Atmel teams with Segger on AVR32 OS

14 May 2008 DSP, Micros & Memory

Atmel and Segger Microcontroller, a leading manufacturer of middleware for embedded systems, recently announced the availability of the realtime operating system (OS) embOS for Atmel’s AVR32 microcontrollers.

The modern AVR32 architecture from Atmel is specially crafted to meet RTOS requirements with its fast multilevel interrupt controller, memory protection unit and the support for nested interrupts. Having an outstanding energy efficiency of 1,26 DMIPS/MHz and delivering up to 83 DMIPS (Dhrystone MIPS) performance at 66 MHz running from embedded Flash, the UC3 parts are among the highest performance flash microcontrollers on the market today.

The port of the embOS operating system from Segger to the AVR32 takes full advantage of the advanced architecture of the AVR32. embOS supports all four interrupt levels and fully nested interrupts with zero interrupt latency. The AVR32 offers a supervisor mode and an application mode for programs.

Unlike other OS, embOS runs application code (tasks) in application mode and the kernel and interrupts in supervisor mode, allowing the application program to take advantage of the protection mechanism offered by AVR32. It also reduces the amount of RAM used for stack space and makes overall memory requirements for the stack very predictable.

The embOS kernel needs only 2,5 KB of program memory and 52 Bytes of RAM, and offers a premium set of features for embedded applications. To list just a few, the graphical profiler embOSView, unlimited number of tasks, no need for pre-configuration and no assembly language required. Segger does not charge any royalties for embOS.

AT32UC3 microcontrollers' rich feature set includes up to 512 KB Flash, up to 64 KB SRAM, Ethernet MAC, Full Speed USB with OTG, 10-bit ADC, SPIs, SSC, two-wire interface (I²C compatible), UARTs, general purpose timers, 13 pulse width modulators and a full set of supervisory functions.
