A method performed by a machine learning system includes generating a set of reward values based on a set of parameter values selected by a machine learning system, each reward value of the set of reward values corresponding to a parameter value of the set of parameter values programmed at a device. The method also includes determining a reward function for maximizing a reward corresponding to a set of parameters of the device based on the set of reward values. The method further includes tuning a parameter of the set of parameters based on the reward function.

Various embodiments of methods and systems for bit flip identification for debugging and/or power management in a system on a chip ('SoC') are disclosed. Exemplary embodiments seek to identify bit flip occurrences near in time to the occurrences by checking parity values of data blocks as the data blocks are written into a memory component. In this way, bit flips occurring in association with a write transaction may be differentiated from bit flips occurring in association with a read transaction. The distinction may be useful, when taken in conjunction with various parameter levels identified at the time of a bit flip recognition, to debug a memory component or, when in a runtime environment, adjust thermal and power policies that may be contributing to bit flip occurrences.
