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 .
Function Block Diagram is one of five languages for logic or control configuration [2] supported by standard IEC 61131-3 for a control system such as a programmable logic controller (PLC) or a Distributed Control System (DCS). The other supported languages are ladder logic, sequential function chart, structured text, and instruction list.
In compiler construction, a basic block is a straight-line code sequence with no branches in except to the entry and no branches out except at the exit. [1] [2] This restricted form makes a basic block highly amenable to analysis. [3] Compilers usually decompose programs into their basic blocks as a first step in the analysis process.
68HC11 block diagram. Internally, the HC11 instruction set is backward compatible with the 6800 and features the addition of a Y index register. [a] It has two eight-bit accumulators, A and B, two sixteen-bit index registers, X and Y, a condition code register, a 16-bit stack pointer, and a program counter. In addition, there is an 8 x 8-bit ...
Block diagram of a basic computer with uniprocessor CPU. Black lines indicate control flow, whereas red lines indicate data flow. Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1]
With system identification, the plant model is identified by acquiring and processing raw data from a real-world system and choosing a mathematical algorithm with which to identify a mathematical model. Various kinds of analysis and simulations can be performed using the identified model before it is used to design a model-based controller.
A block diagram of a PID controller in a feedback loop. r(t) is the desired process variable (PV) or setpoint (SP), and y(t) is the measured PV. The distinguishing feature of the PID controller is the ability to use the three control terms of proportional, integral and derivative influence on the controller output to apply accurate and optimal ...
The IC is capable of interpreting and executing program instructions and performing arithmetic operations. [1] The microprocessor is a multipurpose, clock -driven, register -based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory , and provides results (also in binary form ...
