The two compressed architectures described in this chapter reduce instruction size by restricting the range of literals, and by reducing the size of the instruction set and the number of registers. What are alternative ways of shrinking or compressing an instruction set?
What will be an ideal response?
Compressing code even more is not easy after you have reduced the size of the instruction set and the number
of registers. One possible solution might be to borrow a technique from nanoprogramming (in the field of
microprogramming). If a program uses only a fraction of the available instructions (i.e., a small subset), these
instructions could be replaced by pointers to the actual instructions stored in a RAM look?up table in the
processor. Of course, this approach to compression would slow processing.
