Abstract: The disclosed software framework and development platform facilitates software development for multi-sensor systems. In some implementations, developers can select a sensor board that includes a desired combination of sensor devices. The sensor board can be coupled to a development board that includes a target processor and other circuitry to facilitate development and testing of a system that includes the target processor and the sensors. Various software support tools are provided including an Application Programming Interface (API) that provides API abstractions for software drivers for the sensors on the sensor board. By using the abstractions of the API, a software developer does not have to write code (“glue”) to interact with the various software drivers. Additionally, the API provides access to a variety of software library functions for performing data scaling, unit conversion and mathematical functions and algorithms.

Abstract: A protection domain system is implemented to provide protection for applications executing in a computing environment. Protection domains are allocated system resources and may contain executing tasks. The protection domain system may allow tasks to access resources in other protection domains to which attachments have been made. Attachment is transparent to the software developer. The protection domain system provides flexibility in implementing operating system services and defining protection hierarchies.

Abstract: The present invention logs events which occur in the target software, and stores these in a buffer for periodic uploading to a host computer. Such events include the context switching of particular software tasks, and task status at such context switch times, along with events triggering such a context switch, or other events. The host computer reconstructs the real-time status of the target software from the limited event data uploaded to it. The status information is then displayed in a user-friendly manner. This provides the ability to perform a logic analyzer function on real-time software. A display having multiple rows, with one for each task or interrupt level, is provided. Along a time line, an indicator shows the status of each program, with icons indicating events and any change in status.
