Abstract
Pipelined loop operations are efficiently scheduled. A preliminary as soon as possible (ASAP) schedule for a data operation in a pipelined loop is determined. A producer operation clock cycle associated with a producer operation in the pipelined loop is determined. The producer operation provides a data value for use by the data operation in a subsequent loop. A consumer operation clock cycle associated with a consumer operation in the pipelined loop is determined. The consumer operation obtains the data value from the data operation in a previous loop. The data operation is scheduled at the half-way point between the producer operation clock cycle and the consumer operation clock cycle.
