4.5.1.1.1. Implementing Command Pipelining (Host-to-Agent)

When multiple hosts share an agent device, you can use command pipelining to improve performance.

The arbitration logic for the agent interface must multiplex the address, writedata, and burstcount signals. The multiplexer width increases proportionally with the number of hosts connecting to a single agent interface. The increased multiplexer width may become a timing critical path in the system. If a single pipeline bridge does not provide enough pipelining, you can instantiate multiple instances of the bridge in a tree structure to increase the pipelining and further reduce the width of the multiplexer at the agent interface.
