SPARC chip sets provide MBus expandability for high-performance SPARCstations. (Cypress Semiconductor Corp.)

EDN, August, 1992 by Weiss, Ray

Cypress Semiconductor's SPARCset is the first MBus-module-based SPARC chip set and board design. The set accepts interchangeable SPARC MBus modules, such as those used in the Sun SPARCstation 10 or Sun Galaxy multiprocessor server. The chip set does not include the modules. The board design uses the 64-bit, 40-MHz MBus as a system bus and the 25-MHz SBus as a mezzanine or peripheral bus. The design is also available from Nimbus Technology. Cypress sells the chips and the board design; Nimbus sells the SPARC Board Set, which comprises the same chips and a board ready for component insertion.

The most successful system paradigm of the 1980s was the PC. For the 1990s, SPARC chip vendors are out to repeat that success using the SPARC RISC...
