This section defines two basic concepts before introducing the transfer types:
- Transfer—A transfer is a read or write operation of a word or one or more symbol of data. Transfers occur between an Avalon® -MM interface and the interconnect. Transfers take one or more clock cycles to complete.
Both hosts and agents are part of a transfer. The Avalon® -MM host initiates the transfer and the Avalon® -MM agent responds.
- Host-Agent pair—This term refers to the host interface and agent interface involved in a transfer. During a transfer, the host interface control and data signals pass through the interconnect fabric and interact with the agent interface.
