Abstract: If a first group selection setting is set to TRUE, an NVM Express (NVMe) processor sends a first set of NVMe status information that includes a transfer data end event. If a second group selection setting is set to TRUE, the NVMe processor sends a second set of NVMe status information that includes an NVMe error event. A firmware functional module sends firmware status information. The aggregation module aggregates and timestamps the first and second sets of NVMe status information, if any, and the firmware status information to obtain a timestamped and aggregated message stream that is output by an interface. The timestamped and aggregated message stream enables a visualization system to analyze the NVMe processor and the firmware functional module. The NVMe processor, firmware functional module, aggregation module, and interface are in a storage controller, implemented on a system on chip (SOC), that manages a storage medium.

Abstract: A hardware functional module performs a given task. A first notification that the given task has completed and which includes a scoreboard identifier is sent to a scoreboard module. The scoreboard module selects a scoreboard counter based on the scoreboard identifier. The selected scoreboard counter is incremented. It is determined whether the selected scoreboard counter exceeds a corresponding scoreboard threshold. If the selected scoreboard counter exceeds the corresponding scoreboard threshold, a second notification indicating that the plurality of tasks has completed is sent. If the scoreboard identifier corresponds to the host command module, the second notification is sent to the host command module. If the scoreboard identifier corresponds to the backend command module, the second notification is sent to the backend command module.

Abstract: A storage controller system includes a host command module that manages communication with a host and a backend command module that manages communication with a storage system. A storage interface hardware functional module, in response to an unsuccessful or successful operation, generates a first or second type of a status message with an automated retry flag set to TRUE or FALSE. A virtual queue module receives the status message and selects a virtual queue. If (1) the flag being set to TRUE and (2) independent of the queue ID, an original command virtual queue is selected. If (1) the flag being set to FALSE and (2) the queue ID being set to the value associated with the backend command module, a virtual queue associated with the backend command module is selected. A stored message in the selected virtual queue is provided to the selected message recipient.

Abstract: A hardware functional module sends, to an aggregation module and in a standardized message format, first status information associated with the hardware functional module according to a first set of reporting rules via a first dedicated link. The firmware functional module sends, to the aggregation module and in the standardized message format, second status information associated with the firmware functional module according to a second set of reporting rules via a second dedicated link. The aggregation module aggregates the first status information in the standardized message format and the second status information in the standardized message format and inserts a timestamp to obtain a timestamped and aggregated message stream. The timestamped and aggregated message stream enables a visualization system to analyze the hardware functional module and the firmware functional module.

Abstract: A controller of a power conversion circuit generates PWM signals to control output stage circuits to provide an output voltage and a load current to an output terminal. The controller includes a sensing circuit, a comparison circuit, a PWM generation circuit and a control loop. The sensing circuit generates a current sensing signal related to load current. The comparison circuit compares the current sensing signal and a default value representing a current threshold to generate a comparison result. The control loop, coupled to the output terminal, the PWM generation circuit and the comparison circuit, generates a trigger signal according to a reference voltage and the output voltage to control the PWM generation circuit to generate PWM signals. When the comparison result indicates that the load current exceeds current threshold, the control loop temporarily stops providing trigger signal to PWM generation circuit to delay the generation of PWM signals.
