ISSCC低功耗数字电路WiMAX并行处理
▸超低电压系统设计:通过并行处理架构(如CABAC块)和算法优化,实现在超低电压下的高吞吐量,显著降低功耗,适用于下一代视频标准HEVC。技术贡献包括联合架构与算法优化,达到行业领先水平。
▸新型低电压逻辑库:采用超级流水线和并行化技术(如FFT实现),通过增加流水线级数降低泄漏/动态功耗比,提升性能和能源效率。创新点在于全功能单元利用率优化,比传统超低电压设计更高效。
▸WiMAX芯片先进成果:在0.6V超低电压下实现DSP操作,克服28nm先进工艺中局部晶体管阈值变化挑战。技术贡献包括低电压稳定性设计和抗工艺变异电路技术,适用于深亚微米节点。
▸能效优化数字系统:通过多篇论文展示系统级创新,如并行化架构、流水线深度优化及低电压逻辑库设计,综合提升能效比(具体指标见各论文),为低功耗集成电路提供新范式。
Abstract
ational Solid-State Circuits Conference
(ISSCC) is the foremost global forum for presenting
advances in solid-state circuits and systems-on-a-chip. Every
year since its first issue, the IEEE J OURNAL OF SOLID-STATE
CIRCUITS has highlighted some well-received papers from the
most recent ISSCC in special issu es. This special issue covers
the ISSCC conference held in San Francisco, CA, February
20–24, 2011. Session chairs an d co-chairs initially recom-
mended papers for publication, with final deci
