Abstract

A method and a device having a processor module for controlling operating sequences, in particular in an engine control unit in a motor vehicle, peripheral elements being selected by a processor module having a predetermined number of select interfaces by select signal output over these select interfaces, and instructions being transmitted to the peripheral elements over at least one information interface of the processor module. Selection identifiers are assigned to the instructions and transmitted together with them. Thus, a selection of peripheral elements is made by a select signal and a selection identifier.

Claims

1. A method for controlling an operating sequence, comprising the steps of:

causing a processor module including a predetermined number of select interfaces to select a peripheral element in accordance with a select signal output over one of the select interfaces;

transmitting an instruction to the peripheral element over at least one information interface of the processor module;

assigning a selection identifier to the instruction; and

transmitting the selection identifier together with the instruction, wherein;

a selection of the select peripheral element is made by the select signal and the selection identifier.

2. The method according to claim 1, wherein:

the operating sequence is for an engine control unit in a motor vehicle.

3. The method according to claim 1, wherein:

the selection identifier and the instruction are transmitted in digital form as an entity including individual binary signals, and

the selection identifier replaces a portion of individual signals of the instruction so that, when transmitted as the entity, the selection identifier and the instruction again have the same predetermined number of individual signals.

4. The method according to claim 1, wherein:

the selection identifier and the instruction are transmitted in digital form as an entity including individual binary signals,

the instruction includes a predetermined number of individual signals, and

the selection identifier supplements the instruction so that a number of individual signals in the selection identifier and the instruction, when transmitted as the entity, is greater than the predetermined number of individual signals.

5. A device for controlling an operating sequence, comprising:

a processor module including a predetermined number of select interfaces;

an information interface;

a plurality of peripheral elements connected to the processor module via the information interface and via the predetermined number of select interfaces, wherein;

the peripheral elements are selected by the processor module on the basis of select signals output over the select interfaces, and

instructions are transmitted to the selected peripheral elements over the information interface;

a first arrangement for assigning selection identifiers to the instructions; and

a second arrangement for selecting one of the peripheral elements on the basis of one of the select signals and one of the selection identifiers.

6. The device according to claim 5, wherein:

the operating sequence is for an engine control unit in a motor vehicle.

7. The device according to claim 5, wherein:

at least two of the peripheral elements can be connected to one of the select interfaces of the processor module, the at least two of the peripheral elements being different from one another.

8. A processor module for controlling an operating sequence, comprising:

an information interface;

a predetermined number of select interfaces;

an arrangement for outputting select signals over the select interfaces;

an arrangement for outputting instructions over the information interface, wherein;

peripheral elements are selected by the select signals output over the select interfaces, and

respective ones of the instructions are transmitted over the information interface to the selected peripheral elements; and

an arrangement for assigning selection identifiers to the instructions, respective ones of the peripheral elements are selected on the basis of the selection identifiers and the select signals.

9. The device according to claim 8, wherein:

the operating sequence is for an engine control unit in a motor vehicle.
