1. A receiving device, comprising:
- a controller device for receiving a message having data;
extraction means for extracting from received data of the message a specific part thereof resulting in extracted data;
determination means for determining a plurality of processing possibilities for how the received data are to be handled, in dependence on a part of the extracted data, resulting in a handling decision, said determination means including a mask memory containing a mask for determining said part of the extracted data, said determination means further including a pointer memory coupled to said mask memory, said part of the extracted data being used to selectively address said pointer memory for determining said plurality of processing possibilities; and
taking into account the handling decision, said determination means further determining how the received data are actually to be handled by selecting a certain processing possibility from the plurality of processing possibilities.

Abstract
A description is given of a receiving device for receiving data. The receiving device extracts from the received data a specific part thereof and, depending on the content of the extracted data, decides how it must handle the received data. The receiving device described is distinguished by the fact that it determines, depending on a part of the extracted data, how the received data might have to be handled, and that, taking account of the result of this determination, it determines how the received data are actually to be handled. Such a receiving device can decide, quickly and simply with a low outlay under all circumstances, how the received data are to be handled.

15. An apparatus, comprising:
-
an input terminal for receiving data; and
a receiving device connected to said input terminal and programmed to extract from the data a specific part thereof resulting in extracted data, said receiving device further programmed to determine, in dependence on a part of the extracted data, a plurality of processing possibilities for how the data are to be handled resulting in a handling decision, said receiving device including a mask memory containing a mask for determining said part of the extracted data, said receiving device further including a pointer memory coupled to said mask memory, said part of the extracted data being used to selectively address said pointer memory for determining said plurality of processing possibilities; and
said receiving device programmed to determine by selecting a certain processing possibility from the plurality of processing possibilities how the data are actually to be handled, taking into account the handling decision.

16. A method for handling data in a receiving device, which comprises the steps of:
-
receiving a message containing data;
extracting from received data a specific part thereof resulting in extracted data;
determining, in dependence on a part of the extracted data, a plurality of processing possibilities for how the data received are to be handled resulting in a handling decision, the determining step including using a mask memory containing a mask for determining the part of the extracted data and using a pointer memory coupled to the mask memory, to receive the certain part of the extracted data and to determine the plurality of processing possibilities; and
determining by selecting a certain processing possibility from the plurality of processing possibilities how the data received are actually to be handled taking account of the handling decision.

17. A receiving device, comprising:
-
extraction means for extracting from received data a specific part thereof resulting in extracted data;
determination means for determining, in dependence on a part of the extracted data, how the received data are to be handled resulting in a handling decision and further determining, taking into account the handling decision, how the received data are actually to be handled and whether or not to receive the remainder of the received data;
said determination device including;
a plurality of message objects each having an identifier memory and an acceptance mask memory;
combinational logic coupled to the extraction means and the plurality of message objects, said combinational logic being configured to compare the extracted data to said identifier memory and said acceptance mask memory and to generate a result output based on the comparison;
a pointer mask memory coupled to the combinational logic, said pointer mask memory having a mask to define a portion of said extracted identifier used to determine how to handle the received data;
a pointer memory coupled to the pointer mask memory via said combinational logic, said pointer memory having a selection output to select at least one of said plurality of message objects to be compared with said extracted identifier; and
a comparator checking said result output.
