-- The FIFO Generator is a parameterizable first-in/first-out memory queue generator. Use it to generate resource and performance optimized FIFOs with common or independent read/write clock domains, and optional fixed or programmable full and empty flags and handshaking signals.  Choose from a selection of memory resource types for implementation.  Optional Hamming code based error detection and correction as well as error injection capability for system test help to insure data integrity.  FIFO width and depth are parameterizable, and for native interface FIFOs, asymmetric read and write port widths are also supported.

-- Interfaces:

--    AXIStream_MASTER_M_AXIS

--    AXIStream_SLAVE_S_AXIS

--    AXI4_MASTER_M_AXI

--    AXI4_SLAVE_S_AXI

--    AXILite_MASTER_M_AXI

--    AXILite_SLAVE_S_AXI

-- The following code must appear in the VHDL architecture header:
