1.2.8. Store Buffer

The Store Buffer (STB) holds store operations when they have left the load/store pipeline and have been committed by the DPU. From the STB, a store can request access to the cache RAM in the DCU, request the BIU to initiate linefills, or request the BIU to write the data out on the AXIM interface.

The STB can merge several store transactions into a single transaction if they are to the same 64-bit aligned address.
