Here the datapath architectural optimizations are done at the gate level implementation for the processors used in PID applications. This paper briefs about the significance of datapath components in achieving the low power constraint. Nowadays embedded control applications requires low power and fast acting PID controllers with a closed loop performance using less resources, resulting in cost reduction. In this paper we present the novel digital proportional–integral–derivative (PID) controller architecture, based on the adder and multipliers which consumes lower power. Traditionally, the design and implementation of control systems are often separated, which causes the development of embedded control systems to be highly time-consuming and cost. Despite their popularity, embedded systems are generally subject to resource constraints and it is therefore difficult to build complex control systems on embedded platforms.
Embedded systems are playing an increasingly important role in control engineering.
