Embedded cyclical redundancy check values

A device for generating a data packet to be transmitted comprising data and at least one value for a cyclic redundancy check (CRC) value, the CRC value being generated using at least one previously determined polynomial based on at least some of the data, the device comprising:

• an initializer to initialize a counter value;
• a counter to count units of data, the counter being adapted to change a counter value based on the counted units of data;
• a generator to generate a CRC value over the counted units of data since the counter value last reached the reference value or the counter value was initialized;
• and
• an adder to add the CRC value into the data packet.

A method for checking a received data packet comprising data and at least one value for a cyclic redundancy check (CRC) value, a first CRC value being generated using at least one previously determined polynomial on the basis of at least a first part of the data, a second CRC value being generated using the previously determined polynomial based on at least a second part of the data, the method comprising:

• initializing a counter value;
• counting units of the first part of data from the received data packet, a counter value changing for each unit of data;
• detecting the first CRC value in the data when the counter value reaches a reference value;
• detecting the second CRC value in the data when all the units of data in the data packet have already been counted;
• and
• checking the detected CRC values.
