<p>A description is given of the Gmicro/FPU (floating-point unit), a chip that provides floating-point instructions for both the Gmicro/200 and the Gmicro/300 microprocessors. The VLSI central-processing-unit architecture, for which it is designed, defines 23 coprocessor instructions, some of which are designed to be used in the floating-point instructions. Some background information is given, and the requirements, architecture, implementation, and evaluation of the Gmicro/FPU are discussed.</p>
