Some embodiments present a method of performing a variable shift operation. This method can be used by a microprocessor that does not allow variable shift operation for certain operand sizes. The method simulates a shift instruction that shifts an operand by a shift count. The method identifies a first...http://www.google.fr/patents/US8024552?utm_source=gb-gplus-shareBrevet US8024552 - Performing variable and/or bitwise shift operation for a shift instruction that does not provide a variable or bitwise shift option
