Abstract
An automotive electronics system includes an electronic control unit and a trace adapter. The electronic control unit is configured to receive measurement signals and provide control signals. Additionally, the electronic control unit is configured to generate or provide trace signals by replacing original instructions in a binary image with trace instructions. The trace instructions are functionally equivalent, but trigger providing the trace signals. The trace adapter is coupled to the electronic control unit. The trace adapter is configured to obtain the trace signals from the electronic control unit.
Claims20
An automotive electronics system comprising:
- an electronic control unit configured to receive measurement signals, provide control signals, and to generate trace signals by replacing original instructions with trace instructions;
- and
- a trace adapter coupled to the electronic control unit and configured to obtain the trace signals from the electronic control unit.
A trace system comprising:
- a core component configured to execute a binary image;
- a main memory coupled to the core component and configured to maintain and access stored information;
- and
- a qualification component configured to replace original instructions of the binary image with trace instructions.
A method of operating an automotive electronics system, the method comprising:
- obtaining a current instruction of a binary image;
- identifying the current instruction as a traceable instruction;
- replacing the current instruction of the binary image with a trace instruction, wherein the trace instruction is functionally equivalent to the current instruction and provides trace information;
- executing the binary image;
- and
- providing trace information associated with the trace instruction.
