ABSTRACT:
In an interrupt-driven data frame stream receiver, an interrupt to a host processor is applied by an interrupt system that comprises a timer logic circuit, an address match circuit, a data frame counter, a cyclic redundancy check (CRC) logic circuit, a frame length logic circuit, and a frame content detector. Each of these circuits is coupled to an OR gate. A Start Frame Delimiter (SFD) detector is connected to the inputs of the other circuits. The interrupt system provides the interrupts when any one or more of the following conditions arise: 1) a time interval between successive frames in the data frame stream is equal to or greater than a predetermined value, 2) a predetermined maximum number of frames have been received, 3) a frame is not addressed to the receiver, 4) an error frame is received, 5) the length of a frame is less than a minimum preset value, 6) the length of a frame is more than a maximum preset value, 7) frames have been received for a time period that exceeds a predetermined time period, and 8) the content of a frame requests the frame to be handled in a prescribed manner.
