FIELD: automatics and computer engineering, applicable in monitoring and diagnostics systems for hardware implementation of the function of information preprocessing. SUBSTANCE: the device uses lower (1) and upper (2) tolerance limit registers, compared number register 3 with inputs 8,8and 8, respectively, which serve also as the inputs of the device, whose outputs are connected by digits to the inputs of comparison units 4 and 5; comparison unit 4 receives parallel codes of tolerance lower limit D and compared number X, and comparison unit 5 receives parallel codes of compared number X and tolerance upper limit C. The inputs of registers 1,2 and 3 serve also as the device inputs. Pulse generator 6 synchronizes the transmission of compared numbers from registers 1,2 and 3 to comparison units 4 and 5. The device compares binary numbers with upper and lower tolerance limits transmitted in a parallel code. The result of comparison is produced at device outputs 9,9and 9. EFFECT: reduced time of comparison of numbers with tolerances and expanded functional capabilities. |
