ABSTRACT:
A method for generating an interrupt signal for a media access controller (MAC) in communication with a computer host and an external network is disclosed. The method includes steps of asserting an interrupt signal to the computer host when at least one data packet is to be transferred from a memory, performing a corresponding interrupt service of the computer host in response to the interrupt signal for freeing a memory space occupied by the data packet being transferred from the memory, and deasserting the interrupt signal until the corresponding interrupt service is finished and a predetermined delay period is up. In addition, a media access controller (MAC) is also disclosed. The MAC includes a timer for counting a predetermined delay period after the interrupt service has been finished.
