A multiplexor for an Improved Inter-Integrated Circuit (I3C) network includes a switch, a snooper, and an I3C slave module coupled to an I3C master interface. The switch selectably couples I3C busses to the I3C master interface. Each I3C bus incudes I3C slave interfaces. The selected I3C bus is the active bus, and the non-selected I3C busses are inactive buses. The snooper detects In-Band Interrupts (IBIs) from the I3C slave interfaces coupled to the inactive buses. When the snooper receives a first IBI on an inactive bus, the snooper provides an indication. The I3C slave module provides a second IBI to the I3C master interface in response to the indication.

In one embodiment, a processor comprises a fabric interconnect to couple a first cache agent to at least one of a memory controller or an input/output (I/O) controller; and a first cache agent comprising a cache controller coupled to a cache; and a trace and capture engine to periodically capture a snapshot of state information associated with the first cache agent; trace events to occur at the first cache agent in between captured snapshots; and send the captured snapshots and traced events via the fabric interconnect to the memory controller or I/O controller for storage at a system memory or storage device.

Systems, methods, and devices for monitoring operation of industrial equipment are disclosed. In one embodiment, a monitoring system is provided that includes a passive backplane and one more functional circuits that can couple to the backplane. Each of the functional circuits that are coupled to the backplane can have access to all data that is delivered to the backplane. Therefore, resources (e.g., computing power, or other functionality) from each functional circuits can be shared by all active functional circuits that are coupled to the backplane. Because resources from each of the functional circuits can be shared, and because the functional circuits can be detachably coupled to the backplane, performance of the monitoring systems can be tailored to specific applications. For example, processing power can be increased by coupling additional processing circuits to the backplane.

A processing device includes: a first processor configured to execute a determination process; and a second processor configured to communicate with the first processor via an internal bus, wherein the determination process includes processes of determining that the abnormality occurs inside the processing device when first reference data transmitted to the second processor and first diagnostic data that is response data to the first reference data do not correspond to each other, and determining that the abnormality occurs in at least one of an external bus or an external device when the first reference data and the first diagnostic data correspond to each other and second reference data transmitted to the external device and second diagnostic data that is response data to the second reference data do not correspond to each other.

A system for monitoring inter-integrated circuit (12C) communication includes a power supply, a battery backup unit, an 12C serial clock line (SCL) coupled between the power supply and the battery backup unit, an 12C serial data line (SDA) coupled between the power supply and the battery backup unit, and a controller. A first monitor line is coupled between the controller and the 12C serial clock line, and a second monitor line is coupled between the controller and the 12C serial data line. The controller is configured to monitor a digital communication transmitted on the 12C serial clock and data lines between the power supply and the battery backup unit, interpret a message included in the monitored digital communication, and perform a control function according to the interpreted message.

Embodiments of the present disclosure relate to controlling bandwidth allocations of storage system ports. A maximum bandwidth of one or more ports of the storage device for receiving migration data from a remote storage device are dynamically allocated based on one or more state metric of a storage device. The migration data is migrated from the remote storage device based on each port's bandwidth allocation.

The present disclosure provides systems and methods for performance evaluation of Input/Output (I/O) intensive enterprise applications. Representative workloads may be generated for enterprise applications using synthetic benchmarks that can be used across multiple platforms with different storage systems. I/O traces are captured for an application of interest at low concurrencies and features that affect performance significantly are extracted, fed to a synthetic benchmark and replayed on a target system thereby accurately creating the same behavior of the application. Statistical methods are used to extrapolate the extract features to predict performance at higher concurrency level without generating traces at those concurrency levels. The method does not require deploying the application or database on the target system since performance of system is dependent on access patterns instead of actual data. Identical access patterns are re-created using only replica of database files of the same size as in the real database.

Multiple data paths may be available to a data management system for transferring data between a primary storage device and a secondary storage device. The data management system may be able to gain operational advantages by performing load balancing across the multiple data paths. The system may use application layer characteristics of the data for transferring from a primary storage to a backup storage during data backup operation, and correspondingly from a secondary or backup storage system to a primary storage system during restoration.

By extending a Basic-CAN controller and/or a Full-CAN controller with a RX filter device, it is possible to compare the CAN identifiers intended for transmission for the CAN controller with those of the received CAN frames. In the case of a match, an interrupt is generated. When no hardware expansion is intended, the RX-FIFO or TX-FIFO of a Full-CAN controller is used for detecting an intrusion.

The system, method, and computer program product described herein provide ways to modify a user interface when a performance of the user interface degrades due to lack of resources including presenting the user interface to a user that includes a first element that requires an allocation of a first amount of resources of a server to perform a function, determining that a performance of the user interface has degraded below a threshold amount, in response to determining that the performance has degraded, identifying a second element that requires an allocation of a second amount of resources of the server to perform the function where the second amount of resources is smaller than the first amount of resources, and replacing the first element with the second element to reduce the required amount of resources that are allocated by the server to the user interface.
