B. Processing and Wireless Interface Subsystem<br>This part of the system consists of the Texas Instrument's CC2650 which integrate multiple hardware components (data processing, controlling sensing, communication) in a miniaturized (4mm ×4 mm) single chip. The microcontroller has a dual-core architecture with an ARM Cortex M3 for processing, an ARM Cortex M0 core dedicated to the Bluetooth communication and an autonomous sensor controller. The power-optimized sensor controller runs autonomously, allowing the rest of the processor to stay in standby mode. The direct access to peripherals makes the sensor controller perfectly suited for reading and writing sensor data as well as digital and analog inputs and outputs. The collected sensor data can be efficiently processed at any moment by the Cortex M3 CPU which is waked up by the sensor controller.Its energy efficient sensor controller is another reason why this processor has been selected for this work. The data from the oximeter can be acquired and stored in memory without involving the ARM Cortex M3, improving the energy efficiency of the whole system. The CC2650 also performs low power wireless communications with Bluetooth low energy. The current consumption is only 6.1mA in transmission mode at 0dBm, and 1 μA in standby, resulting in, to our knowledge, the lowest BTLE commercially available.1mA in transmission mode at 0dBm, and 1 μA in standby, resulting in, to our knowledge, the lowest BTLE commercially available.1mA in transmission mode at 0dBm, and 1 μA in standby, resulting in, to our knowledge, the lowest BTLE commercially available.
