Figure 7.2, 7.3 of Text (pgs. 188, 189)
Show evolution of current superscalar processors
Interesting differences between CISC ISAs (x86, 68000) and RISC ISAs
- RISC ISAs have higher instructions/clock than CISC ISAs because of lower complexity
- RISC ISAs had superscalar implementations before CISC ISAs.
- Text mentions that in some implementations, CISC instructions are converted on the fly to multiple RISC instructions for more efficient processing (AMD K5 implementation of x86 ISA).
