The microSPARC (code-named Tsunami) is a discontinued microprocessor implementing the SPARC V8 instruction set architecture (ISA), 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 (FPU) 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 (code-named Swift): 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.

SPARCstation 5 or SS5 is a workstation introduced by Sun Microsystems in March 1994. It is based on the sun4m architecture, and is enclosed in a pizza-box chassis. Sun also offered a SPARCserver 5 without a framebuffer. A simplified, cheaper version of the SS5 was released in February 1995 as the SPARCstation 4. Sun also marketed these same machines under the "Netra" brand, without framebuffers or keyboards and preconfigured with all the requisite software to be used as web servers. An estimated 400,000+ SPARCstation 5s were sold.

OpenSPARC is an open-source hardware project, started in December 2005, for CPUs implementing the SPARC instruction architecture. The initial contribution to the project was Sun Microsystems' register-transfer level (RTL) Verilog code for a full 64-bit, 32-thread microprocessor, the UltraSPARC T1 processor. On March 21, 2006, Sun released the source code to the T1 IP core under the GNU General Public License v2. The full OpenSPARC T1 system consists of 8 cores, each one capable of executing four threads concurrently, for a total of 32 threads. Each core executes instruction in order and its logic is split among 6 pipeline stages.
