The microSPARC processor, internally referred to as Tsunami, is a now-obsolete microprocessor that executes the SPARC V8 instruction set architecture (ISA). Created by Sun Microsystems, it was designed specifically for entry-level workstation and embedded system applications. This chip integrates a licensed floating-point unit (FPU) obtained from Meiko Scientific and comprises approximately 800,000 transistors. Systems such as the SPARCclassic and SPARCstation LX utilized the microSPARC processor.
The microSPARC-II, known by the code name Swift, comes in two distinct versions: microSPARC-II and microSPARC-IIep. The microSPARC-II variant was implemented in the SPARCstation 5, whereas the microSPARC-IIep operated at 100 MHz, featuring an embedded PCI controller aimed at embedded system markets. This version was developed and manufactured by LSI Logic on behalf of Sun Microsystems and found application in the JavaStation Network Computer.
