Computational unit of a configurable integrated unit intended to improve the management of a data flow

A method implemented by a configurable integrated circuit comprising a set of computational units, each computational unit comprising:

• at least one input configured to receive incident data,
• an output,
• a core located between the at least one input and the output and configured to execute a predefined operation based on at least one input datum in order to obtain a result, and to transmit the obtained result to the output,
• a buffer memory of first in, first out type, referred to as a reception memory, associated with each input and configured to store each incident datum received by said input, the method comprises the following steps, which are implemented by each computational unit:
• detecting a validity signal received at said at least one input and triggering storage, by the reception memory associated with the input in question, of an incident datum when the detected validity signal is equal to a predefined value,
• transmitting, to the core as input datum, a datum stored in each reception memory, and trigger an execution of the predefined operation when at least one datum is stored in each reception memory of the computational unit, and when, furthermore, no execution of the predefined operation is in progress,
• transmitting, to the output, a validity signal equal to the predefined value at the same time as each obtained result is transmitted, and transmitting a validity signal different from the predefined value otherwise,
• associating an identifier with each transmitted result, the identifier associated with each transmitted result is concatenated with the transmitted result, said identifier being an identifier associated with the incident datum, said transmitted result being obtained based on the incident datum, the identifier associated with each incident datum is an identifier of a channel to which said incident datum belongs, the channel being a set of data which are used by the set of computational units to obtain the same final result based on an initial set of data, and the identifier associated with each transmitted result is the identifier of the channel to which the result belongs, wherein each computational unit of the set of computational units being interconnected according to a predefined sequence, so that, considering a first of the computational units, the output of which is connected to an input of a second of the computational units which follows the first computational unit according to the predefined sequence, the result and the validity signal transmitted by the core to the output of the first computational unit being automatically transmitted to the input of the second computational unit, and
• performing, via each aforementioned computational unit of the set of computational units, two successive executions of the predefined operation for two distinct channels without any waiting time.
