Part one of term paper
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' ...

... 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 operating processors can be very complex, since there need to be dedicated communication paths between the processors, as well as software to divide the tasks among them. A practical multiprocessing system should be as simple as possible and require a minimum overhead in terms of both hardware and software. There are ...
