Abstract
A system and method for using a single shared buffer to service multiple destinations for a telecommunications switch is disclosed. Upon receiving a cell of data to be sent to a destination, an interface stores the cell in a shared buffer. The address of the cell in the buffer is stored in a queue array. The address of the buffer address in the queue array is stored in a head array and a tail array. A threshold register tracks the global threshold for the total number of cells in the shared buffer and a destination threshold for each destination. The buffer can broadcast a data cell to a single location or send the same cell to multiple locations.
