Zusammenfassung:This paper is an extension of Hu et al., ISSCC, 2013, and it introduces the 32/28 nm implementations of Godson-3B1500, which are 8-core MIPS-compatible microprocessors with vector extensions. Godson-3B1500 is fabricated in STMicroelectronics 32/28 nm high-κ metal-gate low-power bulk CMOS with 10 metal layers. It contains 1.14 billion transistors and operates at the frequency of 1.0 GHz to 1.5 GHz with the voltage supply ranging from 1.0 V to 1.3 V. Compared to its predecessor (Hu et al., ISSCC, 2011), Godson-3B1500 brings significant power efficiency improvements with enhanced performance (150GFLOPS@1.2 GHz) and reduced power dissipation (
