ABSTRACT:
A method for controlling cell transmission on a basis of 1 byte between FIFOs of a UTOPIA interface, thereby performing cell transmission more speedily and more smoothly, which is achieved by advancing start timing of cell transmission by defining active timing of cell enable signal and cell available (CA) signal between FIFOs of the UTOPIA interface to a moment when a 1-byte data is available. The CA signal becomes active (high signal) when a TX FIFO has data with greater than 1 byte and a RX FIFO is able to receive data with greater than 1 byte. The cell enable (Enb) signal becomes active when an input CA signal in the TX FIFO is in a ‘high’ state and the TX FIFO has data with greater than 1 byte to be transmitted, and when an input CA signal in the RX FIFO is in a ‘high’ state and the RX FIFO is able to receive data with greater than 1 byte. As a result, a cell can be transmitted much faster as much as 52 bytes*clock and traffic performance of system can be improved considerably.
