Editing Dataflow architecture (section)

=== Programs ===
Programs are loaded into the CAM of a dynamic dataflow computer. When all of the tagged operands of an instruction become available (that is, output from previous instructions and/or user input), the instruction is marked as ready for execution by an [[execution unit]]. 

This is known as ''activating'' or ''firing'' the instruction. Once an instruction is completed by an execution unit, its output data is sent (with its tag) to the CAM. Any instructions that are dependent upon this particular datum (identified by its tag value) are then marked as ready for execution. In this way, subsequent instructions are executed in proper order, avoiding [[race condition]]s. This order may differ from the sequential order envisioned by the human programmer, the programmed order.
