Abstract

A processor may include an instruction decoder to decode macroinstructions into micro-operations. In some embodiments, the instruction decoder may include a first decoder and a second decoder. The first decoder may decode a macroinstruction having SSE data type operands into a laminated micro-operation, and may generate unlamination information for the laminated micro-operation. The second decoder may generate from the laminated micro-operation and the unlamination information two or more micro-operations, where operands of the two or more micro-operations each correspond to a half of one of the SSE operands of the macroinstruction.
