Method and apparatus for fast decoding of microinstructions are disclosed. An integrated circuit is disclosed wherein microinstructions are queued for execution in an execution unit having multiple pipelines where each pipeline is configured to execute a set of supported microinstructions. The execution unit receives microinstruction data including an operation code (opcode) or a complex opcode. The execution unit executes the microinstruction multiple times wherein the microinstruction is executed at least once to get an address value and at least once to get a result of an operation. The execution unit processes complex opcodes by utilizing both a load/store support and a simple opcode support by splitting the complex opcode into load/store and simple opcode components and creating an internal source/destination between the two components.
A method for processing instructions represented by opcodes in an execution unit having multiple pipelines, the method comprising:
An integrated circuit (IC) comprising:
A non-transitory computer-readable storage medium storing a set of instructions for execution by one or more processors to facilitate a design or manufacture of an integrated circuit (IC), the IC comprising:
