HIGH SPEED PARALLEL OPERATION SYSTEM FOR NUMERICAL DIFFERENTIATION AND INTEGRATION

摘要

PURPOSE:To enable high speed operation, by using a plurality of four-fundamental calculation units such as microprocessing units parallelly and calculating each row of vector calculation in the calculation of numerical differentiation and integration at the same time. CONSTITUTION:When the function is represented with the longitudinal vector in which the difference DELTAkyo of equation 1 being the Newton's interpolation formula is taken as each element, the integration equation can be expressed with equation 2. The register 2 takes the vectorelement of function to be integrated as the value, the register 1 holds the vector element of the function as the result of calculation, suitable four-fundamental calculation unit micro-CPUs 3, 4 and 5 are controlled with entirely the same program and they are connected with the register 2 with exclusive bus. Further, CPU3 is connected to the register 2 from fo, CPU4 is from DELTAfo and CPU5 is form DELTA2fo, by shifting one by one. Further, in case of numeric differentiation, it can be calculated by CPUs 3... 5. Thus, each row of the calculation of numerical differentiation and integration is calculated at the same time, to speed up the calculation.
