StarFive Dubhe 64-bit RISC-V core to be found in 12nm, 2 GHz processors

StarFive Dubhe RISC-V Core

StarFive has just announced customers’ delivery of the 64-bit RISC-V Dubhe core based on RV64GC ISA plus bit manipulation, user-level interrupts, as well as the latest Vector 1.0 (V) and Hypervisor (H) instructions. StarFive Dubhe can be clocked up to 2 GHz on a 12nm TSMC process node, and the company also released performance numbers with a SPECint2006 score of 8.9/GHz, a Dhrystone score of 6.6 DMIPS/MHz, and a CoreMark score of 7.6/MHz. A third-party source told CNX Software it should be equivalent to the SiFive Performance P550 RISC-V core announced last summer, itself comparable to Cortex-A75. StarFive Dubhe highlights: Typical frequency – 2.0 GHz @ TSMC 12nm “Industry-leading” Power and Area Efficiency (TSMC 12nm) RISC-V Vector Extension Data types: floating point, fixed point and integer VLEN=128-1024bits ALU & data path width=128 or 256 bits Full vector register grouping (LMUL) support RISC-V Virtualization Extension Pre-integrated Multi-Core with Memory Coherency Support […]

Imagination introduces Catapult RISC-V CPU cores

Catapult RISC-V CPU

As expected, Imagination Technologies is giving another try to the CPU IP market with the Catapult RISC-V CPU cores following their previous unsuccessful attempt with the MIPS architecture, notably the Aptiv family. Catapult RISC-V CPUs are/will be available in four distinct families for dynamic microcontrollers, real-time embedded CPUs, high-performance application CPUs, and functionally safe automotive CPUs. The new 32-/64-bit RISC-V cores will be scalable to up to eight asymmetric coherent cores-per cluster, offer a “plethora of customer configurable options”, and support optional custom accelerators. What you won’t see today are block diagrams and detailed technical information about the cores because apparently, all that information is confidential even though some Catapult RISC-V cores are already shipping “in high-performance Imagination automotive GPUs”. The only way to get more details today is to sign an NDA. Having said that we have some more information about the target markets and development tools.  Imagination Capapult […]

Hardware security flaw impacts Intel Apollo Lake & Gemini Lake processors

Hardware security flaw intel-atom, celeron, pentium Apollo Lake, Gemini Lake

A few years go the Spectre and Meltdown hardware security vulnerabilities impacted a wide range of processors from Intel, AMD, Arm, and others. But a newly discovered hardware security flaw impacts specifically the Atom, Celeron, and Pentium from the Apollo Lake, Gemini Lake, Denverton … low-power processors we often feature on CNX Software. Researchers have managed to activate test or debug logic at runtime for some low-power Intel processors, which they could use to escalate privilege, retrieve the “fuse encryption key” aka “chipset key fuse” unique to each processor, and access encrypted data. Most people do not need to panic though, as the hack would require physical access to the machine, and Intel says it is releasing firmware updates to mitigate the vulnerability. High-value targets should care though as the hack only takes 10 minutes, and if a laptop is stolen or lost, a skilled attacker should be able to […]
