More information about the different power inputs is available in the hardware user’s
guide.
When the board is powered the green LED, marked with “POWER”, will light up and
the default board firmware will start to run.
The AVR UC3 family of microcontrollers offers better DSP performance than any
other 32-bit microcontroller. With its fixed-point DSP instruction set, dual port SRAM,
peripheral DMA controller, and multi-level databus, the AVR UC3 offers superior
signal processing capabilities combined with industry leading power consumption and
fast communication speeds.
Good software is necessary to unlock the superior AVR UC3 DSP performance. So
Atmel is providing the AVR UC3 DSP library, a library of basic DSP functions
optimized for performance and power consumption by Atmel’s DSP experts and
thoroughly tested. The library consists of over 70 popular DSP functions in 7
categories. These basic functions build the basis on which a wide range of signal
processing algorithms can be implemented with minimum effort. The library is
accompanied with a rich selection of examples and application notes.
AVR UC3 DSP Library is part of the AVR UC3 Software Framework, Atmel’s free of
charge collection of software examples, drivers and libraries for the AVR UC3
microcontrollers. It works on all AVR UC3 MCUs, and is known for its flexibility,
robustness and ease of use.
The real world isn’t easy to describe with integers, because their limited dynamic
range puts heavy restrictions on which numbers we can store and manipulate. That is
why digital signal processing makes use of fixed-point numbers, which allows
numbers with a decimal point ‘.’ to be stored and used in arithmetic operations. Fixed-
point arithmetic support is a requirement for fast and simple digital signal processing.
AVR UC3 is the only 32-bit MCU with support for fixed-point numbers, and the AVR
UC3 DSP library makes full use of these instructions to achieve the superior DSP
performance.
AVR UC3 DSP Library organizes functions in 7 categories.
