Abstract: A system may include a memory file and an execution core. The memory file may include an entry configured to store an addressing pattern and a tag. If an addressing pattern of a memory operation matches the addressing pattern stored in the entry, the memory file may be configured to link a data value identified by the tag to a speculative result of the memory operation. The addressing pattern of the memory operation includes an identifier of a logical register, and the memory file may be configured to predict whether the logical register is being specified as a general purpose register or a stack frame pointer register in order to determine whether the addressing pattern of the memory operation matches the addressing pattern stored in the entry. The execution core may be configured to access the speculative result when executing another operation that is dependent on the memory operation.

Abstract: Apparatus for creating aerodynamic lift to a downhill skier is shown as having a harness adapted to be worn by the skier, a left wing structure is operatively carried by the harness, a right wing structure is operatively carried by the harness, the left wing structure has a first longitudinal axis extending generally transversely of the skier, the right wing structure has a second longitudinal axis extending generally transversely of the skier, the left wing structure is selectively rotatable about the first longitudinal axis, the right wing structure is selectively rotatable about the second longitudinal axis, and the left and right wing structures are respectively rotatable about the first and second axes independently of each other by the skier to respective selected positions, and batten-like members are provided to enhance the airfoil configuration of the wing structures.
