Abstract

The present description concerns a circuit configured to perform a multiplication between first and second values each comprising up to a number N of chunks of n bits, comprising: - a number NMUL of multiplier sub-circuits configured to generate partial products corresponding to a multiplication between one chunk of the first value and one chunk of the second value; - an adder part configured to generate an intermediate sum, corresponding to the addition of partial products of same significance, and excess bit values; - an input crossbar circuit configured to select at least one chunk of the first value and at least one chunk of the second value and to provide them to one of the multiplier sub-circuits; - a control unit configured to indicate which chunks to supply to which multiplier sub-circuit; and - a parallel adder configured to generate a value corresponding to the product.
