A data processing system and a method for detecting an anomaly in the data processing system are provided. The method includes receiving a plurality of program counter values from a processing core of the data processing system. Each of the plurality of program counter values corresponds to an instruction being executed in the data processing system. A histogram is constructed using the plurality of program counter values. The histogram is provided to a machine learning (ML) model and used for training the ML model. If training has already been accomplished, the histogram is provided during inference operation of the ML model. The ML model and the histogram are used to detect an anomaly in the data processing system. If an anomaly is detected, an indication of the anomaly may be provided.
