Floating Point Coprocessors The designer of any microprocessor would like to extend its instruction set almost infinitely but is limited by the quantity of silicon available (not to mention the problems of testability and complexity). Consequently, a real microprocessor represents a compromise between what is desirable and what is acceptable to the majority of the chip's users. For example, the 68020 microprocessor is not optimized for calculations that require a large volume of scientific (i.e. floating point) calculations. One method to significantly enhance the performance of such a microprocessor is to add a coprocessor. To increase the power of a microprocessor, it does not suffice to add a few more instructions to the instruction set, but it involves adding an auxiliary processor that works in parallel to the MPU (Micro Processing Unit). A system involving concurrently op....
