Latest Patents

One of Ryan's latest patents is the "Frequency Independent Asynchronous Clock Crossing FIFO." This invention is a clock crossing FIFO capable of functioning regardless of the relative clock frequencies on the write and read sides. Toggle signals are utilized to cross the clock boundaries. The number of write counts that have been accrued but not acknowledged by the read side are tracked and stored as of the issuance of a write toggle. Upon toggle receipt on the read side, this number is latched as a measure of the number of data units that can be read from the FIFO. At the same time, the toggle is returned to the write side for decrementing the number of write counts outstanding by the number conveyed to the read side. Similar circuitry is employed for conveying to the write side circuitry the number of data units that have been read by the read side circuitry. The presently disclosed FIFO and associated circuitry operate independently of relative clock speeds, and the particular size of the FIFO is scalable.

Another significant patent is the "Method and Apparatus for VLAN Support." In this invention, logic circuits are employed in a telecommunications bridge/router device to examine a received frame to determine which VLAN, if any, the frame is associated with. The protocol type, receive port identification, and receive VLAN tag are utilized to determine the transmit port identification and transmit VLAN tag. A predefined table indicates which ports within the bridge/router are associated with the VLAN. The frame is excluded from transmission through the ports that are not associated with members of the respective VLAN.
