1. Pulse acquisition and processing method comprising a step of acquiring at least two pulses in at least two acquisition channels (A 1 , A 2 ,. .. , A N ) of a signal acquisition and processing device and a step of detecting the pulses acquired by at least two detection channels (V 1 , V 2 ,. . ., V N ) of the signal acquisition and processing device respectively associated with the acquisition channels, each detection channel delivering a detected pulse corresponding to an acquired pulse, the method additionally comprising: a step of distributing, in at least one available computing tile (T 1 , T 2 ,. .. , T p ), in whole or in part, in a set of computing tiles, at least one pulse detected by at least one detection channel, the detected pulse being distributed in the form of successive temporal samples in the computing tile or tiles, each temporal sample being accompanied by a time data item that identifies a start time of the temporal sample and a channel data item that identifies the acquisition channel from which the temporal sample comes, a step of storing the temporal samples in the computing tile or tiles in the set of computing tiles, a step of processing the temporal samples stored in the computing tile or tiles in order to obtain characteristic data (I) of the pulses detected, each characteristic data item (I) being associated with at least one time data item and at least one channel data item, and a step of supplementary processing of all or some of the characteristic data of the detected pulses (I) that processes said characteristic data (I) according to time data and/or channel data that are associated with the characteristic data, wherein the supplementary processing step groups together all or some of the characteristic data (I) by detection channel and/or according to time.
