pl.. poveikis baiges.. ziuriu, kad toliau kliedim :D..

Inteliniai abalio procai yra truly truly non RISC..

Apie tarsi RISC suprantantis "x86" gal kazkiek:
https://en.wikipedia.org/wiki/Intel_Atom#Microarchitecture

Those Atom processors are able to execute up to two instructions per 
cycle. Like many other x86 microprocessors, they translate 
x86-instructions (CISC instructions) into simpler internal operations 
(sometimes referred to as micro-ops, i.e., effectively RISC style 
instructions) prior to execution. The majority of instructions produce 
one micro-op when translated, with around 4% of instructions used in 
typical programs producing multiple micro-ops. The number of 
instructions that produce more than one micro-op is significantly fewer 
than the P6 and NetBurst microarchitectures. In the Bonnell <..>

bet jei OS'as yra x86-instruction set'o.. tai cia grynai proco reikalas 
issiverst tas instrukcijas i savo makaulei suprantamus micro-ops'us.
