System-on-chip and method for performing a diagnosis during runtime

A system, comprising

• a printed circuit board (PCB);
• and
• a first semi-conductor chip mounted on the PCB,
• wherein the first semi-conductor chip includes:
• a plurality of functional circuitries, which communicates with each other via a system bus, wherein the plurality of functional circuitries include one or more neural processing units (NPUs) configured to perform operations for an artificial neural network (ANN) model;
• and
• a diagnosing circuitry electrically connected to the plurality of functional circuitries and configured to analyze a state of at least one functional circuit among the plurality of the functional circuitries,
• wherein the semi-conductor chip is configured to deactivate at least one NPU by isolating the at least one NPU, replacing an output signal of the at least one NPU with a predetermined signal and revoking an address of the at least one deactivated NPU.

A method for diagnosing a system on chip (SoC) during runtime, the method comprising:

• communicating, via a system bus of the SoC, a plurality of functional circuitries in the SoC to communicate with each other;
• wherein the plurality of functional circuitries include one or more neural processing units (NPUs) configured to perform operations for an artificial neural network (ANN) model;
• analyzing a state of at least one functional circuit among the plurality of the functional circuitries;
• and
• deactivating at least one NPU by isolating the at least one NPU, replacing an output signal of the at least one NPU with a predetermined signal and revoking an address of the at least one deactivated NPU.
