Control device for data stream optimizations in a link interface

摘要

Optimization logic that optimizes a stream of requests being transmitted onto a link by a link interface unit can be enabled or disabled based on a performance metric that represents a measure of the degree to which a response to a request is likely to be slowed due to congestion, propagation delays, or other bottlenecks in the system. For example, the performance metric can be based on a measured level of link activity due to requests from the transmitting device and/or a prediction as to behavior (e.g., access time) of the target device that receives the stream of requests. The control logic advantageously does not require extra signals to be carried on the bus.
