Latest Patents

RuiHong Liu holds a patent titled "Centralized interrupt handling for chiplet processing units." This patent describes systems, apparatuses, and methods for implementing a centralized interrupt controller that aggregates interrupts generated across multiple semiconductor dies. The system includes multiple interrupt sources on various semiconductor dies. A centralized interrupt controller on one of the semiconductor dies receives and aggregates interrupts from these sources. This design facilitates a single transmission point for forwarding interrupts to the processor and operating system responsible for handling them. Each interrupt source embeds an ID when conveying an interrupt to the interrupt controller, allowing the controller to differentiate between sources and identify which generated a given interrupt. The interrupt controller conveys an indication of the source of the interrupt to the processor when forwarding it.
