NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

随着 Arm 架构继续扩大其影响力 — 我们在本期雷达更新了对云上 Arm的评估 — 对更新但不那么成熟的 RISC-V 架构的兴趣也在增长。RISC-V 并没有在性能或效率方面带来突破 — 实际上,它的每瓦性能与 Arm 相似,且在绝对性能上无法与之竞争 — 但它是开源的、模块化的,且不依赖于单一公司。这使得它成为嵌入式系统中的一个有吸引力的选择,因为在这些系统中,架构的许可专有成本是一个重要的考虑因素。这也是为什么 RISC-V 用于嵌入式 领域日臻成熟,以及包括 SiFiveespressif 在内的几家公司正在为广泛的应用提供开发板和 SoCs。如今,能够运行 Linux 内核的微控制器和微处理器以及相应的软件栈和工具链都已可用。我们正在关注这一领域,并预计在未来几年内看到更多的采用。
