The authors present a transactional datapath specification and the tool to synthesize automatically an in-order pipelined implementation from it. T-spec abstractly views a datapath as executing one transaction at a time, computing next system states based on current ones. From a T-spec, T-piper can synthesize a pipelined implementation that preserves original transaction semantics, while allowing simultaneous execution of multiple overlapped transactions across pipeline stages. T-piper not only ensures the correctness of pipelined executions, but can also employ forwarding and speculation to minimize performance loss due to data dependencies.
