The purpose of this project is to explore novel embedded processor architectures for electronic textiles (e-textiles). E-textiles are intelligent fabrics where sensors and computation are intrinsic to the cloth, with applications in medicine, entertainment, and sports. E-textiles occupy an extremely constrained point in the embedded system design space, having a large number of networked sensors and processors distributed throughout the fabric and tight requirements on performance, energy consumption, and reliability.Research at the Virginia Tech E-textiles Lab has shown that a Model-Driven Engineering (MDE) approach allows designers to effectively manage the complexity of the e-textile design space, which includes issues such as fiber selection, the weave pattern, the physical topology of the electrical/communication network in the fabric, the number/type/location of sensor/actuator nodes, the number and type of computational nodes, the system software organization, and the application algorithms.However, an MDE approach does not yield an implementation that is easily portable while being power- and performance-efficient, due to a fundamental mismatch between the MDE design specification and the target microprocessors. The approach in this project is to develop an event-driven computer architecture family that presents an abstraction that is well-matched to the MDE design specification.The potential benefits of this project include using the architecture family to improve the reliability, design cost, and energy efficiency of embedded systems besides e-textiles. The broader impacts of the project include e-textile applications in medical monitoring, wearable computing, and pervasive computing. Educational benefits include providing undergraduate and graduate students with multidisciplinary research experience.

该项目的目的是探索用于电子纺织品（e-textiles）的新型嵌入式处理器架构。 电子纺织品是智能织物，其中传感器和计算是布料固有的，可应用于医学、娱乐和体育领域。 电子纺织品在嵌入式系统设计空间中占据着极其有限的位置，在整个织物中分布着大量的网络传感器和处理器，并且对性能、能耗和可靠性有着严格的要求。弗吉尼亚理工大学电子纺织品实验室的研究表明，模型驱动工程（MDE）方法使设计人员能够有效管理电子纺织品设计空间的复杂性，其中包括纤维选择、编织图案、 结构中电气/通信网络的物理拓扑、传感器/执行器节点的数量/类型/位置、计算节点的数量和类型、系统软件组织和应用算法。然而，由于 MDE 设计规范和目标微处理器之间的根本不匹配，MDE 方法无法产生易于移植、同时具有功率和性能效率的实现。 该项目的方法是开发一个事件驱动的计算机架构系列，它提供了与 MDE 设计规范完美匹配的抽象。该项目的潜在好处包括使用该架构系列来提高除电子纺织品之外的嵌入式系统的可靠性、设计成本和能源效率。 该项目更广泛的影响包括医疗监控、可穿戴计算和普适计算中的电子纺织品应用。 教育效益包括为本科生和研究生提供多学科研究经验。
