PROBLEM TO BE SOLVED: To provide a computer monitoring interrupts from a plurality of data sources and performing transfer of data without missing. SOLUTION: The computer 100 includes: a plurality of data buffer circuits 4-1 to 4-N for temporarily holding a plurality of pieces of the data and sending them to an MPU (Micro Processing Unit); a plurality of interrupt signal edge detection circuits 2-1 to 2-N sequentially detecting change points from interrupt request signals from the data sources 1-1 to 1-N and generating edge signals; a plurality of FIFO (First In First Out) buffer circuits 3-1 to 3-N temporarily holding the edge signals from the interrupt signal edge detection circuits 2-1 to 2-N; an interrupt sampler circuit 5 registering outputs of the FIFO buffer circuits 3-1 to 3-N into a queue; and an interrupt controller 6 reading the queue of the interrupt sampler circuit 5 and generating an interrupt signal to the MPU 7.
