. The circuit 5 also detects a 2-bit error. The information on these faults are reported to a memory control part 7. The part 7 stores the received fault information in a fault information store memory 6 together with the time data fetched from a bus 2. Thus the fault information can be surely stored at occurrence of the faults. As a result, the occurrence situation of faults can be grasped in detail for each substrate by reading the fault information out of the memory 6. Then the maintenance control is extremely facilitated for a computer.

Abstract: PURPOSE:To make it possible to cope with a number of targets without increasing the number of subpulses by a construction wherein transmission pulses are thinned out in accordance with velocities of the targets. CONSTITUTION:An output of each received beam formed in a beam forming circuit 3 is subjected to a frequency analysis by FET 8 and thereby a Doppler frequency (velocity information) of a target being present in each beam direction is measured. In accordance with the measured frequency, a thinned-out number for each target is calculated in a thinned-out number calculating circuit 9, while the direction of the target for each pulse after thining-out is adjusted. A required pulse number calculating circuit 10 calculates a necessary number of pulses from the thinned-out number for each beam and sends the information to a transmission timing generating circuit 11. The circuit 11 generates a transmission timing signal. While controlling a transmitter 5, this signal controls a beam steering computer 6 to which target direction information adjusted as stated above is given and controls simultaneously the timing of a data transfer between the computer 6 setting the direction of transmission of each subpulse and a phase shifter group 4. In this way, a plurality of targets are observed by one subpulse.
