<p>In an ATM reception packet timeout detecting method, a timeout of an ATM reception packet is detected by using a CAM on the reception side of an ATM communication controller. An ATM reception packet timeout detecting apparatus includes a CAM, a write/search mode switching section, a timer section, and an adder. The CAM is made up of a selector for switching input data in accordance with a write/search mode, a cell array in which a timeout detection time is registered, an address decoder for decoding the write/read address of contents of the cell array from a reception VC, and a priority encoder for outputting a coincidence signal and a coincidence address on the basis of outputs from the cell array. The timer section has a counter that is incremented in synchronism with a system clock supplied from a system bus side. The adder adds the timeout allowable time for each VC to the counter value of the timer section. <IMAGE></p> |
