Abstract :
The Sun 4/200 workstation, launched in 1987, is powered by a new processor design developed by Sun and called the Sparc (scalable processor architecture). In Sparc the architecture is logically organised as three distinct units: an integer unit, a floating-point unit and an optional, implementation-defined coprocessor. Sparc is an example of a RISC (reduced instruction set computer) and the emphasis is on keeping instructions simple and maximising the rate at which they are executed
