The LC3020 SDK (Software Design Kit) is a POWERFUL and complete design environment. 

Each kit includes an Integrated Design Environment (IDE) based on the Eclipse open-source project (http://www.eclipse.org/) which is a complete tool chain consisting of a compiler, linker, assembler, make system, debugger, version tracking, and more.  This software is used by many large organizations such as NASA and has a huge community of users who have been contributing Q/A and code for many years.

The BACstac has been ported to the LC3020's ARM7 microprocesor running the RTEMS (Real Time Executive for Multiprocessor Systems) operating system.  The RTEMS software is an open source project ( http://www.rtems.com/ ) which also has a very large support community of top professional companies and offers many many features.  Full TCP/IP support, web servers, file systems and more are essentially "drag and drop" options.

The BACstac software is delivered as binary files able to be included with your application builds.  Examples and test software is included.  A hardware PCB is included in the kit to let you compile a working program immediately.  All relevant pins are available on this development PCB for easy connection and experimentation.
