A Study on ARM Cortex M3 Based Hardware Debugging

Modern embedded systems are based on microcontroller and microprocessors, mostly in more complex systems. Embedded system is meant for specific software and hardware integration task. The design engineers can optimize it to reduce the size and cost of the product and increase the reliability and performance. High throughput reduction circuits are typically hand designed for specific controlling. In this paper, a new design approach that hardware debugging and programming through USB using ARM cortex M3 architecture. Processor selection, programming options, debug and trace, operating voltage, cost, size and support are the important criteria’s that need to be considered while selection is made. The proposed technique debugging, is a computer program that is used to test and debug target program, consisting of a hardware implemented module that performs hardware debugging through the available JTAG based On-Chip Debugger. This approach can be applied to many microcontrollers, since JTAG is widely supported interface.
