DEVICE FOR CALCULATION ABSOLUTE VALUE OF THREE- DIMENSIONAL VECTOR Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: device has first register 2, first commutator 3, second register 4, second commutator 5, third register 6, third commutator 7, decoder 15. In addition device has constants memory unit 1, control unit 8, first, second and third arithmetic units 9-11, memory unit 12, sign inversion unit 13, fourth commutator 14, fifth commutator 16, device mode input 17. Introduced memory unit, constants memory unit, two commutators and control unit provides possibility to increase functional capabilities when problems having large number of coordinate conversions are solved. In particular, this provides possibility to compute directive cosines of vector which is done by one operations and the result does not need further correction. This results in possibility to increase speed of coordinate conversions, simplify control operations with device, to facilitate use and reliability of programming with insignificantly increased complexity of hardware. EFFECT: increased functional capabilities. 3 dwg
