Abstract
Techniques are disclosed involving fusing instruction pairs and executing corresponding fused instruction operations. A processor includes fusion detection circuitry to detect a pair of fetched instructions and fuse the instructions into a fused instruction operation, and execution circuitry to execute the fused instruction operation. In one embodiment, a first instruction is executable to perform an operation and a second instruction is executable to adjust a sign of a result of the operation. In another embodiment, the first instruction is executable to perform an operation and the second instruction is executable to find a maximum or minimum, as compared to a comparison operand, of a result of the operation. In another embodiment, the first instruction is executable to perform a vector operation and the second instruction is executable to read a first element of the vector result and overwrite one or more additional elements of the vector result.
