Summary:In this paper, a highly-integrated multiprocessor chip design enabling the real-time processing of biomedical signals in portable brain-heart monitoring systems is presented. The architecture comprises a novel diffuse optical tomography (DOT) processor for taking brain imaging, an independent component analysis (ICA) processor for removing artifacts of brain electroencephalogram (EEG) signals, and a heart rate variability (HRV) analysis processor for monitoring heart electrocardiogram (ECG) signals. The multiprocessor chip implemented in 65nm CMOS technology comprises 368k gates and occupies a core area of 462k μm 2 . Simulated power consumption using a full operation test case reports 3.6mW under the condition of 1.0V core supply voltage and 24MHz clock operating frequency.
