To truly appreciate the breadth of features the Abassi real-time kernel provides, we encourage you to review the User's Guides. They provide a complete and very detailed view of the internals of the kernel, and fully illustrates the configurablility and richness of Abassi.
The common features of the 3 RTOS are described in the single core Abassi User's Guide. The multicore version mAbassi re-uses everything from the single-core kernel, therefore mAbassi User's guide is in fact an add-on to the single core Abassi User's Guide. μAbassi the introductory multicore RTOS, is a subset of mAbassi and the μAbassi User's Guide is itself an add-on over mAbassi User's Guide.
