Title:
PROCESSOR FOR CALCULATING INTERACTION FORCE FOR GRAVITY MULTIPLE SYSTEM AND ELECTRIC FORCE MULTIPLE SYSTEM
Document Type and Number:
Japanese Patent JP2948378
Kind Code:
B2
Abstract:
PURPOSE: To provide an inexpensive processor which can calculate interactive force and potential in a gravity or electric force multiple system at a speed of the same order as a supercomputer.
CONSTITUTION: A relative position calculation means 2 obtains the coordinate differences of X, Y and Z based on the coordinates of two points, and converts them to logarithm expression. A relative distance calculation means 3 obtains the square of a relative distance r2 from the coordinate difference and the prescribed constant, and a 1/2 power-raising means 4 and a 3/2 power-raising means 5 obtain (r) and r3. Mass or a change Mj is supplied from the external part of an integrated circuit 1 at every cycle. Logarithm expression division means 6a and 6b obtain Mj/r3 and Mj/r. Interactive force calculation means 7a-7c calculate the products of Mj/r3 and the respective coordinate differences. A potential calculation means 8 calculates u*(Mj/r). Fixed point conversion means 9a-9d convert logarithm expression into fixed point expression. Values converted into fixed point expression in addition means for integration 10a-10d are sequentially integrated in integrated value register means 11a-11d. A processing in the integrated circuit 1 is made into a pipe line.
