SiFive Performance P870

P870 核心非常适合高性能消费性应用，或与数据中心的矢量处理器结合使用，在指令集架构的可用性、吞吐量、并行性和内存带宽方面，树立了令人印象深刻的全新 RISC- V 性能标准。P870 是一个六宽乱序核心，与上一代 SiFive Performance 系列处理器相比，峰值单线程性能提升了 50% (specINT2k6)，符合 RVA23 要求，并提供共享集群缓存，支援高达 32 核集群。高执行吞吐量，可在每个周期达到执行更多指令、做更多算术逻辑运算、或执行更多分支操作。P870 完全兼容于 Google 对 RISC-V 上 Android 的平台要求。P870 更提供其他已经过验证的 SiFive 功能：

· 128b VLEN 长度的RISC-V矢量 (RVV)

· 矢量加密和 Hypervisor 扩展

· IOMMU 和先进中断架构 (AIA)

· 非包含性 (non-inclusive) 三级缓存

SiFive Intelligence X390

广受欢迎的 SiFive Intelligence X280 于 AI/ML 应用与移动、基础设施和汽车应用中的硬件加速器相结合方面取得了成功。新的 X390 凭借其单核配置、双倍矢量长度和双矢量 ALU，将矢量运算性能提高了 4 倍，这也使得持续数据带宽增加了 4 倍。借助 SiFive 矢量协处理器接口扩展 (VCIX)，您可以轻松添加自己的矢量指令和/或加速硬件设计，带来前所未有的设计灵活度，也能让用户透过自定义指令大幅提高性能。产品特点包括：

· 1024位VLEN、512位DLEN

· 单/双矢量ALU

· VCIX (2048 bits 输出，1024 bits 输入)

适用于生成式 AI 应用的敏捷硬件解决方案

将采用 P870 的高性能通用运算 SoC，与由 X390 和客户 AI 硬件引擎组成的高性能 NPU 集群结合在一起，为产品设计人员提供高度灵活、低功耗和可编程的解决方案，并为复杂工作负载提供卓越的计算密度。

SiFive 特别提到人们对这些可组合 SiFive 解决方案的浓厚兴趣，许多客户使用高性能产品取得了芯片成功并进入商业化的各个阶段。

SiFive 也将持续在整个生态系中与合作伙伴积极合作，随着客户将产品商业化的进程，与这些合作伙伴共同确保基于 SiFive 处理器设计的产品，能够享受到开放标准生态系的软件、安全性和灵活度优势。
