This work demonstrates a RISC-V vector microprocessor implemented in 28nm FDSOI with fully-integrated non-interleaved switched-capacitor DCDC (SC-DCDC) converters and adaptive clocking that generates four on-chip voltages between 0.5V and 1V using only 1.0V core and 1.8V IO voltage inputs. The design pushes the capabilities of dynamic voltage scaling by(More)
— Integrating multiple power converters on-chip improves energy efficiency of manycore architectures. Switched-capacitor (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(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)
—LDPC and turbo codes are channel codes commonly used for wireless communication. Decoding algorithms are computationally demanding, and so efficient implementations are often inflexible, targeting only the codes specified by a given standard. When support for multiple standards is needed, multiple decoders are generally used. We study the algorithms for(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)
