METHOD AND DEVICE FOR TRANSMITTING DATA ON ASYNCHRONOUS PATHS BETWEEN DOMAINS WITH DIFFERENT CLOCK FREQUENCIES

摘要

The invention relates to a method for transmitting data between a first unit which accumulates data that has been generated with a first frequency and a second unit which requests the accumulated data with a second frequency. The method has the steps of requesting a first total increment and a first value, which represents a time increment belonging to the first total increment, from the first unit, said first total increment being the data content of the accumulated data block provided at the request time in the first unit; generating a second total increment from the first total increment using the first value, the second total increment being the data content of a data block adapted to a nominal time increment of the second frequency; and transmitting the second total increment to the second unit.

1. A method for transmitting data between a first unit which accumulates data that has been generated with a first frequency (fa) and a second unit which requests the accumulated data with a second frequency (fs), which is smaller than the first frequency (fa), the method comprising:
requesting 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, wherein the first total increment (v0(k)) is the data content of the accumulated data block provided at the requested time (k) in the first unit, generating of a second total increment (v(k)) from the first total increment (v0(k)) using the first value (W(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 transmitting the second total increment (v(k)) to the second unit.
