Architecture design of the high integrated System-on-Chip for biomedical applications

The article describes a new microchip measuring technology known as “BioSystem-on-Chip” (BioSoC). The solution will consist of an application-specific integrated circuit containing analog/digital signal processing circuits and a microcontroller for signal processing and analysis. Dedicated interfaces will enable measuring psycho-physiological signals immediately after connecting external measurement sensors, without the need for any calibration. The integrated microcontroller core will ensure necessary control capabilities and the processing and analysis of measurands. The BioSoC´s structure will enable designing a complete monitoring and diagnostic system using a minimum number of discrete components. This approach will make the BioSoC integrable with new generation smartphones, without limitation, allowing for adding innovative human physiology monitoring functionalities. The proposed BioSoC architecture contains analog front-end circuits (with alternative designs available), an analog/digital processing circuit supported by DMA channels, a dedicated autonomous sampling engine, a 32-bit processor with integral SRAM, and required peripherals.
