An adapter for connecting an embedded system to a control computer having a standard interface, in particular a network interface, a first subcircuit, and a second subcircuit, the first subcircuit being designed to communicate with the control computer via the standard interface by means of a standard protocol, preferably XCP. The first subcircuit is designed to convert a protocol functionality requested in the standard protocol via the standard interface, out of a set of supported protocol functionalities into the call for one or more elementary functions out of a defined overall set of elementary functions. The first subcircuit is connected to the second subcircuit via an internal interface, wherein the second subcircuit has a programmable computing module which is configured to provide at least one elementary function out of the overall set of elementary functions which can be called up via the internal interface by means of a call.

Adapter for connecting an embedded system to a control computer, and method for adapting an adapter

A method for manipulating a first function of a control program of an electronic control device, using a second function. The control program is processed using a first calculation kernel of a processor, and the second function is processed by a second calculation kernel during the processing of the control program. The first function assigns a first value to a variable and writes the first value to the storage address of the variable at a first time. The second function assigns a second value to the variable, which value is written to the storage address of the variable at a second time, wherein the second value written by the first function is overwritten. At a third time, the control program reads the second value from the storage address of the variable. A control entity coordinates the times at which the storage address of the variable is accessed.

In a method for changing a configuration of a programmable logic module, an initial configuration of the programmable logic module is read in, with a result that a logic description, in particular a mapped netlist, of the initial configuration is at least partially available. One or more logic elements and/or connection elements from the logic description of the initial configuration of the programmable logic module are replaced or reconfigured and a logic description of a target configuration having one or more additional logic elements are created, none or a plurality of elements of the initial configuration being missing in the target configuration. Assignment information is used to determine transfer points, that is to say logic elements present in the target configuration and the initial configuration, in particular registers, and/or connection elements, to which a changed logic function is applied in the target configuration, at least the logic elements of the programmable logic module which are already unused in the initial configuration being marked as free, and the additional logic elements of the target configuration being placed on the logic elements marked as free and being connected to the transfer points via unused connection elements. A changed bit stream is created from the logic description of the target configuration, and the changed bit stream is written to the programmable logic module.
