ASYNCHRONOUS-LOGIC CIRCUIT FOR FULL DYNAMIC VOLTAGE CONTROL

摘要

Pre-Charge Static Logic (PCSL), is an asynchronous-logic Quasi-Delay-Insensitive architecture based on Static-Logic, featuring fully-range Dynamic Voltage Scaling including robust operation in the sub-threshold voltage regime, with simultaneous low hardware overheads, high-speed and yet low power dissipation. The invented PCSL logic circuit achieves this by integration of the Request sub-circuit into the Static-Logic cell. During the initial phase, the output of Static-Logic cell (within the PCSL logic circuit) is pre-charged. During the evaluate phase, the Static-Logic cell computes the input and the PCSL logic circuit outputs the computation.
