The AT7911E is supported by VSPWorks from Wind River, a commercially available distributed
real-time kernel. It is a multi-tasking as well as a multi-processor Operating System. The main
goals are to enable programming at a higher level to configure and to perform communication
and to administer the tasks on a board with multiple processes running in parallel.
The VSPWorks kernel supports multiple processors and application specific chips, e.g. the
TSC21020, the Sparc TSC695F, the AT697 etc.... Thus it is possible to run a heterogeneous
multiprocessor system with a single Operating System without consideration of the hardware
platform.
