40 nm, 1.1 V, 16-KB SRAM
能效性能电压调节ARM Cortex-M0SRAMIP重用
▸线程级处理器重构:通过动态调整处理器线程配置,实现在不同工作负载下的能效优化,相比传统电压调节技术提升1.8倍吞吐量(1.1V)并降低30%能耗(0.51V)。
▸行级内存重构:采用内存访问粒度动态调整技术,优化内存子系统能效比,减少无效能耗,在最低能量点实现1.3倍能耗降低。
▸架构无关的方法论:提出不依赖特定硬件架构的通用设计方法,支持第三方IP核(包括混淆/加密形式)的直接复用,仅需10.3%面积开销即可实现能效范围扩展。
▸即插即用式解决方案:通过标准化接口实现现有设计的无缝升级,保持原始软件栈兼容性,显著降低系统集成复杂度与设计成本。
Abstract
This work introduces reconfiguration for energy–
performance adaptation beyond conventional voltage scaling in
microcontroller-based systems. Coordinated thread-level proces-
sor and row-level memory reconfiguration are enabled by an
architecture-agnostic methodology. The latter requires low design
and integration effort while reusing existing macros, including
third-party intellectual properties (IPs) in an obfuscated or
encrypted form. The methodology represents a drop-in solution
that is applic
