Abstract:
A method is shown that eliminates the need for a dedicated reorder buffer register bank or memory space in a multi level cache system. As data requests from the L2 cache may be returned out of order, the L1 cache uses it's cache memory to buffer the out of order data and provides the data to the requesting processor in the correct order from the buffer.
