A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .
Between B and C: heat sink for switching active devices of primary voltage; C: transformer: Between C and D: heat sink for switching active devices of at least five secondary voltages, per the ATX specification; D: output filter coil for the secondary with the largest power rating. In close proximity, filter coils for the other secondaries;
The common approach when working with FMC is to start with a high-level diagram of the compositional structure of a system. This “big picture” diagram serves as a reference in the communication with all involved stakeholders of the project. Later on, the high-level diagram is iteratively refined to model technical details of the system ...
A functional block diagram, in systems engineering and software engineering, is a block diagram that describes the functions and interrelationships of a system. The functional block diagram can picture: [1] functions of a system pictured by blocks; input and output elements of a block pictured with lines; the relationships between the functions ...
A block diagram of a PID controller in a feedback loop, r(t) is the desired process value or "set point", and y(t) is the measured process value. A proportional–integral–derivative controller (PID controller) is a control loop feedback mechanism control technique widely used in control systems.
Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and views of a system. [1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.
Starting from a leader, the set of all following instructions until and not including the next leader is the basic block corresponding to the starting leader. Thus every basic block has a leader. Instructions that end a basic block include the following: unconditional and conditional branches, both direct and indirect; returns to a calling ...
