Abstract

The present invention provides a method and apparatus for optimizing bus utilization while maintaining read and write coherence. More specifically the invention provides bus utilization optimization by prioritizing read transactions before write transactions, where there is no collision pending. When a collision pending is determined, then the read and write transactions are processed according to the age of the transaction(s) allowing for data coherency.
