ARM dev't tools
IAR Embedded Workbench for ARM is a set of highly sophisticated and easy-to-use development tools. It incorporates an ARM Cortex-M3 C/C++ compiler, assembler, linker, librarian, text editor, project manager, and debugger combined in an integrated development environment for programming embedded applications. In addition to supporting debugging through the JTAG port, IAR Embedded Workbench also supports Serial Wire Output (SWO), which is part of CoreSight, the on-chip debug and trace solution used in the Cortex processor family and in the Atmel SAM3U. The user has full freedom to configure the types of packets sent over the SWO channel that should be displayed by IAR C-SPY debugger. Additionally, debug log messages from a print output can be also displayed by IAR C-SPY, without having to halt the execution.

IAR Embedded Workbench for ARM is developed to deliver high performance compiled code. The chip-specific code optimiser generates very efficient and reliable flashable code for the Atmel MCUs. Recently added, multi-file compilation is a feature that allows the compiler to treat several files as one compilation unit that means it can optimise over a larger scope of code.

IAR PowerPac is a family of RTOS, file system and USB and TCP/IP communication stacks. It is integrated with IAR Embedded Workbench for ARM to ensure quick and easy project start-up and application development.

Atmel's SAM3U device is the industry's first ARM Cortex-M3 flash MCU integrating high speed (480Mbps) USB Device-and-Transceiver, 4bit 192Mbps SDIO/SDCard 2.0, 8bit 384Mbps MMC 4.3 host and 48Mbps SPI interfaces on-chip. This connectivity, together with the SAM3U's 96MHz/1.25 DMIPS/MHz operating frequency, makes the SAM3U the unique Cortex-M3 device suited to applications with intensive communications requirements, such high speed gateways in industrial, medical, data processing and consumer applications. The introduction of the SAM3U expands Atmel's 32bit MCU portfolio consisting of ARM and AVR32 products.
