3.2.1. Interfaces
Avalon® -ST Data Interface
Each FIFO core has an Avalon® -ST data sink and source interfaces. The data sink and source interfaces in the dual-clock FIFO core are driven by different clocks.
Feature | Property |
---|---|
Backpressure | Ready latency = 0. |
Data Width | Configurable. |
Channel | Supported, up to 255 channels. |
Error | Configurable. |
Packet | Configurable. |
Avalon® -MM Control and Status Register Interface
You can configure the single-clock FIFO core to include an optional Avalon® -MM interface, and the dual-clock FIFO core to include an Avalon® -MM interface in each clock domain. The Avalon® -MM interface provides access to 32-bit registers, which allows you to retrieve the FIFO buffer fill level and configure the almost-empty and almost-full thresholds. In the single-clock FIFO core, you can also configure the packet and error handling modes.
Avalon® -ST Status Interface
The single-clock FIFO core has two optional Avalon® -ST status source interfaces from which you can obtain the FIFO buffer almost-full and almost empty statuses.
