Abstract
Methods and apparatus for enhanced microcode address stack pointer manipulation are described. In some examples, the stacks are invisible to software. A microcode instruction pointer (UIP) and a next address to be accessed in a microcode storage unit may be generated based on an opcode of a microoperation, a marker, and a UIP stack address. The UIP stack address may be generated based on a signal and an immediate field of the microoperation.
