The VA10820 microcontroller was created to give designers a guaranteed rad-hard ARM Cortex-M0 that will operate reliably in space, at a fraction of the cost of an old-school space market FPGA.

SemiWiki's book PROTOTYPICAL: The Emergence of FPGA-Based Prototyping for SoC Design explores ARM’s role in FPGA prototyping technology. Read an excerpt here.

The ISC16 event occurred last week in Frankfurt, Germany. ISC stands for International Super-computing and while ARM is known for its energy-efficient, mobile CPU cores, we are beginning to make some waves…

This document demonstrates how to generate a library containing an assembly procedure that will be called through the Java Native Interface, within an Android project written in Java as an example. The…

Calling Java methods through native ARM assembly code, with an Android app and the JNI

The amount of data that consumers are producing is increasing at a phenomenal rate, and shows no signs of slowing down anytime soon. Cisco estimated last year that global mobile data traffic would multiply…

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.
