This application discloses a processor, a program tracing method, and an electronic device, belonging to the field of chip technology. The device includes: a monitoring module for monitoring and identifying function call instructions and return instructions during program execution; a storage module for sequentially recording the addresses of function call instructions and return instructions at the time of execution through a configurable-depth buffer; and an output interface for outputting the sequentially recorded addresses to an external debugging device. The sequentially recorded addresses are used by the external debugging device to obtain and map to function names, thus obtaining the function call relationships represented by function names in the program. This results in low tracing overhead and the ability to obtain tracing results containing function call semantics.
