WebFIFO Parameter Settings. Table 3. FIFO Parameters. Specifies the width of the data and q ports for the SCFIFO function and DCFIFO function. For the DCFIFO_MIXED_WIDTHS function, this parameter specifies only the width of the data port. Specifies the width of the q port for the DCFIFO_MIXED_WIDTHS function. WebDCFIFO Group Setting for Latency and Related Options This table shows the available group setting. Group Setting Comment; Lowest latency but requires synchronized clocks: This option uses one synchronization stage with no metastability protection. It uses the smallest size and provides good f MAX.

WebFigure 1 shows the input and output ports of the SCFIFO and DCFIFO megafunctions. For the SCFIFO block, the read and write signals are synchronized to the same clock; for the DCFIFO block, the read and write signals are synchronized to the rdclk and wrclk clocks respectively. The prefixes wr and rd represent the signals that are Web• DCFIFO: dual-clock FIFO (supports same port widths for input and output data) • DCFIFO_MIXED_WIDTHS: dual-clock FIFO (supports different port widths for input and output data) Note: The term “DCFIFO” refers to both the DCFIFO and DCFIFO_MIXED_WIDTHS functions, unless specified.
