CHIP DESIGNER ARM has released a real-time architecture variant for embedded chips to boost the power of electronic devices and systems used in cars, hospitals and factories.

The architecture, dubbed ARMv8-R, will let companies make embedded chips that are faster and more power efficient, thus driving down costs.

ARM said that the main idea of the architecture is to support future automotive applications such as advanced driver assistance systems and vehicle to behicle communications, as well as factory automation applications and human-machine interfaces.

"For example, a microcontroller incorporating an ARMv8-R processor could host Linux for graphical management and networking functions together with real-time operating system workloads such as motor control," ARM explained.

ARMv8-R builds on the 32-bit ARMv7-R architecture used for the company's Cortex-R series of real-time processors.

"The ARMv8-R architecture specification will significantly enhance ARM's real-time 32-bit processor solutions with new features to expand their functionality and capability to meet for rapidly evolving market requirements."

ARM said the main feature of the architecture is a "bare metal" hypervisor mode. This lets programmers combine different operating systems, applications and real-time tasks on a single processor while at the same time keeping them isolated.

"[The] architecture will enable overall improvements in software quality and will support increasingly sophisticated embedded programming techniques such as model-based automated code generation," ARM added.

Further details of the ARMv8-R architecture will be disclosed at the ARM Techcon in Santa Clara next week. ARM processors that implement the new architecture are in development and details will be disclosed "at a later date", ARM said. µ
