Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like figure 1 As shown, the input of the circuit of the present invention is a plurality of communication channels, and the output is a single communication channel. Each communication channel includes a data channel (the input end is Data_i, the output end is Data) and the corresponding handshake control line (the input end is ACKi, the output end is ACK), and each data channel contains a multi-bit double-rail coded data bits. The circuit mainly includes three modules: an arbitration circuit (in the dotted line box), a handshake control module and an output controller. The connection relationship is: the data bus Data_i in the external input channel is respectively connected to a validity detection circuit, and the output of the circuit is Vi; the Vi of all channels is connected to the input REQi of the tree arbitration circ...

Abstract

The invention discloses a dual-rail coding four-phase handshake protocol-based asynchronous arbiter. The arbiter comprises an arbitration module, a handshake control module and an output control module, wherein the arbitration module is used for detecting the validity of inputting dual-rail coding data and finishing arbitration among different input channels; the handshake control module is used for finishing a four-phase handshake protocol; and the output control module is used for outputting data of corresponding data channels according to arbitration results. The arbiter can be directly applied to a dual-rail coding protocol circuit and is highly modular; and each module circuit is regularized, so that the arbiter can be conveniently extended and applied to larger-scale circuits.

Description

technical field [0001] The invention relates to the field of an asynchronous arbitration circuit, in particular to an asynchronous arbitrator based on a dual-rail coded four-phase handshake protocol. Background technique [0002] Artificial neural network is a research hotspot emerging in the field of artificial intelligence in recent years. It is a complex network system composed of a large number of simple components widely interconnected by artificially imitating the behavioral characteristics and connection relationships of animal neural networks. At present, the research on artificial neural networks continues to deepen, and has been widely used in sensory signal processing fields such as pattern recognition, speech analysis and recognition, and computer vision, and has shown excellent performance. [0003] At present, VLSI technology based on silicon materials is very mature, and more and more researches use CMOS technology to design and manufacture special neural netw...
