Abstract
Problem statement: In an advanced electronics world most of the applications are developed by microcontroller based embedded system. Approach: Multicore processor based motor controller was presented to improve the processing speed of the controller and improve the efficiency of the motor by maintaining constant speed. It was based on the combination of Cortex processor (Software core) and Field Programmable Gate Arrays (FPGA, Hardware core). These multicore combination were help to design efficient low power motor controller. Results: A functional design of cortex processor and FPGA in this system was completed by using Actel libero IDE and IAR embedded IDE software PWM signal was generated by the proposed processor to control the motor driver circuit. All the function modules were programmed by Very-High-Speed Integrated Circuit Hardware Description Language (VHDL). The advantage of the proposed system was optimized operational performance and low power utility. Multicore processor was used to improve the speed of execution and optimize the performance of the controller. Conclusion: Without having the architectural concept of any motor we can control it by using this method.This is an low cost low power controller and easy to use. The simulation and experiment results verified its validity.
Highlights
In an electronic era the requirement of electronic systems are increased exponentially
Hardware structure: Based on the structure of multicore processor combination the Hardware circuit is designed to perform the better control of PMDC motor .Hardware circuit consists of buffer optocoupler, Driver circuit
Experimental: To test the entire setup newly configured multicore processor is generated in the actel fusion device by using High Performance Reprogrammable Flash Technology
Summary
In an electronic era the requirement of electronic systems are increased exponentially. The size of the system must be reduced for betterment of easy way of using. Power requirement is to be considering while designing such a systems. A day some of the advanced 32 bits processors are used to design an embedded based electronic system. ARM 7 (Advanced RISC Machine) processor is widely used to design PDAs, Controllers for Automation, LCD monitors and 3G mobile phones. Instead of using single core processor like ARM core if we use more than one core ie., multicore processor to establish a single task, we may get better performance and very high throughput
