Abstract: The invention is generally directed to systems and methods of monitoring or predicting a service event for an industrial asset using an artificial intelligence of things (AIoT) system including an AIoT device, AIoT cloud, and a self-learning AI classification and analytics engine. The device may include one or more sensors and an inference engine for reducing power consumption and detecting anomalies at the edge and sending data associated with anomalies to a signal processor for classification and AI-driven automatic configuration. Classification may be based on narrow-band analysis and/or machine learning models. If an anomaly is detected power may be provided to a communication module to send sensor data to the signal processor for classification and/or further processing. Classifications or determinations made by the signal processor or detected through a work-order system may be used to automatically retrain the inference model on the edge, so that the system is self-learning.

Abstract: A method and system to indicate which page within a software-managed page table triggers an exception within a microprocessor, such as, for example, a digital signal processor, wherein a software-managed translation lookaside buffer (TLB) module receives a virtual address produced by an instruction within a Very Long Instruction Word (VLIW) packet, such as, for example, a fetch instruction, and further compares the virtual address to each stored TLB entry. If a match exists, then the TLB module outputs a corresponding mapped physical address for the instruction. Otherwise, if the VLIW packet spans two pages, where a first page is present as a TLB entry within the TLB module and the second page is missing from the stored TLB entries, an indication bit within a data field of a control register is set to identify the TLB miss exception to a software management unit.
