论文摘要
用于小数计算的软件硬件共同设计解决方案可以在硬件成本和性能方面为嵌入式系统的开发提供多个帕累托点。本文演示了如何使用RISC-V生态系统准确评估此类共设计解决方案。在软件硬件共同设计解决方案中，解决方案的一部分需要专用的硬件。在我们的评估框架中，我们开发了由加速器支持的新的小数为导向的说明。该框架可以实现性能的周期准确分析以及用于小数计算的共同设计解决方案的硬件开销。将获得的性能结果与带虚拟函数的估计进行了比较。
Software-hardware co-design solutions for decimal computation can provide several Pareto points to development of embedded systems in terms of hardware cost and performance. This paper demonstrates how to accurately evaluate such co-design solutions using RISC-V ecosystem. In a software-hardware co-design solution, a part of solution requires dedicated hardware. In our evaluation framework, we develop new decimal oriented instructions supported by an accelerator. The framework can realize cycle-accurate analysis for performance as well as hardware overhead for co-design solutions for decimal computation. The obtained performance result is compared with an estimation with dummy functions.
