Abstract
The present invention relates to multiprocessors which has several microprocessors on a single chip. Efficiency is improved by stripping certain functions that are used less freely from the microprocessor and sharing these functions between several symmetric microprocessors. This method allows each CPU to occupy a smaller area while preserving complete symmetry of capability for software simplification. For example, the shared execution units can include the floating point unit and multimedia execution units.
