One embodiment of the present invention provides a system that facilitates phase-buffering on a bit-by-bit basis using a control queue. The system includes a control queue, wherein a stage in the control queue is configured to accept both a first control signal and a second control signal, wherein the first control signal and the second control signal are mutually exclusive, wherein the first control signal being asserted indicates the value of a corresponding bit is zero, while the second control signal being asserted indicates the value of the corresponding bit is one. A forward-transfer mechanism couples the first control signal or the second control signal from the input of the stage through storage elements to the output of the stage. A reverse transfer mechanism accepts an acknowledgement signal at the output of the stage and transfers the acknowledgement signal through a storage element to the input of the stage.
