24.3.2. Interface Parameters
Input
Available input interfaces are Avalon® Memory-Mapped Interface write agent and Avalon® Streaming Interface sink.
Output
Available output interfaces are Avalon® Memory-Mapped Interface read agent and Avalon® Streaming Interface source.
Allow Backpressure
When Allow backpressure is on, an Avalon® Memory-Mapped Interface includes the waitrequest signal which is asserted to prevent a host from writing to a full FIFO buffer or reading from an empty FIFO buffer. An Avalon® Streaming Interface includes the ready and valid signals to prevent underflow and overflow conditions.
Avalon® Memory-Mapped Interface Port Settings
Valid Data widths are 8, 16, and 32 bits.
If Avalon® Memory-Mapped Interface is selected for one interface and Avalon® Streaming Interface for the other, the data width is fixed at 32 bits.
The Avalon® Memory-Mapped Interface accesses data 4 bytes at a time. For data widths other than 32 bits, be careful of potential overflow and underflow conditions.
Avalon® Streaming Interface Port Settings
The following parameters allow you to specify the size and error handling of the Avalon® Streaming Interface port or ports:
- Bits per symbol
- Symbols per beat
- Channel width
- Error width
If the symbol size is not a power of two, it is rounded up to the next power of two. For example, if the bits per symbol is 10, the symbol will be mapped to a 16-bit memory location. With 10-bit symbols, the maximum number of symbols per beat is two.
Enable packet data provides an option for packet transmission.
