RTOS extends ARM7 support to ST family

Segger's small versatile RTOS supports RVDK

Our versatile, small-footprint RTOS, Segger embOS is now available for the RVDK (Real View Developer Kit 2.1) from ST Microelectronics for ARM7 and ARM9 processors, and supports all memory models offered by this compiler.

embOS is a real-time operating system for embedded applications designed to offer the benefits of a fully fledged multitasking system at minimum cost. The kernel is fully interruptible and so efficient that it can be used in very time critical situations. The memory footprint in both RAM and ROM is so small that it can be used in single-chip applications, leaving maximum room for the user-program.

Despite its size and efficiency, embOS features the entire palette of communication mechanisms such as mailboxes, events and different kinds of semaphores. All tasks and communication instances can be dynamically created, deleted and configured. embOS provides task prioritization as well as round-robin scheduling, and features a fully interruptible, fully pre-emptive kernel.

embOS is written in "C" and assembly language. Full source code is available to developers, and the product is provided on a royalty-free basis. Being very efficient, the RTOS can be ported to any processor for which an ANSI compliant "C"-compiler exists, including most 8, 16 and 32-bit processors. Several ready-to-go ports are available including for ARM7, ARM9, Atmel AVR, Infineon C16x, Renesas H8, M16C, M32C, MIPS, Texas Instruments MSP430, Altera NIOS, NEC V850, V25 and 78Kx, Intel x86 and 8051.

embOS is also available as full functional trial version and can be downloaded. Like all evaluation versions, the new revisions supporting STM's RVDK include a complete example project, as well as API and user function call trace via embOSView.
