Original: Complex addressing performed via sequences of arithmetic and/or load-store operations; Few data types in hardware, some CISCs have byte string instructions, or support complex numbers; this is so far unlikely to be found on a RISC.
Simplified: Complex addressing performed via sequences of arithmetic and/or load-store operations. Few data types in hardware, some CISCs have byte string instructions, or support complex numbers; which is almost not found on a RISC.
