Abstract
In a method and apparatus for acquiring a derived data value from among individual data values generated by a multiplicity of data units which are serially connected in a fixed order, each data unit to which a preceding data unit is assigned receives a data value from the preceding data unit, logically links it to a locally generated individual data value and passes on the resulting data value, so that the data value which is passed on by the last data unit represents the derived data value. The passing on of data values is carried out bit by bit in serial fashion, each data unit linking a received bit to the corresponding bit of its own individual data value, and passing it on before it receives a further bit of the data value.
Claims21
A method for acquiring a derived data value from individual data values generated respectively by a multiplicity of data units which are serially connected in a defined sequence, each data unit to which a preceding data unit is assigned receiving a data value from said preceding data unit, linking it to an individual data value which is generated by said data unit itself, and passing on a data value resulting from such linking, whereby a data value which is passed on by the last data unit in said defined sequence represents the derived data value;
- wherein:
- each respective data unit receives data values serially in the form of successive sections;
- each said respective data unit links a received section with a corresponding section of data which is generated by said respective data unit;
- and
- said respective data unit passes on a result of said linking before it links a further received section of ad received data value.
A device for acquiring a derived data value from individual data values generated respectively by a multiplicity of data units which are serially connected via a data line in a defined sequence for the transmission of the data values, each data unit which receives a data value via the data line linking the received data value to an individual data value which it generates itself, and passing on a resulting data value obtained in this manner, via the data line;
- whereby a data value passed on by the last data unit represents the derived data value;
- wherein
- each respective data unit passes on its data value serially in the form of successive sections;
- and
- each data unit which receives a section of a data value links said section to a corresponding section of its own individual data value, and passes it on before it receives a further section of the data value.
A method for addressing a data unit contained in a multiplicity of data units which are serially connected in a defined order;
- said method comprising:
- each data unit to which a preceding data unit is assigned receiving an address value from said preceding data unit;
- each data unit comparing the received address value with a predefined value which is identical for all of the data units;
- when the received address value corresponds with the predefined value, the data unit is addressed;
- and
- at least when the received address value does not correspond with the predefined value, the data unit changes the address value according to a predefined operation and passes on the resulting address value obtained in this manner.
A method for acquiring an individual data value generated by a particular addressed data unit, from among a plurality of individual data values which are generated at a multiplicity of data units which are serially connected in a defined;
- said method comprising:
- each data unit to which a preceding data unit is assigned receiving an address value from said preceding data unit;
- each data unit comparing the received address value with a predefined value which is identical for all of the data units;
- when the received address value corresponds with the predefined value, the data unit is addressed;
- at least when the received address value does not correspond with the predefined value, the data unit changes the address value according to a predefined operation and passes on the resulting address value obtained in this manner;
- and
- the addressed data unit transmitting a data value which is passed on via any data units which follow the addressed data unit.
