Green Hills Offers INTEGRITY Board Support Package for Atmel's ARM-based Microcontroller

2/20/2003 - Atmel® Corporation (Nasdaq: ATML) and Green Hills® Software Inc. announced the availability of a Green Hills Software INTEGRITY® Board Support Package (BSP) for Atmel's AT91RM9200 ARM-based microcontroller. The INTEGRITY port provides maximum functionality and security at a minimal OS overhead by fully exploiting the advanced features of the AT91RM9200 architecture such as the Memory Management Unit (MMU), Advanced Interrupt Controller (AIC) and on-chip DMA capabilities. Benefits to the programmer include a deterministic response to critical events, a fully protected virtual address space and minimum interrupt latency.

INTEGRITY delivers maximum responsiveness and determinism by utilizing the AT91RM9200 fast context switching features, running with interrupts continuously enabled and by guaranteeing access to the CPU and memory for critical tasks. In addition, by utilizing the AT91RM9200 MMU, INTEGRITY builds a firewall between the kernel and user tasks that prevents errant or malicious code from corrupting other user tasks or the kernel.

INTEGRITY is tightly integrated with the MULTI Integrated Development Environment (IDE), which, together with Green Hills Software's family of C/C++/EC++ optimizing compilers, automates all aspects of embedded Atmel software development. MULTI features an INTEGRITY-aware source-level debugger, graphical program builder, run-time error checker, version control system, and performance profiler. MULTI also features an INTEGRITY simulator (ISIM), which enables programmers to develop and test their code on a PC or workstation without the need for target hardware; and a real-time EventAnalyzerô, which enables users to view system and user events in a graphical display.

INTEGRITY is a royalty-free, state-of-the-art real-time operating system designed for modern 32- and 64-bit embedded processors. It is aimed at high-reliability, always-on applications in telecommunications, defense, networking and medical equipment.

The AT91RM9200 is built around the ARM920T 200+ MIPS advanced 32-bit RISC microprocessor from ARM Ltd. It embeds on-chip SRAM and ROM and can be connected to a wide range of off-chip memories and storage devices such as CompactFlash, SmartMedia, SD Cards and Atmel DataFlash cards. In addition it integrates an extensive set of peripherals for control and communication including a USB Host and Device and an Ethernet 10/100 Base T MAC. A sophisticated power management controller minimizes power consumption under all operational conditions.

Jacko Wilbrink, Atmel's ARM-based Product Manager commented, "Porting INTEGRITY onto the AT91RM9200 at the time of its release enables design engineers to make an immediate start on their application developments. By taking care of prioritization, scheduling and memory management issues INTEGRITY significantly reduces the development time for applications and leads to a better-quality result. This port also indicates the level of confidence of one of our market-leading software partners in Atmel's first ARM920T-based standard product.

"Through our 5-year partnership, Green Hills Software and Atmel have collaborated together to offer customers optimized, royalty-free solutions based around the popular AT91 family", said John Carbone, vice president of marketing at Green Hills Software. "Green Hills is very pleased to help Atmel launch their impressive new AT91RM9200 and expect customers to highly value the part's advanced features, high speed and low power consumption."
