EMBEDDED WORLD: Atmel adds FPU companion for its 32-bit AVR U3 MCUs

Nuremberg, Germany – Atmel Corporation has added a floating point unit coprocessor to support its 32-bit AVR UC3 microcontrollers which it claims will allow designers to replace a two chip microcontroller and digital signal processing (DSP) device in many automotive and industrial control apps.

According to Asaid Oyvind Strom, product marketing director for Atmel's AVR microcontroller products, the addition of the Floating Point Unit improves processing performance by allowing the Atmel MCUs to perform arithmetic calculations on decimal numbers in fewer clock cycles with higher precision.

Strom said this will benefit a wide range of applications; motor control algorithms can be improved to allow the motor to run more silently or consuming less energy, sensor data can be filtered or analyzed to suppress noise and capture more useful information, and audio data can be processed without loss of fidelity.

The 32-bit AVR UC3 Floating Point Unit is compliant with the widely accepted IEEE 754 standard. This ensures compatibility with a wide range of existing math libraries and application code.

The Floating Point Unit will be introduced in selected AVR UC3 family members targeting the automotive and industrial control. The first devices are being prototyped by industry leaders today, and will be made available for general sampling in the second half of 2010.

The first devices to arrive will include advanced analog modules, such as dual high-speed 12-bit ADCs, dual high-speed 12-bit DACs and intelligent motor control. The new devices will also include features such as peripheral intelligence, memory-to-memory DMA controller and peripheral event system introduced to the UC3 microcontrollers in 2009.

The Floating Point Unit will be introduced in select products targeting the automotive and industrial control markets. Samples of the first devices will become available in the second half of 2010.
