MicroSPARC
The microSPARC is a microprocessor implementing the SPARC V8 instruction set architecture developed by Sun Microsystems. It was 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 contained 800,000 transistors.
There were two derivatives of the microSPARC: the microSPARC-II and microSPARC-IIep. The microSPARC-IIep was a 100 MHz microSPARC-II with an integrated PCI controller for embedded systems. It was developed and fabricated by LSI Logic for Sun. The microprocessor was used by Sun in their JavaStation Network Computer.
