Abstract: A plurality of characteristic modes represent traffic demand states occurring in a building in which the system is installed. When a detected traffic demand state coincides with one of the modes, operation of the system is controlled with the aid of control parameters determined thereby so that the currently detected traffic demand is processed in an optimal manner. The modes are stored and selectively read out in response to traffic demand detection. A mode creating and modifying capability accommodates new traffic demand states through a learning procedure, a mode being established by an automatic learning procedure in dependence on the results of evaluation of the traffic demand characteristic with regard to the significance, the time or period and continuity thereof. To this end, a disconnectable learning microcomputer is provided in addition to the system operation and car controlling microcomputers. Special modes can be manually input at a terminal.

Abstract: The buffer (503) has at least one intake for storage of called-up data and an address identification signal. A data search device (500) searches for the data with the addresses provided by the CPU in that stored in the buffer (503). An address calculating unit (501) determines a main memory address of the data next to be called up on the basis of the address provided by the CPU and a history of the main memory addresses for previously called-up data. An addresses prodn. device (502) produces an address of the data called up from the main memory in accordance with the calculation of the address calculating unit (501). ADVANTAGE - Improves accuracy of providing addresses in forward and backward directions.

Abstract: The data processing system has a number of processor elements (A2,A3) for processing instructions, a main memory (A4) used in common by the processor elements and a clock generator (A11) which produces a timing signal and which is connected to the processor elements. A number of parallel operation controllers (A9,A10) equal in number to the number of processor elements enables operation sync. to the timing signal. A multiprocessor operation controller (A8) connected to the processor elements enables each element to operate independently of the others. USE/ADVANTAGE - For optimal high speed parallel data processing with cache memory. VLSI design techniques used to achieve parallel operation are also effective used for multiprocessing.
