The article discusses the creation of a RISC-V emulator in Rust, detailing the hardware components and instruction sets needed for running xv6, a Unix-like OS. The book covers topics such as ISA, privileged architecture, exceptions, interrupts, peripheral devices, and virtual memory systems. The source code for the project is available on GitHub. By following the guide and implementing the emulator, readers will be able to run xv6 in their emulators. The author, @d0iasm, welcomes feedback and questions via Twitter or GitHub.

AI agent designs a complete RISC-V CPU from a 219-word spec sheet in just 12 hours — comparably simple design required 'many tens of billions of tokens'

Verkor.io's AI system, Design Conductor, autonomously designed a complete RISC-V CPU core from a 219-word spec sheet in just 12 hours, a significantly faster timeline compared to traditional chip design processes. The resulting processor, VerCore, is a five-stage pipelined core that achieved a CoreMark score of 3,261. While the system showed impressive capabilities, it still requires human experts to guide it towards a production-ready chip, and the compute requirements increase non-linearly with design complexity. Verkor plans to release VerCore's RTL source and build scripts soon and showcase an FPGA implementation at the Electronic Design Automation Conference.

Microsoft facing $2.8 billion UK lawsuit for overcharging 60,000 businesses using Microsoft Server on other clouds — Azure users allegedly received lower wholesale pricing

Microsoft is facing a $2.8 billion lawsuit in the UK for allegedly overcharging 60,000 businesses using Microsoft Server on non-Microsoft clouds, leading to Azure users receiving lower wholesale pricing. The UK Competition Appeals Tribunal certified the case, which is proceeding to trial despite Microsoft's appeal. This legal trouble is in addition to another ongoing appeal regarding reselling perpetual licenses. Regulators in the US and Europe are also investigating Microsoft and other cloud computing firms for potential antitrust violations.

Emulation-based SoC Security Verification (U. of Florida)

Emulation-based SoC Security Verification (U. of Florida)

Researchers at the University of Florida have published a technical paper titled "Emulation-based System-on-Chip Security Verification: Challenges and Opportunities," focusing on the importance of security validation in semiconductor design due to increasing system-on-chip (SoC) complexity. The paper highlights hardware emulation as a crucial pre-silicon verification technology that allows for high-throughput execution of designs under realistic conditions for security analysis. It covers various aspects of emulation-based security verification workflows, including instrumentation, stimulus generation, and runtime monitoring. The paper also discusses emerging trends like AI-assisted emulation and automated vulnerability assessment, positioning emulation as a key element in ensuring hardware security.
