Method for generating source code

A method for configuring a control device comprising at least one arithmetic logic unit, the method comprising:

• inputting a block diagram;
• generating source code from one or more blocks of the block diagram that comprises at least two blocks and at least one signal link between the at least two blocks;
• compiling the source code for the at least one arithmetic logic unit such that executable code is generated;
• transmitting the executable code to the control device;
• and
• storing the executable code in a non-volatile memory of the control device and/or executing the executable code by the at least one arithmetic logic unit of the control device;
• wherein generating the source code comprises:
• transforming the block diagram into an intermediate representation;
• successively optimizing the intermediate representation;
• and
• translating the optimized intermediate representation into source code;
• wherein transforming the block diagram into the intermediate representation comprises transforming a block, wherein transforming the block comprises creating a reference to a block output variable, and wherein creating the reference to the block output comprises:
• detecting at least two parallel control flow branches which read or write a variable;
• identifying an operation that accesses the variable;
• checking whether a cost criterion is satisfied;
• and
• reproducing the operation in the at least two parallel control flow branches based on the cost criterion being satisfied, wherein reproducing the operation comprises shifting the operation from an original position to positions where the variable is read or written.

A non-transitory computer-readable medium having processor-executable instructions stored thereon for generating source code from one or more blocks of a block diagram that comprises at least two blocks and at least one signal link between the at least two blocks, wherein the processor-executable instructions, when executed, facilitate performance of the following:

• transforming the block diagram into an intermediate representation;
• successively optimizing the intermediate representation;
• and
• translating the optimized intermediate representation into source code;
• wherein transforming the block diagram into the intermediate representation comprises transforming a block, wherein transforming the block comprises creating a reference to a block output variable, and wherein creating the reference to the block output comprises:
• detecting at least two parallel control flow branches which read or write a variable;
• identifying an operation that accesses the variable;
• checking whether a cost criterion is satisfied;
• and
• reproducing the operation in the at least two parallel control flow branches based on the cost criterion being satisfied, wherein reproducing the operation comprises shifting the operation from an original position to positions where the variable is read or written.
