RISC-V’s Increasing Influence
By Brian Bailey - 12 Jun, 2025 - Comments: 0

The industry is increasingly talking about benefits brought by the RISC-V architecture, but is it even the right starting point? While it may not be perfect, it may provide the flexibility necessary to move forward gradually. Computer architectures and software have followed in the footsteps of processors developed 80 years ago. They aimed to solve sequential, scalar arithmetic problems usin... » read more

Trapped By Legacy
By Steve Roddy - 15 May, 2025 - Comments: 0

At Quadric, we do a lot of first-time introductory visits with prospective new customers. As a rapidly expanding processor IP licensing company that is starting to get noticed (even winning IP Product of the Year!) such meetings are part of the territory. Which means we hear a lot of similar-sounding questions from appropriately skeptical listeners who hear our story for the very first time. Th... » read more

Increasing Design Flexibility With RISC-V-Based Processor IP
By Rich Collins - 21 Oct, 2024 - Comments: 0

The semiconductor industry increasingly needs more flexible and scalable processor architectures, driving the growing adoption of RISC-V. Originally developed at the University of California, Berkeley, the open-source RISC-V instruction set architecture (ISA) has become very popular in recent years. RISC-V allows designers to customize their processor implementations to meet the specific needs ... » read more

CPU Performance Bottlenecks Limit Parallel Processing Speedups
By Bryon Moyer - 12 Aug, 2024 - Comments: 0

Multi-core processors theoretically can run many threads of code in parallel, but some categories of operation currently bog down attempts to raise overall performance by parallelizing computing. Is it time to have accelerators for running highly parallel code? Standard processors have many CPUs, so it follows that cache coherency and synchronization can involve thousands of cycles of low-le... » read more

Top500: Frontier Still On Top, Sunway Formally Reappears
By Barry Pangrle - 05 Jan, 2024 - Comments: 0

New versions of the Top500 and Green500 lists have been released, and Frontier continues its reign at Number. 1. But a newcomer, Aurora, using Intel’s Sapphire Rapids, has entered at the Number 2 position with a “half-scale” system. Both machines are HPE Crays, with the former using AMD optimized third-gen EPYC 64C at 2.0GHz and AMD Instinct MI250X, while the latter uses Intel Xeon CPU... » read more

Verifying A RISC-V Processor
By Ed Sperling - 17 Oct, 2023 - Comments: 0

Verifying an SoC is very different than verifying a processor due to the huge state space in the processor. In addition to the tools needed for an SoC, additional tools are required for a step and compare environment. Larry Lapides, vice president at Imperas, talks about the need to verify asynchronous events like interrupts, how to compare a reference model to RTL, and the need for both hardwa... » read more

RISC-V Wants All Your Cores
By Brian Bailey - 12 Oct, 2023 - Comments: 0

RISC-V is no longer content to disrupt the CPU industry. It is waging war against every type of processor integrated into an SoC or advanced package, an ambitious plan that will face stiff competition from entrenched players with deep-pocketed R&D operations and their well-constructed ecosystems. When Calista Redmond, CEO for RISC-V International, said at last year's summit that RISC-V w... » read more

Specialization Vs. Generalization In Processors
By Brian Bailey - 10 Aug, 2023 - Comments: 1

Academia has been looking at specialization for many years, but solutions were rejected because general-purpose solutions were advancing fast enough to keep up with most application requirements. That is no longer the case. The introduction and support of the RISC-V processor architecture has attracted a lot of attention, but whether that is the right direction for the majority of modern comput... » read more

Advanced RISC-V Verification Methodology Projects
By Imperas - 24 May, 2023 - Comments: 0

The open standard of RISC-V offers developers new freedoms to explore new design flexibilities and enable innovations with optimized processors. As a design moves from concept to implementation new resources are appearing to help with standards for testbenches, verification IP reuse, and coverage analysis. RISC-V offers every SoC team the possibility to design an optimized processor, but this a... » read more
