摘要

一个7.07 mm2的可合成流处理单元(SPU)在65纳米的CMOS技术与8级铜层制造。它从最初的定制设计迁移到可合成设计,以获得更高的设计可移植性。新功能是新的平面图,高度优化的标准单元库,本地时钟生成器克隆和自适应线宽控制。在相同的过程生成中,它的逻辑面积比完全定制设计的SPU小30%。正确的功能操作是在1.4 V的4ghz下实现的。

A Design Methodology Realizing an Over GHz Synthesizable Streaming Processing Unit
A 7.07 mm2 synthesizable streaming processing unit (SPU) is fabricated in a 65 nm CMOS technology with 8 level copper layers. It is migrated from its original custom design to a synthesizable design to get higher design portability. New features are a new floor plan, height optimized standard cell library, local clock generator cloning and adaptive wire width control. Its logic area is 30% smaller than the full custom designed SPU in the same process generation. Correct functional operation is realized in 4 GHz at 1.4 V.
