24.3.1. FIFO Settings
Depth
Depth indicates the depth of the FIFO buffer, in Avalon® -ST bits or Avalon® -MM words. The default depth is 16. When dual clock mode is used, the actual FIFO depth is equal to depth-3. This is due to clock crossing and to avoid FIFO overflow.
The two options are Single clock mode and Dual clock mode. In Single clock mode, all interface ports use the same clock. In Dual clock mode, input data and input side status are on the input clock domain. Output data and output side status are on the output clock domain.
The optional status ports are Avalon® -MM agents. To include the optional input side status interface, turn on Create status interface for input on the Platform Designer MegaWizard. For FIFOs whose input and output ports operate in separate clock domains, you can include a second status interface by turning on Create status interface for output. Turning on Enable IRQ for status ports adds an interrupt signal to the status ports.
This option determines if the FIFO core is built from registers or embedded memory blocks. The default is to construct the FIFO core from embedded memory blocks.
