With the advent of intelligent sensor nodes in everyday life, low power aspects of system design become more and more important. Adaptive body biasing is a promising methodology to achieve dynamic adaptation of the tradeoff between performance and energy b ...

Polar codes are a recently proposed class of block codes that provably achieve the capacity of various communication channels. They received a lot of attention as they can do so with low-complexity encoding and decoding algorithms, and they have an explici ...

We present an error correction code (ECC) decoder based on the Guessing Random Additive Noise Decoding (GRAND) with ABandonment (GRANDAB) algorithm for applications that require constant throughput and fixed decoding latency in the Gbps range. This high co ...

This paper presents DynOR, a 32-bit 6-stage OpenRISC microprocessor with dynamic clock adjustment. To alleviate the issue of unused dynamic timing margins, the clock period of the processor is adjusted on a cycle-by-cycle level, based on the instruction ty ...

Microcontroller systems operating at low supply voltage in near- or sub-threshold regime suffer both from increased effects of PVT (Process, Voltage, Temperature) variation and from a larger share of leakage on overall power due to the reduced frequency. W ...

In this work, we present eXtendible Heterogeneous Energy-Efficient Platform (X-HEEP), a configurable and extendible single-core RISC-V-based ultra-low-power microcontroller. X-HEEP can be used standalone as a low-cost microcontroller, or it can be integrat ...
