Each instruction is considered to be a separate process. Instructions do not refer- ence memory; instead, they reference other instructions. Data is passed from one instruction to the next. We can understand the computation sequence of a dataflow computer by examining its data flow graph . In a data flow graph, nodes represent instructions, and arcs indicate data dependencies between instructions. Data flows through this graph in the form of data tokens . When an instruction has all of the data tokens it needs, the node fires . When a node fires, it consumes the data tokens, performs the required operation, and places the resulting data token on an output arc. This idea is illustrated in Figure 9.11. The data flow graph shown in Figure 9.11 is an example of a static dataflow architecture in which the tokens flow through the graph in a staged pipelined fashion. In dynamic

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
