DEVICE FOR FORMING OVERFLOW SIGNAL Russian patent published in 1994 - IPC

FIELD: computer technology. SUBSTANCE: device has AND gate, the first mask former and group of modules for forming overflow signal with corresponding couplings. The second mask former, null decoder and new couplings are brought into the device additionally. Module for forming overflow signal has a new structure. Higher speed of operation is achieved due to providing parallelism of null decoding for required number of groups of digits and inspection of overflow in single required group of digits of information input of the device. EFFECT: improved speed of operation. 2 cl, 4 dwg
