Architectures and Processors blog

Functional safety for Silicon IP used to be a niche activity, limited to an elite circle of chip and system developers in automotive, industrial, aerospace and similar markets. However over the last few…

The trend for the electronics industry remains the same as ever; we want chips that are smaller, faster, more efficient. When you look at the trajectory of SoC designs you can see that the cost of integrating…

One of the canards that’s regularly trotted out in discussions of ARM vs. x86 processors is the idea that ARM chips are intrinsically more power efficient thanks to fundamental differences in the ISA …

The end of the year is approaching, but I’d like to have one last delta before taking some time off. PowerPC vs. Arm, seems like an appropriate stand-off.

This blog focuses on some of the hardware innovations and changes that are relevant to shared virtual memory and cache coherency, which are components of the HSA hardware specification.

Consider this: The performance of smartphones, nearly all of which are powered by ARM processors, has grown by 100x since 2009. One hundred times in seven years! With that has emerged entirely new functionality…

By now you would have read the news about the latest ARM® Cortex®-A73 processor and Mali™-G71 GPU. These new processors allow for more performance in an ever thinner mobile device, and…

This is a paper published in Embedded World 2015, covering various areas about how chip designers can improve the reliability of a SoC (System-on-Chip) design. It also cover various functional safety…

Key benefits of Linux on ARM Complete scalable operating system providing a reliable multi-tasking environment Based on an open source model (GPL) Leverage a wide range of UNIX and open source applications…

This is a paper covering a introduction of AMBA 5 AHB5 and AMBA 4 Q channel (one of the protocols covered in the AMBA 4 Low Power Interface Specification). Abstract The on-chip system design of microcontrollers…

Abstract The next era of embedded products is demanding more from embedded processors. The breadth of chip solutions is growing as system designers demand higher integration and right-fit solutions. Security…

This White Paper is an introduction to porting existing code to the A64 instruction set supported by Armv8-A processors like the Cortex-A53 and Cortex-A57 from Arm.

The modern smartphone has long since ceased to be just a tool for calling other people. Nowadays we use it as a remote control for our world; recording our experiences first hand, entertainment devices…

Chinese Version（中文版）：ARM 的系统验证：让合作伙伴能够构建更好的系统 (Huge thanks to the system validation team in Bangalore for providing me with all of the technical information here. Much appreciated!)Functional validation…

This blog will cover the basics of interrupt latency, and what users need to be aware of when selecting a microcontroller with low interrupt latency requirements.

IntroductionIn ARM® Cortex®-A class CPUs, the Memory Management Unit (MMU) and Operating System (OS) work together to protect address spaces. A process running in unprivileged mode has its own virtual…

“It’s interesting to think you have something in your hands that you don’t quite understand.” You could apply that sentiment to inventions throughout history. You could apply that…

Overview of stack size requirement estimations in Arm Cortex-M based applications.

[note] This is an English translation edition of my article which appeared on the Interface magazine issued by the CQ publishing. I'm sorry for my poor English.[1] Background of the strongest Cortex-M4…

We’d like to welcome all of you and describe few interesting issues we encounter during our work with ARMv8 and FreeBSD. In this cycle it is planned to talk a little about various bugs found in the kernel…

We demand more of our phones than ever. These demands have to be possible within the constraints of the mobile form factor and its power limits. Achieving these goals without a premium price tag is a challenge…
