Abstract (en)

[origin: WO2022129156A1] Computing circuit for computing a weighted sum of a set of first data by way of at least one parsimony management circuit comprising a first buffer memory for storing all or some of the first data (MEM_A) delivered sequentially (SEQ1) and a second buffer memory for storing all or some of the second data (MEM_B) delivered sequentially (SEQ2). The parsimony management circuit (CGF) furthermore comprises a first processing circuit (CT_A) able: to analyse the first data in order to look for the first nonzero data (MNULL1- MNULL4) and define a first jump indicator (isl) indicating a jump between two successive nonzero data, and to command the transfer, to the distribution circuit (DIST), of a first datum (Xi) read from the first data buffer memory based on said first jump indicator. The parsimony management circuit (CGF) furthermore comprises a second processing circuit (CT_B) able to command the transfer, to the distribution circuit (DIST), of a second datum (Wi) read from the second data buffer memory based on said first jump indicator.
