Energy Micro touts power-saving ARM RTOS

12 June 2013 Design Automation

Microcontroller maker Energy Micro announced the immediate availability of the Keil RTX real-time operating system (RTOS) as part of its Simplicity Studio tool suite. The RTOS, which has been optimised for ARM Cortex-M processors to provide flexible scheduling and high-speed operation, has been extended by Energy Micro to enable an ultra-low power, deep-sleep mode between tasks.

Energy Micro has implemented an extension to the ARM Keil RTX that is referred to as a ‘tickless’ mode and which allows the EFM32 MCU to wake up only when needed, either at a scheduled time or on an interrupt event. This results in significantly better current consumption than competing solutions based on using the system timer, which requires a constantly running high-frequency clock. With RTX RTOS, EFM32 users can now enter a deep sleep mode, consuming less than 1 μA, between normal active operations.

Keil RTX is provided with full source code under a BSD licence that is free of charge for everyone, including for commercial usage. For easy portability, Keil RTX implements the RTOS API of the ARM Cortex Microcontroller Software Interface Standard (CMSIS). It is available for all of Energy Micro’s EFM32 MCU families via the Simplicity Studio software suite.

Simplicity Studio is a free and complete tools suite providing instant access to Energy Micro’s latest datasheets, application notes, software tools, third-party IDE, code examples, demos and other EFM32 Gecko resources.
