Ross Technology, Inc.

From Wikipedia, the free encyclopedia

Ross Technology, Inc. was a semiconductor design and manufacturing company, specializing in SPARC microprocessors. It was founded in Austin, Texas in 1988; Fujitsu became a majority shareholder in the 1990s, eventually acquiring most of its assets.

Ross was a significant part of the hardware ecosystem of Sun Microsystems' SPARC-based systems of the time. They participated in the design of the MBus architecture, and also produced the hyperSPARC processor, viewed first as a competitor to Sun's own SPARC processor designs, but eventually sold as upgrades and system components by Sun itself.
