Abstract

Many functions of embedded systems are implemented by software for flexibly dealing with frequent upgrade and for quickly fixing unpredictable bugs in applications. This system architecture is however generally less energy efficient than that implemented by application specific hardware. As a remedy of this issue, this paper proposes a processor-based platform having an RTOS in hardware for energy efficient and flexible TCP/IP processing. Unlike application specific hardware, implementing RTOS in hardware does not lose the fl exibility of the applications while the energy efficiency is comparable to the application specifi c hardware. Experiments with an actual TCP/IP application demonstrate that our approach achieves a 7 times improvement in energy effi ciency over an existing commercial fi rmware RTOS.
基于软件的高效TCP/IP处理的硬件RTOS
嵌入式系统的许多功能都是通过软件实现的,可以灵活地处理频繁的升级和快速修复应用程序中不可预测的错误。然而,这种系统体系结构通常不如由特定于应用程序的硬件实现的体系结构节能。为了解决这个问题,本文提出了一种基于处理器的平台,该平台在硬件上具有RTOS,用于节能和灵活的TCP/IP处理。与特定于应用程序的硬件不同,在硬件中实现RTOS不会失去应用程序的灵活性,而能源效率与特定于应用程序的硬件相当。实际TCP/IP应用的实验表明,我们的方法在能源效率方面比现有的商业固件RTOS提高了7倍。
