With the rapid advances in small, low-cost wearable computing technologies, there is a tremendous opportunity to develop personal health monitoring devices capable of continuous vigilant monitoring of physiological signals. Wearable biomedical devices have the potential to reduce the morbidity, mortality, and economic cost associated with many chronic diseases by enabling early intervention and preventing costly hospitalizations. These low power systems require to have the capacity to provide fast and accurate processing and interpretation of vast amounts of data and generate smart alarms only when warranted. The objective of this project is to build the foundation of the next generation of heterogeneous biomedical signal processing platforms that can address the current and future generation energy-efficiency requirements and computational demands. The PIs start with understanding the specific characteristics of emerging biomedical signal and imaging applications on off-the-shelf embedded low power multicore CPU, GPU and FPGA platforms to accurately understand the trade-offs they offer and the bottlenecks they have. Based on these results, the PIs will design and architect a domain-specific manycore accelerator in hardware and integrate it with an off-the-shelf embedded processor that together combine performance, scalability, programmability, and power efficiency requirements for these applications. The PIs will implement the proposed heterogeneous architecture in hardware and will evaluate its performance and power efficiency with a number of real-life biomedical workloads including seizure detection, handheld ultrasound spectral Doppler and imaging, tongue drive assistive device and prosthetic hand control interface.The proposed interdisciplinary research effort could inspire and enable new approaches to healthcare monitoring, and can significantly impact several fields including human-centered cyber-physical systems, cyber-security, mobile communications, bioinformatics and applications that require high performance and energy efficient embedded computing from different sensors. The proposed benchmark, characterization, and software-hardware computing framework will be freely shared and broadly disseminated among colleagues in related disciplines. Research results will be integrated in graduate and undergraduate courses offered by the investigators in both campuses. The PIs are active in several campus-wide and national organizations that work to attract and retain members of under-represented groups to engage in research and complete graduate degrees in science and engineering.

随着小型、低成本可穿戴计算技术的快速发展，开发能够持续警惕地监测生理信号的个人健康监测设备有巨大的机会。可穿戴生物医学设备有可能通过早期干预和防止昂贵的住院治疗来降低与许多慢性疾病相关的发病率、死亡率和经济成本。这些低功耗系统需要能够快速、准确地处理和解释大量数据，并仅在有保证时才生成智能警报。该项目的目标是构建下一代异构生物医学信号处理平台的基础，该平台可以满足当前和未来一代的能效要求和计算需求。 PI 首先了解现成嵌入式低功耗多核 CPU、GPU 和 FPGA 平台上新兴生物医学信号和成像应用的具体特征，以准确了解它们提供的权衡和瓶颈。基于这些结果，PI 将在硬件中设计和构建特定领域的众核加速器，并将其与现成的嵌入式处理器集成，这些处理器结合了这些应用的性能、可扩展性、可编程性和功效要求。 PI 将在硬件中实现拟议的异构架构，并通过许多现实生物医学工作负载（包括癫痫检测、手持式超声频谱多普勒和成像、舌头驱动辅助装置和假肢手控制接口）评估其性能和功效。跨学科研究工作可以激发和实现医疗保健监测的新方法，并可以对多个领域产生重大影响，包括以人为中心的网络物理系统、网络安全、移动通信、生物信息学以及需要来自不同传感器的高性能和节能嵌入式计算的应用程序。所提出的基准、表征和软硬件计算框架将在相关学科的同事之间自由共享和广泛传播。 研究成果将纳入两个校区的研究人员提供的研究生和本科生课程中。 PI 积极参与多个校园范围内和全国性的组织，致力于吸引和留住代表性不足群体的成员，从事研究并完成科学和工程领域的研究生学位。
