Engineering:MB86900
The MB86900 is a microprocessor produced by Fujitsu,[1] which implements the SPARC V7 instruction set architecture developed by Sun Microsystems. It was the first implementation of SPARC, introduced in 1986, and was used in the first SPARC-based workstation, the Sun Microsystems Sun-4, from 1987.[2][3] Its chipset operated at 16.67 MHz. The chipset consisted of two chips, the MB86900 microprocessor and the MB86910 floating-point controller. The chip set was implemented with two 20,000-gate, 1.2 μm complementary metal–oxide–semiconductor (CMOS) gate-arrays fabricated by Fujitsu Limited.[4] The MB86910 floating-point controller was designed to work together with two Weitek chips – the WTL1164 multiplier and WTL1165 arithmetic logic unit – to comprise a floating-point unit.[5]
