Abstract: An example method comprises receiving a number of inputs to a system employing an artificial neural network (ANN), wherein the ANN comprises a number of ANN partitions each having respective weight matrix data and bias data corresponding thereto stored in a memory. The method includes: determining an ANN partition to which the number of inputs correspond, reading, from the memory the weight matrix data and bias data corresponding to the determined ANN partition, and a first cryptographic code corresponding to the determined ANN partition; generating, using the weight matrix data and bias data read from the memory, a second cryptographic code corresponding to the determined ANN partition; determining whether the first cryptographic code and the second cryptographic code match; and responsive to determining a mismatch between the first cryptographic code and the second cryptographic code, issuing an indication of the mismatch to a controller of the system.

Abstract: Apparatuses and methods for power regulation based on input power using circuitry are disclosed herein. An example apparatus may include a reference circuit configured to receive a first voltage and a second voltage and to provide an output reference voltage at an output node having a value equal to the second voltage subtracted from the first voltage. The reference circuit may be configured to mirror a current of a first circuit coupled between the second voltage and a reference voltage through a second circuit coupled between the first voltage and the output node. The example apparatus may further include a power circuit configured to provide a third voltage based on the output reference voltage. The third voltage may have a value that is equal to the output reference voltage.
