In this paper, modular design of embedded feedback controllers using the Field Programmable Gate Array (FPGA) technology is presented. To this end, a novel Distributed Arithmetic (DA)-based Proportional Integral Derivative (PID) controller algorithm is implemented and integrated into a digital feedback control system. The DA-based PID controller savings 80% hardware utilization to the multiplier-based scheme. It also offers good closed-loop performance while using less resource, resulting in cost reduction, high speed, and low power consumption, which is desirable in embedded control applications. The complete digital control system is built using commercial FPGAs to control a simple temperature loop
