Do compressed architectures represent an advance or a regression in computer development? Use examples to justify your answer.
What will be an ideal response?
Neither (in my opinion). Computer science and computer architecture are concerned with the best utilization of
resources. Long instruction words are efficient in the sense that a lot of registers and operations can be
specified. However, they require wide memory systems and are more expensive than small memory systems (cost is less important in the PC world than in the world of cell phones and MP3 players, where a few dollars on
the cost of a unit is a lot of money when units are made by the tens of millions).
Compressed code uses a smaller instruction set and less registers to compress code. In that sense it is a step
backwards, because instructions look more like traditional 8? and 16?bit microprocessor code. However, many
RISC principles are retained and the system is still efficient.
