BACKGROUND
[0002] A device including a SoC may be subject to anomalous behaviour either from an external source or tampering with the device itself.
[0003] Anomalous activities are inherently difficult to identify as anomalous activities are sparse, unpredictable, and include any behaviour that is not typical of the device. Anomalous activities are thus difficult to quantify. Typically, this would require data to be collected and exported off chip to be examined by an individual with significant insight into the normal working behaviour of the chip and prior knowledge that an anomalous event occurred with a rough estimate of the time at which the anomalous event occurred. The collection of this data may not be possible in real world applications as this would require knowledge of ongoing anomalous behaviour (e.g., observation of the ongoing anomalous behaviour and collection of data of the ongoing anomalous behaviour). Even if such data could be obtained, this analysis remains unable to react and prevent further unexpected behaviour on the device, as the analysis is happening off chip after the event in question.
[0004] To prevent these anomalies from causing harm to a system, the anomalies are to be identified at the time of occurrence, allowing preventative measures to be taken or real-time notifications to be made.

DESCRIPTION OF EMBODIMENTS
[0025] Any methods described herein may be computer-implemented methods. The computer-implemented methods may be provided on a transitory, or non-transitory, computer-readable medium having instructions stored thereon that, when executed by a processor, cause the processor to perform the method. The processor may be a processor of a computer that also includes storage. The non-transitory computer readable medium may be store in the storage.
[0026] With reference to Figure 1 , a SoC 10 includes an integrated circuit 12, an embedded analytics monitor 14, and a diagnostics module 16.
[0027] The SoC 10 may be any of a variety of different chips for myriad different devices. The SoC 10 may be a traffic bus, for example. However, a traffic bus is described here for illustrative purposes only and should not be construed as the only type of SoC to which the present subject-matter is applicable.
[0028] The integrated circuit 12 a conventional integrated circuit where interactions between circuit components occurforthe integrated circuit to perform various operations. In the case of the SoC 10 being a traffic bus, the interactions may include read and/or write interactions.
[0029] The embedded analytics monitor 14 is independent of the integrated circuit. For example, operating the embedded analytics monitor 14 does not impact on operation of the integrated circuit 12, and vice-versa.
[0030] The embedded analytics monitor 14 monitors the interactions within the integrated circuit 12. The embedded analytics monitor 14 operates in real time. The embedded analytics monitor 14 monitors the interactions of the integrated circuit to generate analytics data by sampling data values associated with the interactions over a period of time.
[0031] The diagnostics module 16 includes a machine learning algorithm. The machine learning algorithm is trained to detect an anomaly in the analytics data indicative of a fault condition of the integrated circuit 12.
[0032] Using the illustrative example of a SoC being a data bus, the anomaly may include detecting a read operation when a write operation was expected, and vice-versa.
[0033] With reference to Figure 2, in an embodiment, the machine learning algorithm includes an autoencoder 20. The autoencoder 20 includes an encoder
22 and a decoder 24. The encoder 22 is configured to encode the analytics data
23 to a descriptor in a latent space 25. The decoder 24 is configured to decode the descriptor to generate decoded analytics data 27.
[0034] The diagnostics module (Figure 1 ) includes a data comparison module 26. The data comparison module 26 is configured to compare the decoded analytics data to the analytics data to generate a difference.
[0035] The data represented in this reduced latent space 25 is used to reconstruct the input data. Provided that the input data contained no anomalous behavior, the decoded analytics data 27 derived from the compressed representation should closely resemble the embedded analytics data 23. By introducing anomalous data, the assumption that the data may be reconstructed from the latent space is broken, as the statistical properties of the embedded analytics data 23 without anomalies are different from that which contains anomalies. This is then apparent in the distance metric between the embedded
analytics data 23 and the decoded analytics data 27 and may be detected as an anomaly.
[0036] In this way, the data comparison module 26 of the diagnostics module is configured to classify the analytics data as anomalous when a difference is above a threshold. The data comparison module 26 is also configured to classify the analytics data as non-anomalous when the difference is below the threshold. The difference may be a distance. The distance may be calculated by the data comparison module 26 of the diagnostics module using a Euclidian distance metric or using cosine similarity.
[0037] With reference to Figure 3, the machine learning model of the embodiment of Figure 2 may be trained using a computer-implemented method such that the machine learning model detects an anomaly in analytics data, generated by an embedded analytics monitor, indicative of a fault condition of an integrated circuit of a system on a chip (SoC 10). The computer-implemented method includes providing S100 a plurality of analytics data values from the embedded analytics monitor of the SoC 10. The plurality of data values are obtained by monitoring interactions within the integrated circuit 12 during normal, non-anomalous, operation. The computer-implemented method also includes encoding S102 the analytics data values to a descriptor in a latent space. The computer-implemented method also includes decoding S104 the descriptor to generate decoded analytics data. The computer-implemented method also includes determining S106 an error between the analytics data and the decoded analytics data. In addition, the computer-implemented method also includes modifying S108 the machine learning algorithm to reduce the error.
[0038] With reference to Figure 4, the invention may be captured, broadly speaking, as a computer-implemented method of detecting a fault condition of an integrated circuit of a system on a chip (SoC). The method may include generating S300 analytics data by monitoring one or more interactions within the integrated circuit 12, and detecting S302, by a machine learning algorithm, an anomaly in the analytics data indicative of a fault condition of the integrated circuit 12.
[0039] Detecting anomalies on the SoC itself using the machine learning algorithm enables real-time flagging and potentially resolution of the anomaly that would otherwise only be done offline after the SoC has finished operating. Realtime detection may be important for systems such as autonomous vehicles that are to react in real-time.

Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
