A 12nm Linux-SMP-Capable RISC-V SoC with 14 Accelerator

📋 论文概要

该论文介绍了一款基于12nm工艺的RISC-V SoC，支持Linux对称多处理（SMP），并集成了14个加速器。通过分布式硬件电源管理和灵活的基于NoC的数据编排，解决了多核异构SoC的功耗与数据通信效率问题。

💡 主要创新点

• 在12nm工艺下实现了支持Linux SMP的RISC-V多核SoC，具备完整的操作系统兼容性。
• 集成了14个专用加速器，并通过分布式硬件电源管理实现动态功耗优化。
• 采用灵活的基于NoC的数据编排架构，提升多加速器间的数据通信效率与可扩展性。

This brings challenges in managing how the accelerators access shared resources, e.g., the memory hierarchy,
