MODULAR RECONSTRUCTED ARIPHMETIC AND LOGICAL UNIT WITH SEPARATE FIRMWARE CONTROL OF COMPUTER SECTIONS AND SIMULTANEOUS MAINTENANCE OF SEVERAL INSTRUCTION STREAMS

The work is concerned with the procedures of calculation organization in the ariphmetic and logical units of the microprocessors. The aim is to develop the principles for construction of the modular reconstructed ariphmetic and logical unit with increased efficiency of using computer resource. The method for synthesis of the modular reconstructed ariphmetic and logical unit, 12 procedures for union of the computer sections in reconstructed ariphmetic and logical unit and also three criteria of the computer section stealing have been proposed. The efficiency of using computer resource in ALU of the microprocessors 80286/80287 of firm "Intel" has been increased; the procedures for union of the computer sections in reconstructed ALU provide the microprocessor power increase; the software "Object-oriented simulation system" and "Object-oriented data base" have developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
