One of CISC's major limitations is that the instructions cannot be broken down into fast micro-instructions ----- False
CISC processors have the advantage of easy and flexible implementation of microprogramming. Therefore, they can be decomposed into fast microinstructions. It's also cheaper than wiring the entire control unit. The microcode instruction set is written to match the HLL structure, so the compiler isn't complicated either. So they are fast, have small code size and many cycles per second.
Complex instructions and therefore complex instruction decoding. Instructions are bigger than words. Instruction execution may take more than one clock cycle. Fewer general purpose registers because the operations are performed in the memory itself. Complex addressing mode.
