Abstract
An embodiment of a method of high-level synthesis of a dataflow pipeline is disclosed. This embodiment includes obtaining processes from the high-level synthesis of the dataflow pipeline. A schedule for read operations and write operations for first-in, first-out data channels of the processes is determined. A dataflow through the dataflow pipeline for the schedule is determined. An edge-weighted directed acyclic graph for the processes and the dataflow is generated. A longest path in the edge-weighted directed acyclic graph is located. A weight for the longest path is output as an estimate, such as a latency estimate for example, for the dataflow.
