Method and device for transmitting data on asynchronous paths between domains with different clock frequencies

A device for transmitting data between a first unit, which accumulates data that are generated with a first frequency (fa), and as second unit, which requests the accumulated data with a second frequency (fs), which is smaller than the first frequency (fa), the device comprising:

• an input that is suitable to request a first total increment (v0(k)) and a first value (W(k)), which represents a time increment (t0(k)) belonging to the first total increment (v0(k)), from the first unit with the second frequency (fs), wherein the first total increment (v0(k)) is the data content of an accumulated data block provided at the requested time in the first unit;
• a filter that is configured to generate from the first total increment (v0(k)) and the first value (W(k)) a second total increment (v(k)), wherein the second total increment (v(k)) is the data content of a data block adapted to a nominal time increment (ts) of the second frequency (fs) and the second total increment (v(k)) is generated based on at least a previous first total increment (v1(k)) requested in the previous step of requesting the first total increment (v0(k)), a time increment (t1(k)) belonging to the previous first total increment (v1(k)), and a residual part (t1r(k)) of the time increment (t1(k)) belonging to the previous first total increment (v1(k)) that has not yet been processed in the previous step of generating the second total increment v(k);
• and
• an output that is configured to transmit the second total increment (v(k)) to the second unit with the second frequency (fs).
