Abstract
A method and apparatus for ordering operations and data received by a first bus having a first ordering policy according to a second ordering policy which is different from the first ordering policy, and for transferring the ordered data on a second bus having the second ordering policy. The system includes a plurality of execution units for storing operations and executing the transfer of data between the first and second buses. Each one of the execution units are assigned to a group which represent a class of operations. The apparatus further includes intra prioritizing means, for each group, for prioritizing the stored operations according to the second ordering policy exclusive of the operation stored in the other group. The system also includes inter prioritizing means for determining which one of the prioritized operations can proceed to execute according to the second ordering policy.
