There are 15 arithmetic, logical operations; it has a full shift function; it can be extended full-ahead position N-bit words. fo, f1, f2,f3 = the corresponding steady input level of F1, F2, F3, F4. QA0, QB0, QC0, QD0= the corresponding level of QA, QB, QC, QD before the establishment of steady-state input conditions. QAn, QBn, QCn= the corresponding level of QA, QB, QC at the latest time hopping.
