icyflex-V, a New Ultra-low-power Processor based on RISC-V Architecture

Abstract

The icyflex-V processor is a new ultra-low-power core based on the RISC-V 32-bit ISA, a long-awaited addition to the CSEM icyflex processor family, compatible with off-the-shelf open-source and/or proprietary programming tools. This new development represents a cost effective yet performing alternative to proprietary cores for next-generation ultra-low-power system-on-chip developments. The core was optimized for performance, code density and power consumption and delivers up to 3.2 CoreMark/MHz while consuming as low as 14 uA/MHz in TSMC 55 nm low-power process.
