Asynchronous true four-phase handshake protocol circuit and control method thereof

Abstract

The invention relates to an asynchronous true four-phase handshake protocol circuit and a control method thereof. The circuit comprises a first phase inverter, a first MOS tube, a second MOS tube, a third MOS tube, a fourth MOS tube, a fifth MOS tube, a sixth MOS tube, a seventh MOS tube, an eighth MOS tube, a first phase inverting device and a second phase inverting device. The input end of the first phase inverter is connected with a first request signal; the grid electrode of the third MOS tube is connected with a second request signal, the grid electrode of the fourth MOS tube and the grid electrode of the seventh MOS tube are both connected with a second response signal, and one end of the first inverting device is connected with a first response signal; one end of the second inverting device is connected with a second request signal. Only the response signal is replied when the rising edge of the request signal arrives, and the data is captured when the falling edge of the request signal arrives, so that the overhead of a delay chain can be reduced, and the working speed of the circuit is improved.

Description

technical field [0001] The invention relates to the field of electronic product design, in particular to an asynchronous true four-phase handshake protocol circuit and a control method thereof. Background technique [0002] In applications such as wearable electronics, medical electronics, and wireless sensor nodes, it is necessary to reduce the power consumption of the system for better battery life. Asynchronous circuits do not need clock drive and only work when data arrives, so they can effectively reduce the power consumption of the system. System power consumption. [0003] Common bundled data asynchronous circuit structures such as figure 1 As shown, to ensure that the flip-flop can capture data correctly, the delay chain delay must be greater than the data path delay. In the traditional four-phase handshake protocol circuit, the controller captures data when it receives the rising edge of the request signal from the previous stage, so the delay of the rising edge o...

Problems solved by technology

In the traditional four-phase handshake protocol circuit, the controller captures data when it receives the rising edge of the request signal from the previous stage, so the delay of the rising edge of the delay chain transmission request signal needs to be greater than the delay of the data path

The delay of the falling edge of the delay chain transmission not only cannot be used for delay matching of the data path, but also limits the working speed of the circuit
