Abstract
An interrupt control device between clock domains is provided. An interrupt sharing logic is configured to receive one or more original interrupt signals and generate a combined interrupt signal. An interrupt processing logic is configured to output a processed interrupt signal to a processor according to the combined interrupt signal, so that the processor executes an interrupt service routine. When the interrupt service routine is executed, the processed interrupt signal changes to be disabled; before the interrupt service routine is completed, the processor outputs an interrupt clear signal to change the respective interrupt signal to be negated. After the interrupt processing logic detects that interrupt signal has been cleared successfully, the interrupt processing logic will generate the processed interrupt signal according to the combined interrupt signal again.
