Abstract
In accordance with the teachings described herein, systems and methods are provided for advanced execution of branch instructions in a microprocessor pipeline. In one embodiment, a branch instruction of an assembly language program code is executed that includes (i) a condition operand, (ii) a branch destination operand, and (iii) a program count operand. It is determined whether a current program count matches a stored program count operand. After determining that a condition was met when the branch instruction was executed, and in response to determining that the current program count matches the stored program count operand, a destination instruction specified by the stored branch destination operand is fetched.
