![]() For high speed operation, the IC is used in conjunction with the 9342 or 93S42 carry look ahead circuit.In computer system architecture design, When operative speed requirements are not stringent, it can be used to serve in a simple ripple carry mode by connecting the Carry output (Cn+4) signal to the Carry input (Cn) of the next unit.Full Lookahead for High Speed Arithmetic Operation on Long Words.Provides all 16 Logic Operations of Two Variables Exclusive OR, Compare, AND, NAND, OR, NOR, Plus Ten other Logic Operations Arithmetic circuits are constructed using exactly the same method as we used for constructing the logic circuits.Like a 4-bit parallel adder, can be constructed by cascading four. 1. The implementation of arithmetic operations by digital circuitry is further used to. The 5th select line is used to select either one of the units. ![]() Provides 16 Arithmetic Operations Add, Subtract, Compare, Double, Plus Twelve Other Arithmetic Operations 4 selection lines are to perform the operations on two 4 bit inputs in both the units. ![]()
