Green Hills Software has has produced a version of its royalty-free Integrity 4.0 RTOS for the Intel x86/Pentium architecture. Featuring a memory-protected, micro-kernel architecture that guards against viruses, hackers, and errant code, Integrity provides guaranteed resource availability for CPU and memory access. As a result, it is ideal for demanding real-time applications.

Integrity is a fast, deterministic RTOS designed for applications that require high reliability, small size, and real-time responsiveness.

Using the hardware memory protection facilities of the x86 MMU, Integrity builds a firewall between the kernel and user tasks.

This prevents errant or malicious tasks from corrupting user data, the kernel, interprocess communications, device drivers and other user tasks.

Integrity also enhances reliability and determinism by running with interrupts continuously enabled and guaranteeing access to the CPU and memory for critical tasks.

A graphical ResourceAnalyzer and real-time EventAnalyzer, along with versatile I/O, file system, and networking support, help to simplify the implementation of x86/Pentium applications based on the Integrity RTOS.

Offering comprehensive I/O and file system support, Integrity includes a USB stack, NFS client, and drivers for I2C, CompactPCI/VMEbus backplanes, clocks, timers, and standard PC peripherals.

The RTOS features a Unix-compatible, hierarchical file system, and a Posix API.

Networking support includes a TCP/IP stack, 10/100 and gigabit Ethernet drivers, along with adaptation layers for both Rational Rose RealTime and I-Logix Rhapsody modelling tools.

Support for a full line of embedded Internet software products and applications makes it easy to add web connectivity and management to intelligent storage systems.

Integrity's graphical ResourceAnalyzer greatly enhances visibility into applications and the kernel as they execute on the target system, displaying CPU execution at the task and address space level, stack usage for tasks, and memory use for address spaces.

The real-time EventAnalyzer further enhances real-time visibility by enabling programmers to log and monitor system and application events in real time without disrupting program execution.

The EventAnalyzer is also tightly integrated with Rational Rose RealTime, enabling programmers to view RoseRT state transitions and Integrity events.

Integrity is integrated with the Green Hills Multi and AdaMulti Integrated Development Environment.

Together with the Green Hills family of optimising Ada95, C, C++, and EC++ compilers, Multi automates all aspects of embedded software development for x86 processors, including editing, source-level debugging, program building, run-time error checking, version control, and code/performance optimisation.

Multi also features ISIM, an Integrity simulator that enables programmers to develop and test their x86 code on a PC or workstation without the need for target hardware.

Integrity works out of the box with PC-compatible ISA/EISA, PCI, and PC/104 boards.

In addition, Green Hills offers a porting kit and turnkey porting services for designers who want to port Integrity to other platforms.
