Problems solved by technology

At the same time, the realization of ultra-low power consumption of brain-like chips is the unanimous pursuit of engineers. The existing processing chips need to consume a lot of power to access the memory after receiving the input pulse signal, and even some noise will wake up the processing chips to work.

Abstract

In order to improve the communication efficiency between chips/modules and reduce the power consumption as much as possible, the invention converts an address event expression signal into a serial address event expression signal, and comprises the following steps: receiving an input signal based on a protocol; decoding the received input signal to obtain a decoded signal; carrying out counting and frequency conversion on the decoding signals according to addresses; and generating and outputting an output signal according to the frequency-converted signal. Compared with the prior art, the interface system provided by the invention has multiple modes, can filter some noise or too slight invalid signals and improve signal quality while reducing power consumption, and has better reliability and flexibility and lower cost and power consumption. The method is suitable for the field of Internet of Things, and is especially suitable for the field of brain-like chips.

Description

technical field [0001] The present invention relates to a method, device and chip for transmitting pulse events, in particular to a method, device and chip for transmitting pulse events during communication between brain-inspired chips or modules. Background technique [0002] Address Event Representation (AER) is used for communication between neuromorphic chips (also known as brain-like chips or neuromorphic chips) or between internal modules of the chip, and additional handshake lines (confirmation and request) are used to complete asynchronous communication . In the AER protocol, events (also called pulses in this invention) are transmitted through a high-speed digital parallel bus. When the front-end chip or sensor generates an output pulse, the AER encoder assigns a digital address to the pulse, and the information is routed through the bus. to the target chip, and by analyzing the digital address, the front-end chip is able to send a pulse to any target neuron in the...
