Manipulation of boolean values and conditional operation in a microprocessor

A method for performing a plurality of operations in a microprocessor, said microprocessor including an arithmetic logic unit and a plurality of general purpose registers and performing one or more operations in each of a series of clock cycles, said operations comprising one or more arithmetic operations and comprising one or more comparison operations, at least one of said arithmetic operations being conditioned on the result of a comparison operation previously performed, comprising the steps of:

• performing a comparison operation in said arithmetic logic unit, and obtaining thereby a Boolean value representing the result of said comparison operation;
• storing said Boolean value in a first general purpose register in the same clock cycle as that in which said comparison operation is performed;
• and
• thereafter, performing an arithmetic operation in said arithmetic logic unit and storing the result of said arithmetic operation in a second general purpose register, however, said step of performing being conditioned on the Boolean value stored in said first general purpose register.
