VLSI/LSI Circuit Functions: Their Chanllenges, Rewards, and Problems

Sperry Univac is concluding, the development of a family of very large to large scale integrated (VLSI/LSI) bipolar logic components. These parts supply universal functions in general computer applications and are not unique to a specific system. This approach is, in itself, unique for a computer mainframe manufacturer, since these designs are not proprietary and are meant for off-the-shelf commercial usage. If the volume objectives are met, the price of these components will be attractive to other users, and the components will be used over a broad range of application and speed. A description of the functions, the logic density, the technology, and the circuits used are covered. A comparison of these functions to their small to medium scale integrated (SSI/MSI) components is also discussed. Finally the areas of schedules, costs, and problems encountered are covered.
