Abstract
An electronic control unit (ECU) includes a central processing unit (CPU), a non-volatile memory bank, a volatile memory bank and a state machine. The state machine is in communication with the CPU and functions to selectively capture information available on an internal bus of the CPU on a cycle-by-cycle basis and store the captured information in the volatile memory, which is also coupled to the CPU.
