Atmel and SEGGER Announce Real Time OS Support to AVR32 Architecture

San Jose, California (ots/PRNewswire) -

Atmel(R) Corporation (Nasdaq: ATML) and SEGGER Microcontroller, a
leading manufacturer of middleware for embedded systems, announced
today the availability of the real time operating system (OS) embOS
for the AVR(R)32 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 1.08 DMIPS/MHz and delivering up
to 83 Dhrystone MIPS (DMIPS) performance at 66 MHz running from
embedded flash the UC3 parts are among the highest performance flash
microcontrollers in 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.

"We are very excited to bring embOS support for our AVR32
products," said Dr. Oyvind Strom, Product Line Director at Atmel.
"embOS is very efficient and well written with the limited resources
of microcontrollers in mind. Just like the AVR32, embOS has been
optimized for very fast interrupt handling, which makes embOS and
AVR32 the perfect combination in timing critical applications."

"The AVR32 is well equipped to play a major role in the important
32-bit market," said Robert Teufel, COO at SEGGER. "With embOS,
SEGGER offers a tailored OS for this new, high performance
microcontroller family."

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, thirteen pulse width modulators and a full
set of supervisory functions.
