Abstract
A method and apparatus for providing asynchronous memory functions for bi-directional cell traffic in a switch platform are provided, wherein a parameterized bi-directional FIFO unit controls cell traffic in a switch platform using a first and a second unidirectional FIFO buffer. The first and second unidirectional FIFO buffers each comprises asynchronous read and write ports. A cell size and a word size of the first and second unidirectional FIFO buffers are programmable. The bi-directional FIFO unit is coupled to write at least one cell from and read at least one cell to at lest one asynchronous transfer mode (ATM) interface, at least one frame relay interface, at least one voice interface, and at least one data interface. As such, the first unidirectional FIFO buffer is coupled to write at least one cell from, and the second unidirectional FIFO buffer is coupled to read at least one cell to an ATM interface, a frame relay interface, a voice interface, and a data interface. The first unidirectional FIFO buffer is coupled to read at least one cell to at least one switch, and the second unidirectional FIFO buffer is coupled to write at least one cell from at least one switch, where…
