Abstract
A system for acquiring information on the operation of an electronic control unit (ECU) includes a controller and a non-volatile memory. The controller is coupled to address and data buses of a central processing unit (CPU), which is located within an electronic control unit (ECU). The controller includes a register and/or a logging buffer for facilitating ECU analysis. The non-volatile memory is located within the ECU and is coupled to the address and data buses of the CPU. The register logs the current memory address of the non-volatile memory, when the controller determines the current memory address is a memory address of interest. The logging buffer logs the current memory address of the non-volatile memory each time the controller determines the current memory address is a memory address of interest.
