Communication interface for interfacing a transmission circuit with an interconnection network, and corresponding system and integrated circuit

A communication interface module to pass data between a transmission circuit and an interconnection network, comprising:

• a control circuit coupleable to the transmission circuit;
• an internal interface circuit coupleable to the interconnection network and coupled to the control circuit;
• and
• at least one memory coupled to the internal interface circuit and coupled to the control circuit, the at least one memory coupleable to the transmission circuit, wherein the communication interface is configured to:
• receive a write request from the transmission circuit, the write request arranged to direct a transmission of a predetermined amount of data;
• receive data segments from said transmission circuit;
• store said data segments in the at least one memory;
• test whether said at least one memory contains said predetermined amount of data;
• based on the test, start transmission to said interconnection network of said data stored in said at least one memory when said at least one memory contains said predetermined amount of data;
• and
• based on the test, when said at least one memory contains an amount of data less than said predetermined amount of data:
• determine a parameter to identify elapsed time since said write request is received from said transmission circuit or since a first datum is received from said transmission circuit;
• verify whether said parameter indicates that the elapsed time exceeds a time threshold;
• and
• based on the verification that said parameter indicates that the elapsed time exceeds said time threshold, start transmission of said data stored in said at least one memory.
