Graphical tool speeds
secure RTOS applications

A novel tool speeds the development of high-availability embedded applications that use multiple virtual address spaces to simplify debugging and to enhance safety, security and testability

A powerful system design tool from Green Hills Software speeds the development of high-availability embedded applications that use multiple virtual address spaces to simplify debugging and to enhance safety, security and testability. Known as Integrate, the new tool allows developers to more easily take advantage of the virtual address spaces and secure interprocess communication channels offered by the company's Integrity RTOS.

Integrate's graphical front-end makes it easy for system designers to configure the system's kernel and address spaces, tasks, semaphores, connections, clocks, and other objects.

For example, developers can add new application address spaces simply by right clicking on the "canvas" and selecting the "add address space" option.

Similarly, they can add new tasks to a particular address space or create connections between address spaces by clicking inside the space and selecting the appropriate option.

Integrate clearly separates address spaces so that they can be easily viewed and distinguished from one another, simplifying the management of secure applications with multiple virtual address spaces.

The tool also enables system designers to verify system security and guarantee resource availability for critical tasks for maximum security, while powerful navigation capabilities help designers to search for and locate address spaces and tasks that are not in the viewable area of the canvas.

This makes it easy to handle large systems consisting of hundreds of address spaces and thousands of tasks in a seamless fashion.

Integrate is also context-sensitive, simplifying development by offering options that are relevant only to the selected location and system state.

Integrity is a secure, fast, deterministic, real-time operating system optimised for embedded applications that place a premium on safety, reliability, real-time performance, and testability.

Using a processor's memory management (MMU) facilities, 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 also delivers maximum responsiveness and determinism by running with interrupts continuously enabled and guaranteeing access to the CPU and memory for critical tasks.

Integrity connections facilitate message passing among tasks, whether those tasks reside in the same address space, in a different address space, or even on separate processors.

These messages can be used to transmit immediate data, buffers, kernel objects, and links to kernel objects and can be used to create message chains.

Integrate is available immediately with Integrity 4.0.
