2015 Symposium on VLSI Circuits Digest of Technical Papers A RISC-V Vector Processor with Tightly-Integrated Switched-Capacitor DC-DC Converters in 28nm FDSOI Brian Zimmer1, Yunsup Lee1, Alberto Puggelli1, Jaehwa Kwak1, Ruzica Jevtic1, Ben Keller1, Stevo Bailey1, Milovan Blagojevic1,2, Pi-Feng Chiu1, Hanh-Phuc Le1, Po-Hung Chen1, Nicholas Sutardja1, Rimas(More)
Integrating multiple power converters on-chip improves energy efficiency of manycore architectures. Switchedcapacitor (SC) dc–dc converters are compatible with conventional CMOS processes, but traditional implementations suffer from limited conversion efficiency. We propose a dynamic voltage and frequency scaling scheme with SC converters that achieves high(More)
The ability of extracellular proteins to influence the regenerative process was examined in Sprague-Dawley rats. Silicon chambers, filled with sterile saline solutions of cytochrome-c, fibronectin, laminin, a combination of fibronectin and laminin, or nerve growth factor were surgically implanted between the severed ends of sciatic nerves to form gaps of 18(More)
The silicone chamber model was used to evaluate peripheral nerve regeneration (PNR) in streptozocin (STZ)-induced diabetic rats. Diabetic and control animals underwent sciatic nerve transection and silicone chamber implantation establishing gaps of various lengths between the transected nerve ends. In animals with 5 and 10 mm gaps, diabetes was induced in(More)
This work presents a RISC-V system-on-chip (SoC) with integrated voltage regulation and power management imple­ mented in 28nm FD-SOI. A fully integrated switched-capacitor DC-DC converter, coupled with an adaptive clocking system, achieves 82-89% system conversion efficiency across a wide operating range, yielding a total system efficiency of 41.8 double­(More)
The final phase of CMOS technology scaling provides continued increases in already vast transistor counts, but minimal improvements in energy efficiency, thus requiring innovation in circuits and architectures. However, even huge teams are struggling to complete large, complex designs on schedule using traditional rigid development flows. This article(More)
