Working Principle of the AT91RM9200-EK Evaluation Board

The AT91RM9200-EK evaluation board is based on the AT91RM199 microcontroller (MCU), which features an architecture that is based on a 32-bit RISC processor. The board includes a 27MHz dual processor, a 144-pin EJTAG developed by Atmel, and a powerful 120MHz digital signal processor (DSP). This combination allows for an efficient and powerful system of instruction set and data manipulation.

The MCU consists of multiple layers where information is stored and handled on each layer. The inputs from different components such as the switch, which is connected to the controller, is sent through serial communication to the MCU. The MCU further receives the data and it is then parallelised to the DSP. The DSP is the layer where the data is processed into a digital signal that could be read or written onto different components.

The AT91RM9200-EK evaluation board also features an embedded debugger for debugging and executing programs. The debugger can be used to easily monitor and alter the functions of the board during run-time. This feature can be used to check and debug the system\'s response and ensures that the system performs as expected.

Conclusion

In conclusion, the AT91RM9200-EK evaluation board is an ideal platform for developing embedded applications for professional and scientific usage. The board consists of a powerful microcontroller and digital signal processor which allows for an efficient system design with robust performance. As the board has obtained certification for conformance to the European standard, it is widely used for developing systems for various industries and consumer electronic products.
