Signed-digit arithmetic circuits using multiple-valued logic and its applications are studied. The signed-digit number in a radix r is represented by a symmetrical 2 left bracket r/2″ plus 3-valued digit set. These signed-digit arithmetic circuits are implemented by the multiple-valued current-mode circuit technology. Two applications are discussed. One is a digital filter realization using radix 4 signed-digit arithmetic circuits. The digital filter can reduce the total number of full adder chains to less than 12 percent of those for an equivalent all-binary implementation. The other is a decimal computation using radix 5 signed-digit arithmetic circuits. The decimal arithmetic circuits are effectively employed for a high-speed decimal computer.
