With the evolving complexity in automotive software in the last decade, a need for optimized custom hardware to support basic common functions is rising. AUTOSAR consortium defines a standard software specification for automotive software. A so-called SOME/IP (Scalable service-Oriented MiddlewarE over IP) transformer is one of these defined standard specifications. SOME/IP transformer is widely used in Ethernet-connected AUTOSAR-based Electronic Control Units for its scalability that is needed to cope with the increased optional features in today’s automotive software. In this paper, we propose a custom hardware support to accelerate one of the SOME/IP transformer functions, studying its overhead, limitations, and performance gain. Using our proposed solution, we achieved \(50\times \) speedup over of the traditional software implementation. The proposed hardware design maintains the same simplicity, flexibility, and modularity offered by traditional software solutions with minimal added overhead. Having a dedicated hardware for SOME/IP transformation makes the overall architecture more reliable.

随着汽车软件在过去十年中不断发展的复杂性，对优化定制硬件以支持基本通用功能的需求正在上升。AUTOSAR 联盟为汽车软件定义了标准软件规范。所谓的 SOME/IP（Scalable service-Oriented MiddlewarE over IP）转换器是这些定义的标准规范之一。SOME/IP 转换器广泛用于以太网连接的基于 AUTOSAR 的电子控制单元，因为它具有可扩展性，可以应对当今汽车软件中增加的可选功能。在本文中，我们提出了一种自定义硬件支持来加速其中一个 SOME/IP 转换器功能，研究其开销、限制和性能增益。使用我们提出的解决方案，我们实现了\(50\times \)加速传统软件实施。所提出的硬件设计保持了传统软件解决方案所提供的相同的简单性、灵活性和模块化，并且增加的开销最少。拥有专用于SOME/IP转换的硬件使得整体架构更加可靠。
