The poster and slides from Chaoqun's @chaoqun_L #DATE2025 contribution "Towards Reliable Systems: A Scalable Approach to AXI4 Transaction Monitoring" are now online. Check them out: pulp-platform.org/docs/date2025/… & pulp-platform.org/docs/date2025/…

We propose a method to accelerate the Softmax function, a key bottleneck in Transformer models, by integrating a custom exponential instruction into Snitch. See "VEXP: A Low-Cost RISC-V ISA Extension for Accelerated Softmax Computation in Transformers" arxiv.org/pdf/2504.11227

Addressing the softmax bottleneck in @pulp_platform clusters, at a minimum hardware cost. This is critical for efficient attention computation, especially when GEMM/V is accelerated by the redmule tensor engine!

Check out our CF25 paper "CVA6-VMRT: A Modular Approach Towards Time-Predictable Virtual Memory in a 64-bit Application Class RISC-V Processor" a CVA6 extended with HW support for predictability in virtual memory access with minimal area overhead arxiv.org/pdf/2504.05718

Here is our latest a brief on a 16nm, reliable, time-predictable heterogeneous SoC with multiple programmable accelerators. See now "A Reliable, Time-Predictable Heterogeneous SoC for AI-Enhanced Mixed-Criticality Edge applications" on arXiv: arxiv.org/pdf/2502.18953 @Ang_93

We present a lightweight, modular, technology-independent & open-source real-time extension to AXI4 interconnect. See "AXI-REALM: Safe, Modular and Lightweight Traffic Monitoring and Regulation for Heterogeneous Mixed-Criticality Systems" arxiv.org/pdf/2501.10161 @ThommyThomaso

Next for #DATE2025 in Lyon, @chaoqun_L will present a versatile Transaction Monitoring Unit for AXI4-based SoCs. Find the paper on arXiv under "Towards Reliable Systems: A Scalable Approach to AXI4 Transaction Monitoring" arxiv.org/pdf/2501.17605 @ThommyThomaso @aottaviano96

Practical, open-source AXI4 standard IPs for real-time on-chip communication! Specifically targeting mixed-criticality SoC for automotive, satellites, robots...

Just before the end of the year, here is our paper "Open-Source Heterogeneous SoCs for AI: The PULP Platform Experience" with focus on designing heterogeneous AI acceleration SoCs. Find it here: arxiv.org/pdf/2412.20391 @arunax @Ang__93 @duav_red @GiuseppeTag

We present "A Flexible Template for Edge Generative AI with High-Accuracy Accelerated Softmax & GELU" based on a 8-core RISC-V cluster with a 24 × 8-PEs tensor processing unit and a novel accelerator for BFloat16 softmax. See arxiv.org/pdf/2412.06321 @YvanTortorella @Ang__93

We have recently taped out ASTRAL, a flexible, high-performance, secure & reliable heterogeneous SoC based on PULP, targeting space applications🚀. Learn more: asic.ethz.ch/2024/Astral.ht… #RISCV @YvanTortorella @CianiMaicol @MikeRogenmoser @chaoqun_L @Ang__93 @arunax

Tadaa! Carfield has just printed its first hello world string. Thanks to DUTCTL presented at #RISCV summit and the amazing work on standardizing Cheshire, we could bring Carfield up in less than 4 hours! pulp-platform.org/docs/riscvmuni… asic.ethz.ch/2023/Carfield.… @ThommyThomaso

The second Open-Source Hardware Workshop at #CF24 has just finished in Italy, what an great event!! Our @DavideSchiavo10 was co-charing the event with @ETH @pulp_platform and Uni Bologna and Poly Torino. Great talks also including our #OpenHW #CVA6 🤩 #semiconductor #opensource

OSHW24 collocated with CF'24 takes place next week. We will be there with Gigabit, DMA-enhanced Open-Source Ethernet Controller for Mixed-Criticality Systems @chaoqun_L & NARS: Neuromorphic Acceleration through Register-Streaming Extensions on RISC-V Cores #Workshop:%20Open-Source%20Hardware%20Workshop%20(OSHW24)" target="_blank" rel="nofollow noopener">computingfrontiers.org/2024/program.h…

Nice opportunity to submit a paper! @LucaBeniniZhFe, @duav_red & @Ang__93 are organizing SSH-SoC collocated with #DAC2024. @JBalkind, John East, Jon Michelson @zeroRISCinc, Jose Martins #UMinho & Rafail Psiakis @TIIuae among invited speakers. Learn more: ssh-soc-workshop.github.io/2024/.

Save the dates for CF24-OSHW Workshop on Open-Source Hardware May 7th - 9th, 2024 in Ischia that we are co-organizing together with @openhwgroup, Uni Bologna and Polytechnic of Torino. Read all about it here: cfwosh2024.github.io

We are thrilled to announce that Jon Michelson, VP of Engineering and co-founder of zeroRISC, will be delivering a talk at the upcoming second edition of the Safety and Security in Heterogeneous Open System-on-Chip Platforms (SSH-SoC) Workshop.

Opportunity for paper submission at the Safety and Security in Heterogeneous Open System-on-Chip Platforms Workshop All the details here: ssh-soc-workshop.github.io/2024/ #opensource #riscv #security #safety #heterogeneous #soc @openhwgroup @pulp_platform @epflecocloud

Our congratulations to Angelo @Ang__93 who just won the ISSCC 2023 Outstanding Forum Presenter Award for his last year's contribution "Is an AI Accelerator All You Need?". Check out the talk pulp-platform.org/docs/isscc2023…

We are delighted to release Carfield, our open-research heterogeneous platform for safety, resilient & time-predictable systems. It now comes with exhaustive docs & an end-to-end getting started guide for tests & apps. Give it a try pulp-platform.github.io/carfield/ github.com/pulp-platform/…
