Abstract
A method and apparatus for combined transaction reordering and buffer management. The apparatus may include a buffer, a first generator circuit and a second generator circuit. The buffer is configured to store memory transaction responses received from a memory controller in a plurality of addressable locations. The first generator circuit is configured to generate a first memory transaction request encoded with a first tag corresponding to an address in the buffer in response to receiving a first memory request. The second generator circuit is configured to generate a second tag using the size of said first memory request added to the first tag. The first generator circuit may be further configured to generate a second memory transaction request encoded with the second tag corresponding to a second address in the buffer in response to receiving a second memory request successive to the first memory request. The second generator circuit may be further configured to generate a third tag using the size of the second memory request added to said second tag.
