Hi all,

mal ne Frage zur Ausführungsgeschwindigkeit von Befehlen, speziell:

Was ist schneller:

SHL o. SHR(x, n)

oder

x * o. / const( 2^n )?

Danke

Franz

Hallo Franz,

glaube lange überlegen muss man hier nicht...

SHL o. SHR(x, n) ...wird schneller sein.

Viele Grüsse

shift befehle dürften nach NOPs mit das schnellste sein
