The heart of SiFive is RISC-V, the ISA invented by SiFive’s founders 5 years prior to starting the company! SiFive is evolving the building blocks of RISC-V-based IP that are reimagining and democratizing every computing platform. In technology, evolution is not merely a timeline of random changes. It is a well-planned ladder of interdependent milestones. Each step creates a new set of environmental conditions that make the next, more complex, leap inevitable. Winning requires flexibility and innovation to adapt. Both are core values of SiFive and RISC-V.

RISC-V is maturing fast, and the P570 Gen 3 is proof — here's what that means for the developers and system designers who've been waiting for it.

我们自信地宣布公司发展历程中最重要的里程碑之一：完成 **4 亿美元** 的融资。本轮融资由 Atreides Management 领投，其他顶级投资机构\*包括 Apollo Global Management、NVIDIA（英伟达）、Point72 Turion 和 T. Rowe Price Investment Management, Inc.，以及现有投资者 Prosperity7 Ventures 和 Sutter Hill Ventures 参投。此次融资使公司估值达到 **36.5 亿美元**，并将加速 SiFive 的 RISC-V CPU 及 AI IP 解决方案推向数据中心和 AI 基础设施市场的核心地带。

RISC-V 指令集架构 (ISA) 在设计上兼顾简洁与模块化。为了实现上述设计目标，RISC-V 有意识地减少了寻址方式的种类，从而降低了实现复杂 ISA 时的一项重大成本。寻址方式成本高昂：在小型设计中，会增加解码开销；在大型设计中，则会引入隐式依赖成本。
