Abstract
Methods, apparatus, systems and articles of manufacture are disclosed for anomalous memory access pattern detection for translational lookaside buffers. An example apparatus includes a communication interface to retrieve a first eviction data set from a translational lookaside buffer associated with a central processing unit; a machine learning engine to: generate an anomaly detection model based upon at least one of a second eviction data set not including an anomaly and a third eviction data set including the anomaly; and determine whether the anomaly is present in the first eviction data set based on the anomaly detection model; and an alert generator to at least one of modify a bit value or terminate memory access operations when the anomaly is determined to be present.
