Abstract
According to an embodiment, a sensor including a machine learning core (MLC) and a finite state machine (FSM) circuit for detecting a shock event is provided. The MLC continuously calculates a value based on the change in velocity. The FSM circuit compares the value to a first threshold and generates a first interrupt if it is greater than the first threshold. The FSM circuit then compares the value to a second threshold less than the first threshold and generates a second interrupt if it is less than or equal to the second threshold after the first interrupt. The MLC calculates a maximum value between the first and second interrupts and stores it in a register, which is read by an application processor of a host device after receiving the second interrupt. The maximum acceleration norm value is reset after a delay after the second interrupt is generated.
