ABSTRACT:
An apparatus and method of operating a cascadable, instant-fall-through First In, First Out (FIFO) buffer is provided. The method comprises receiving a first data element at an input of a FIFO buffer which includes a plurality of buffer slices including an output buffer slice wherein each of the plurality of buffer slices comprise a data register and a control bit register. A buffer slice is identified which is indicated for storing a data element based on a control bit register for the buffer slice and a control bit register of an adjacent buffer slice on an output side. When data is read from an output buffer slice the FIFO buffer, all data in other buffer slices are shifted down one slice closer to the output side of the FIFO buffer.
