Abstract
A circuit generally comprising a queue having an input and an output. The queue may be used to buffer memory requests generated by a processor to access a memory. The input may be configured to receive a plurality of memory requests. The memory requests may include a plurality of write requests and a plurality of read requests. The output may be configured to present the memory requests. The queue may be configured to (i) store the memory requests received at the input in an arrival order, (ii) rearrange the memory requests by propagating each read request ahead of each write request to establish a presentation order, and (iii) present the memory requests at the output in the presentation order.
