Motorola Microsystems is attempting to establish a real-time operating system standard for VMEbus and Unix developers with its VMEexec project, running in collaboration with several of its independent software vendors. Due for release by Motorola in mid-1988 on its own VME Delta Unix systems, the product will eventually replace the Versados real-time operating system, and will define a set of software interface standards as a basis for real-time and System V applications and software development. The core of the product is the Real-Time Executive Interface Definition which defines essential operating system kernel services. Motorola is also developing a System V Interface Definition software library to interface user level processes to Real-Time Executive-compliant kernels. These will provide software developers with a more familiar programmatic interface, and will include support for network services. The project has been jointly sponsored by Motorola ISV Software Components Group of Santa Clara, and other participants include Industrial Programming Inc., and Wind River Systems. Motorola hopes to encourage other software and VME product vendors to participate in the real-time development, and has offered the specifications to the VME International Trade Association for consideration and possible endorsement. Motorola will use its own System V/68 operating system as the users’ software development platform for code generation. It promises continued maintenance for Versados users and a program for the migration of Versados software to the new product. Future releases will add support for VMEexec to run under PC-DOS. Motorola is expected to announce VME module based systems products around VMEexec in the near future.
