Unit logik aritmetik (ALU) 32-bit direka untuk pemproses selari bit kuantum fluks tunggal (RSFQ) pantas. Dalam ALU, gerbang berjam sebahagiannya digantikan dengan gerbang tanpa jam. Ini mengurangkan bilangan D flip flop (DFF) yang diperlukan untuk pengimbangan laluan. Bilangan gerbang jam, termasuk DFF, dikurangkan sebanyak kira-kira 40 %, dan saiz rangkaian pengedaran jam dikurangkan. Bilangan peringkat saluran paip menjadi sederhana. Reka bentuk susun atur ALU dan hasil simulasi menunjukkan keberkesanan penggunaan get tanpa jam dalam litar laluan data yang luas.

Abstract: A 32-bit arithmetic logic unit (ALU) is designed for a rapid single flux quantum (RSFQ) bit-parallel processor. In the ALU, clocked gates are partially replaced by clockless gates. This reduces the number of D flip flops (DFFs) required for path balancing. The number of clocked gates, including DFFs, is reduced by approximately 40 %, and size of the clock distribution network is reduced. The number of pipeline stages becomes modest. The layout design of the ALU and simulation results show the effectiveness of using clockless gates in wide datapath circuits.
