An approach to operating system testing

To ensure the reliability and performance of a new system, it must be verified or validated in some manner. Currently, testing is the only resonable technique available for doing this. Part of this testing process is the high level system test. System testing is considered with respect to operating systems and in particular UNIX. This consideration results in the development and presentation of a good method for performing the system test. The method includes derivations from the system specifications and ideas for management of the system testing project. Results of applying the method to the IBM System/9000 XENIX operating system test and the development of a UNIX test suite are presented.

A compact high-speed parallel multiplication scheme

This paper discusses a compact, fast, parallel multiplication scheme of the generation-reduction type using generalized Dadda-type pseudoadders for reduction and m x m multipliers for generation. The implications of present and future LSI are considered, a partitioning algorithm is presented, and the results obtained for a 24 x 24-bit implementation are discussed.
