Abstract
A data processing system includes a command buffer and control circuitry. The command buffer is configured to store pending write requests to a memory in which each pending write request has corresponding write data. The control circuitry is configured to select a pending write request from an entry of the command buffer and send the selected write request to the memory. The selected write request is a partial write request having first write data stored in the entry. Sending the selected write request includes performing a read-modify-write (RMW), wherein the control circuitry is configured to, after a read operation of the RMW, update the pending write request in the entry from a partial write request to a full write request.
