An asynchronous true four-phase handshake protocol circuit and its control method

Abstract

The present invention relates to an asynchronous true four-phase handshake protocol circuit and its control method. The circuit includes: a first inverter, a first MOS tube, a second MOS tube, a third MOS tube, a fourth MOS tube, and a fifth MOS tube , the sixth MOS transistor, the seventh MOS transistor, the eighth MOS transistor, the first inverting device and the second inverting device; the input terminal of the first inverter is connected to the first request signal; the gate of the third MOS transistor is connected to The second request signal, the gate of the fourth MOS transistor and the gate of the seventh MOS transistor are connected to the second response signal, one end of the first inverting device is connected to the first response signal; one end of the second inverting device is connected to the second request signal. The present invention only replies to the response signal when the rising edge of the request signal arrives, and captures data when the falling edge of the request signal arrives, so the present invention can reduce the overhead of the delay chain and increase the working speed of the circuit.

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
