RISC-V Heralds New Era Of Cooperation

By Brian Bailey - 30 May, 2024 - Comments: 0

RISC-V is paving the way for open source to become accepted within the hardware community, creating a level of industry collaboration never seen in the past, while revitalizing the connection between academia and industry. The big question is whether this arrangement is just a placeholder while the industry re-learns how to develop processors, or whether this processor architecture is someth... » read more

Coding And Debugging RISC-V

By Ann Mutschler - 06 Nov, 2023 - Comments: 0

As monolithic device scaling continues to wind down and evolve toward increasingly heterogeneous designs, it has created an inflection point for chip architects to create customized cores that are much more energy efficient and faster than off-the-shelf processors. Zdeněk Přikryl, CTO of Codasip, talks about where RISC-V fits into this picture, using a modular ISA and custom instruction layer... » 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

Why RISC-V Is Succeeding

By Brian Bailey - 24 Feb, 2022 - Comments: 5

There is no disputing the excitement surround the introduction of the RISC-V processor architecture. Yet while many have called it a harbinger of a much broader open-source hardware movement, the reasons behind its success are not obvious, and the implications for an expansion of more open-source cores is far from certain. “The adoption of RISC-V as the preferred architecture for many sili... » read more

Adding Value To Open-Source RISC-V Cores With Verification

By Lee Moore - 22 Apr, 2021 - Comments: 0

By Steve Richmond (Silicon Labs), Mike Thompson (OpenHW Group), and Lee Moore (Imperas Software) Modern SoC verification has matured to the point that some are suggesting the use of the word ‘prototype’ when referring to the first silicon samples is now unnecessary. This is due in part to the commercial EDA industry, which has provided the innovation and tools used throughout the design... » read more

Security Gaps In Open Source Hardware And AI

By Ed Sperling - 25 Nov, 2020 - Comments: 1

Semiconductor Engineering sat down to discuss security risks across multiple market segments with Helena Handschuh, security technologies fellow at Rambus; Mike Borza, principal security technologist for the Solutions Group at Synopsys; Steve Carlson, director of aerospace and defense solutions at Cadence; Alric Althoff, senior hardware security engineer at Tortuga Logic; and Joe Kiniry, princi... » read more

Open-Source Hardware Momentum Builds

By Brian Bailey - 25 Jun, 2020 - Comments: 2

Open-source hardware continues to gain ground, spearheaded by RISC-V — despite the fact that this processor technology is neither free nor simple to use. Nevertheless, the open-source hardware movement has established a solid foothold after multiple prior forays that yielded only limited success, even for processors. With demand for more customized hardware, and a growing field of startups... » read more

Open Source Hardware Risks

By Ann Mutschler - 08 Jan, 2020 - Comments: 0

Open-source hardware is gaining attention on a variety of fronts, from chiplets and the underlying infrastructure to the ecosystems required to support open-source and hybrid open-source and proprietary designs. Open-source development is hardly a new topic. It has proven to be a successful strategy in the Linux world, but far less so on the hardware side. That is beginning to change, fueled... » read more

Will Open-Source Processors Cause A Verification Shift?

By Ann Mutschler - 19 Dec, 2019 - Comments: 0

While the promised flexibility of open source could have advantages and possibilities for processors and SoCs, where does the industry stand on verification approaches and methodologies from here? Single-source ISAs of the past relied on general industry verification technologies and methodologies, but open-source ISA-based processor users and adopters will need to review the verification flows... » read more

Meltdown And Spectre, One Year Later

By Paul Kocher - 11 Feb, 2019 - Comments: 0

About this time last year, reports surfaced about security attacks on today’s most popular microprocessors (μPs). Researchers called them Meltdown, Spectre gaining widespread attention. Today, however, the industry and especially μP vendors have made some progress toward stemming these vulnerabilities. Here is my analysis as we enter into 2019. When it comes to these vulnerabilities, we ... » read more
