Sparse Stream Semantic Registers: A Lightweight ISA Extension Accelerating General Sparse Linear Algebra
Paul Scheffler, Florian Zaruba, Fabian Schuiki +2
Sparse linear algebra is crucial in many application domains, but challenging to handle efficiently in both software and hardware, with one- and two-sided operand sparsity handled…
Indirection Stream Semantic Register Architecture for Efficient Sparse-Dense Linear Algebra
Paul Scheffler, Florian Zaruba, Fabian Schuiki +2
Sparse-dense linear algebra is crucial in many domains, but challenging to handle efficiently on CPUs, GPUs, and accelerators alike; multiplications with sparse formats like CSR an…
An Open-Source Platform for High-Performance Non-Coherent On-Chip Communication
Andreas Kurth, Wolfgang Rönninger, Thomas Benz +4
On-chip communication infrastructure is a central component of modern systems-on-chip (SoCs), and it continues to gain importance as the number of cores, the heterogeneity of compo…
Manticore: A 4096-core RISC-V Chiplet Architecture for Ultra-efficient Floating-point Computing
Florian Zaruba, Fabian Schuiki, Luca Benini
Data-parallel problems demand ever growing floating-point (FP) operations per second under tight area- and energy-efficiency constraints. In this work, we present Manticore, a gene…
FPnew: An Open-Source Multi-Format Floating-Point Unit Architecture for Energy-Proportional Transprecision Computing
Stefan Mach, Fabian Schuiki, Florian Zaruba +1
The slowdown of Moore's law and the power wall necessitates a shift towards finely tunable precision (a.k.a. transprecision) computing to reduce energy footprint. Hence, we need ci…
Snitch: A tiny Pseudo Dual-Issue Processor for Area and Energy Efficient Execution of Floating-Point Intensive Workloads
Florian Zaruba, Fabian Schuiki, Torsten Hoefler +1
Data-parallel applications, such as data analytics, machine learning, and scientific computing, are placing an ever-growing demand on floating-point operations per second on emergi…
Stream Semantic Registers: A Lightweight RISC-V ISA Extension Achieving Full Compute Utilization in Single-Issue Cores
Fabian Schuiki, Florian Zaruba, Torsten Hoefler +1
Single-issue processor cores are very energy efficient but suffer from the von Neumann bottleneck, in that they must explicitly fetch and issue the loads/storse necessary to feed t…
Ara: A 1 GHz+ Scalable and Energy-Efficient RISC-V Vector Processor with Multi-Precision Floating Point Support in 22 nm FD-SOI
Matheus Cavalcante, Fabian Schuiki, Florian Zaruba +2
In this paper, we present Ara, a 64-bit vector processor based on the version 0.5 draft of RISC-V's vector extension, implemented in GlobalFoundries 22FDX FD-SOI technology. Ara's…
The Cost of Application-Class Processing: Energy and Performance Analysis of a Linux-ready 1.7GHz 64bit RISC-V Core in 22nm FDSOI Technology
Florian Zaruba, Luca Benini
The open-source RISC-V ISA is gaining traction, both in industry and academia. The ISA is designed to scale from micro-controllers to server-class processors. Furthermore, openness…
