基于车载异构计算平台的SOA服务部署设计与实现

Design and Implementation of SOA Service Deployment Based on Vehicle Heterogeneous Computing Platform

针对异构SOC实时内核部署SOA服务的性能瓶颈,文章设计一种基于车载异构计算平台的SOA服务部署方法。实时内核从总线获取和提供原始数据,通过核间通信协议传输至性能内核,性能内核基于SOME/IP协议将原始数据封装为服务进行发布。与传统的直接在实时内核上发布SOME/IP服务的方式相比,该方法能显著降低实时内核系统的开销,有效解决实时内核运算力不足、无法支撑大量SOME/IP报文发送的问题。同时,由于性能内核具有强大的运算能力,后续服务可以灵活迭代与扩展,用户可以获得更加便捷的车控交互体验。

Aiming at the performance bottleneck of heterogeneous SOC real-time kernel deployment of SOA services,this paper designs an SOA service deployment method based on vehicle-mounted heterogeneous computing platform.The real-time kernel obtains and provides raw data from the bus,which is transmitted to the performance kernel through the Inter core Communication protocol,and the performance kernel encapsulates the raw data as a service for publication based on SOME/IP protocol.Compared with the traditional method of publishing SOME/IP services directly on the real-time kernel,this method can significantly reduce the overhead of the real-time kernel system,and effectively solve the problem that the real-time kernel has insufficient computing power and cannot support the sending of a large number of SOME/IP packets.At the same time,due to the strong computing capability of the performance core,the subsequent services can be flexibly iterated and expanded,and users can obtain a more convenient interactive experience of vehicle control.
