Atmel Develops Floating Point Unit for 32-bit AVR UC3 Microcontrollers
Atmel Corporation announced a new technology, a Floating Point Unit, that is being designed for Atmel's 32-bit AVR UC3 product family. This new technology will enable designers to replace a two chip microcontroller and digital signal processing (DSP) solution with just one Atmel microcontroller (MCU) for applications in the automotive and industrial control markets.A fe
About a Floating Point Unit
A Floating Point Unit improves processing performance by allowing the MCU to perform arithmetic calculations on decimal numbers in fewer clock cycles with higher precision. 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 addition of a Floating Point Unit to Atmel's 32-bit AVR microcontrollers further demonstrates our commitment to push the boundaries of microcontroller performance, said Oyvind Strom, product marketing director for Atmel's AVR microcontroller products. With the increased performance, we expand the market for microcontrollers by addressing the needs of customers who now include a separate DSP on their PCB.
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.
