Arm A-Profile Architecture Developments 2023

As computing demands continue to evolve with the rise of artificial intelligence (AI) and advancing security threats, it is imperative that the foundational computing architecture at the heart of the world’s devices continues to evolve. This is why our engineering teams add new features and technologies to the pervasive Arm architecture, with the software teams then ensuring that software lan... » read more

RISC-V Customization Gets A Standing Ovation

Processor vendors have always tried to create a large software ecosystem around their products, because it creates stickiness and it naturally “locks-in” large numbers of customers who have invested in the creation of dedicated software. This effect is growing over time as the quantity of software is ever increasing per product: we could talk about more than 100 million lines of code in a c... » read more

The Uncertainties Of RISC-V Compliance

How far can a RISC-V design be pushed and still be compliant? The answer isn't always black-and-white because the RISC-V concept is very different from previous open-source projects. But as interest and activity in RISC-V continues to grow, constructive discussions are taking place to address some of the challenges of designing with an open-standard ISA. “The RISC-V standard is somethin... » read more

Capability Hardware Enhanced RISC Instructions (CHERI) For Verification, With Better Memory Safety (Oxford)

A technical paper titled "A Formal CHERI-C Semantics for Verification" was published by researchers at University of Oxford. Abstract: "CHERI-C extends the C programming language by adding hardware capabilities, ensuring a certain degree of memory safety while remaining efficient. Capabilities can also be employed for higher-level security measures, such as software compartmentalization, ... » read more

RISC-V Is Thriving: Here’s What You Need to Know

RISC-V, the open-standard Instruction Set Architecture (ISA) conceived by UC Berkeley developers in 2010, is going from strength to strength. The RISC in RISC-V stands for Reduced Instruction Set Computer, meaning it’s designed to simplify each individual instruction given to the computer. As RISC-V is an open standard, anyone can implement, customize, and expand the ISA to suit their r... » read more

5 Good Things About RISC-V

RISC-V has been around for some time now, and if you are here it’s because you have heard of it. But perhaps you still need to be convinced that it is the future? If you still wonder about its potential and benefits, here are five good things about RISC-V. 1. RISC-V is an open standard Let’s start simple. This is nothing new, but let’s be clear on what open standard means. Open stan... » read more

Implementing Cryptographic Algorithms for the RISC-V Instruction Set Architecture in Two Cases

This new technical paper titled "Symmetric Cryptography on RISC-V: Performance Evaluation of Standardized Algorithms" was published by researchers at Intel, North Arizona University and Google, with partial funding from U.S. Air Force Research Laboratory. Abstract "The ever-increasing need for securing computing systems using cryptographic algorithms is spurring interest in the efficient i... » read more

Customizing Processors

The design, verification, and implementation of a processor is the core competence of some companies, but others just want to whip up a small processor as quickly and cheaply as possible. What tools and options exist? Processors range from very small, simple cores that are deeply embedded into products to those operating at the highest possible clock speeds and throughputs in data centers. I... » read more

Big Changes In Embedded Software

Every good hardware or software design starts with a structured approach throughout the design cycle, but as chip architectures and applications begin focusing on specific domains and include some version of AI, that structure is becoming more difficult to define. Embedded software, which in the past was written for very narrow functions with a minimal footprint, is increasingly getting blended... » read more

Why RISC-V Is Succeeding

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
