A 45nm Single-Chip Application-and-Baseband Processor Using an Intermittent Operation Technique

📋 论文概要

本文提出一种采用间歇操作技术的45nm单芯片应用与基带处理器，实现在移动电话中兼顾高性能与低功耗的需求。通过动态调整操作周期，在重负载时提供高吞吐量，在轻负载时大幅降低功耗。

💡 主要创新点

• 提出间歇操作技术，允许处理器在微秒级时间尺度上动态切换活跃与休眠状态，从而按需调整性能与功耗。
• 将应用处理器和基带处理器集成在单芯片上，并采用45nm工艺实现，减小面积和成本。

On the other hand, mobile phones also demand low power consumption of the application processors for voice telephony, music player and light-load applications. Consequently, the chip for mobile phones must achieve appropriate power consumption for each application over a wide range of performance. Furthermore, because next generation mobile phones require more functions and higher performance than the current generation, it is important for the chip to both integrate various functions and to shrink the implementation area using the next process technology in order to reduce cost. Single-chip application-and-baseband processors [1, 2] currently exist in the mobile phone
