  • Method and apparatus for generating massive interrupts in random access memory (RAM)
    Patent number: 6633573
    Abstract: A method and apparatus for generating massive interrupts in random access memory (RAM) are provided, comprising receiving and storing Time Slot network (TS Net) data frames comprising switching event information in a first RAM area. Compare operations are performed among prespecified ones of the TS Net data frames. Unit interrupt bits are set in a corresponding location of a second RAM area in response to detected bit differences resulting from the compare operations. Interrupt status bits are set in a corresponding location of a third RAM area in response to set unit interrupt bits. Massive interrupt signals are generated in response to set unit interrupt bit.
