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

The present invention relates to a method, device and chip for transmitting pulse events. In order to improve the communication efficiency between chips / modules and reduce power consumption as much as possible, the address event expression signal is converted into a serial address event expression signal, including: Based on the protocol, the input signal is received; the received input signal is decoded to obtain the decoded signal; the decoded signal is counted and frequency-converted according to the address; the output signal is generated and output according to the frequency-converted signal. Compared with the prior art, the interface system of the present invention has multiple modes, and while reducing power consumption, it can filter some noise or too slight invalid signals, improve signal quality, and has better reliability and flexibility, and lower power consumption. cost and power consumption. The invention is suitable for the field of Internet of Things, especially for the field of brain-like chips.

Description

technical field [0001] The present invention relates to a method, a device and a chip for transmitting pulse events, in particular to a method, device and chip for transmitting pulse events during communication between brain-like 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 modules within the chip, and additional handshake lines (confirmation and request) are used to complete asynchronous communication. . In the AER protocol, events (also called pulses in the present 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, by analyzing the digital address, the front-end chip is able to send a pulse to any target neuron in the ...
