hyperSPARC

The hyperSPARC, code-named "Pinnacle", is a microprocessor that implements the SPARC Version 8 instruction set architecture (ISA) developed by Ross Technology for Cypress Semiconductor.

The hyperSPARC was introduced in 1993, and competed with the Sun Microsystems SuperSPARC. Raju Vegesna was the microarchitect. The hyperSPARC was Sun Microsystem's primary competitor in the mid-1990s. When Fujitsu acquired Ross from Cypress, the hyperSPARC was considered to be more important by its new owner than the SPARC64 developed by HAL Computer Systems, also a Fujitsu subsidiary, a view which was shared with analysts.
