Introduction

This macro is used to instantiate AXI Memory Mapped (AXI Full) FIFO.

AXI4 FIFO is derived from the XPM_FIFO_SYNC and XPM_FIFO_ASYNC. The AXI interface protocol uses a two-way valid and ready handshake mechanism. The information source uses the valid signal to show when valid data or control information is available on the channel. The information destination uses the ready signal to show when it can accept the data.

Timing Diagrams

Figure 1. Timing for Read Operations to the AXI4 FIFO

Figure 2. Timing Write Operations to the AXI4 FIFO

In the timing diagrams above, the information source generates the valid signal to indicate when the data is available. The destination generates the ready signal to indicate that it can accept the data, and transfer occurs only when both the valid and ready signals are High.

Because AXI4 FIFO is derived from XPM_FIFO_SYNC and XPM_FIFO_ASYNC, much of the behavior is common between them. The ready signal is generated based on availability of space in the FIFO and is held high to allow writes to the FIFO. The ready signal is pulled Low only when there is no space in the FIFO left to perform additional writes. The valid signal is generated based on availability of data in the FIFO and is held High to allow reads to be performed from the FIFO. The valid signal is pulled Low only when there is no data available to be read from the FIFO. The information signals are mapped to the din and dout bus of XPM_FIFO_SYNC and XPM_FIFO_ASYNC. The width of the AXI4 FIFO is determined by concatenating all of the information signals of the AXI interface. The information signals include all AXI signals except for the valid and ready handshake signals.

AXI4 FIFO operates only in First-Word Fall-Through mode. The First-Word Fall-Through (FWFT) feature provides the ability to look ahead to the next word available from the FIFO without issuing a read operation. When data is available in the FIFO, the first word falls through the FIFO and appears automatically on the output data bus.
