AN INVESTIGATION INTO THE STRUCTURE OF TRI-LATCHES AND TERNARY BASIC FLIP-FLOPS

摘要: 本文從存貯功能的數學表述出發(fā),分別就模代數和格代數等兩種情況系統地研究了三值閂鎖的各種結構。此外,根據對閂鎖輸入待存貯信號的能力要求,本文歸納了用與門,或門和二選一數據選擇器中斷反饋環(huán)路的設計技術,并在此基礎上設計了三值鎖存器。

Abstract: Starting from the mathematical expressions of storage function, this paper investigates various structures of tri-latches based on modular algebra and lattice algebra systemtically. At the request to input the signal to be stored into these tri-latches, the paper deduces some design techniques to interrupt the feedback rings with AND gate, OR gate and 1 of-2 multiplexer respectively. By the above techniques, ternary basic flip-flops can be derived further. -
