A Novel Ternary Controller Unit

The aim of this paper is to present a new design for a controller unit using base 3, which will be named ternary controller unit. The ternary controller unit is planned to be the future brain of the ternary central processing unit. The ternary controller unit controls the fetch and execution cycles of instructions. To achieve this task, the ternary controller unit receives instructions from the instruction register that is ternary, then a ternary decoder decodes those instructions. Finally the ternary controller unit sends the resulting control word (control signals) to other registers and logic circuits of the ternary central processing unit to determines their function at each phase of the fetch-execute cycle.
