But note that variable and -# parallel shifts are performed by multi-media ALU and *are* pairable -# with rotates [and alike]. On the backside MMALU is rather slow: it -# takes 2 extra cycles before the result of integer operation is -# available *to* MMALU and 2(*) extra cycles before the result of MM -# operation is available "back" *to* integer ALU, not to mention that -# MMALU itself has 2 cycles latency.
