1.2. Signal Roles

Each Avalon® interface defines signal roles and their behavior. Many signal roles are optional. You have the flexibility to select only the signal roles necessary to implement the required functionality. For example, the Avalon® -MM interface includes optional beginbursttransfer and burstcount signal roles for components that support bursting. The Avalon® -ST interface includes the optional startofpacket and endofpacket signal roles for interfaces that support packets.

Except for Avalon® Conduit interfaces, each interface may include only one signal of each signal role. Many signal roles allow active-low signals. Active-high signals are generally used in this document.
