WebAltera provides FIFO functions through the parameterizable single-clock FIFO (SCFIFO) and dual-clock FIFO (DCFIFO) megafunctions. The FIFO functions are mostly applied in data buffering applications that comply with the first-in-first-out data flow in synchronous or asynchronous clock domains. The specific names of the megafunctions are as follows: Webaxi_fifo module. AXI FIFO with parametrizable data and address interface widths. Supports all burst types. Optionally can delay the address channel until either the write data is completely shifted into the FIFO or the read data FIFO has enough capacity to fit the whole burst.
