MicroSPARC
The microSPARC is a discontinued microprocessor implementing the SPARC V8 instruction set architecture, developed by Sun Microsystems. It is a low-end microprocessor intended for low-end workstations and embedded systems. The microprocessor was developed by Sun, but the floating-point unit was licensed from Meiko Scientific. It contains 800,000 transistors. It was used in the SPARCclassic and SPARCstation LX among others.
There are two variants of the microSPARC-II : the microSPARC-II and microSPARC-IIep. The microSPARC-II is used in the SPARCstation 5. The microSPARC-IIep is a 100 MHz microSPARC-II with an integrated PCI controller for embedded systems. It was developed and fabricated by LSI Logic for Sun, and used in their JavaStation Network Computer.
