Forskning
BISMO: A Scalable Bit-Serial Matrix Multiplication Overlay for Reconfigurable Computing
BISMO is a programmable FPGA accelerator for low-precision integer matrix multiplication. It offers high-performance matrix multiplication, which is beneficial for applications like quantized neural network inference and approximate computing approaches.
SOCRATES: Self-Organizing Computational substRATES
SOCRATES (Self-Organizing Computational substRATES) is a long-term time horizon project seeking radical breakthroughs toward efficient and powerful data analysis available everywhere, from the simplest sensor node to the most complex supercomputer.
SpinENGINE: Harnessing the Emergent Properties of Nanomagnet Ensembles for Massively Parallel Data Analysis
The SpinENGINE project will lay the foundations for a new, massively parallel, platform based on emergent behavior in nanomagnet ensembles.
BOWI: Boosting Widening Digital Innovation Hubs
BOWI project – connecting digital innovation hubs and SMEs in the discovery of advanced digital solutions.
Power Management for LTE base stations
The LTE Uplink Receiver PHY benchmark is a realistic implementation of the baseband processing for an LTE mobile base station. The benchmark implements the processing required by the base station in an uplink.
Twin-Precision Multipliers
This multiplier generator is capable of generating several kinds of multipliers that all have been based on the regular reduction tree of the High Performance Multiplier.
FlexSoC
The FlexSoC program, launched during 2003, aims to develop new architectural techniques for the complex processors necessary for high-performance embedded systems.
JLM: A research compiler based on the RVSDG IR
Jlm is an experimental compiler/optimizer that consumes and produces LLVM IR. It uses the Regionalized Value State Dependence Graph (RVSDG) as intermediate representation for optimizations.
SPrINTER
The SPrINTER project will create the foundation of a radically new technology for batteryless intermittent computing devices required for a sustainable digital society.
PERSEUS
PERSEUS aims to educate top-level researchers contributing to solve societal challenges within the areas of energy, healthcare, manufacturing, mobility, and ocean-based technology, through the use of digital technologies.
