“…The core of the asynchronous circuit is the asynchronous controller. The paradigm of asynchronous controller has three: Celement [3,4], Click [5] and GasP [6,7,8,9]. Compared with Celement and Click, GasP controllers are perfectly used in high-speed asynchronous circuits by careful selection of transistor size [8].…”

The GasP circuit is a high-speed controller that has been used more often in the field of asynchronous circuits. However, in the conventional GasP design method, the matching process of its internal delay lacks the consideration of the circuit application environment. In view of this, this paper proposes three delay adjustment methods by combining the usage scenario of the circuit and the logical effort. The method first adjusts the pulse width of the digital circuit, the ability to drive the DFF and the maximum equivalent frequency of the circuit, then customizes the delay and drive of the GasP, and finally verifies the performance with a NoC built with the GasP. The experimental results show that the maximum equivalent frequency of GasP can reach 2.28GHz in 110nm CMOS process, which is about 10 times of the classical synchronous design.
