  • Interrupt handler with prioritized interrupt vector generator
    Patent number: 6499078
    Abstract: A hardware-implemented interrupt handler external to a processor handles interrupts destined for the processor. The interrupt handler has a programmable prioritized interrupt array with programmable registers that identify priority levels and handling processes for handling one or more interrupts. The interrupt handler also has an interrupt scanning state machine that scans the prioritized interrupt following receipt of an interrupt to extract the priority level and handling process associated with the interrupt. The interrupt handler is designed to handle interrupts in significantly less time than software implementations, thereby making the handler favorable for real time systems.
