Abstract: A data processor (10) has a load/store unit (28) that executes store-to-shared-data instructions before it exclusively owns the data designated by the instruction. Later, a bus interface unit (12) performs a snoop transaction to obtain exclusive ownership of the data. If data processor successfully obtains such ownership, then the data processor correctly and quickly executed the instruction with no further action required. If the data processor can not obtain ownership of the data, then data processor re-executes the instruction in the same time as if it had not acted speculatively.

Abstract: A coil unloading and transporting apparatus is disclosed and is suited for unloading coiled aluminum and other metals from a storage shaft and moving the coils from the storage shaft to a pallet for further transport. The unloading and transporting apparatus comprises a carriage movable from a position adjacent the storage shaft to a position remote from the storage shaft. A platform for supporting the coil is mounted on the carriage and a receiving shaft extends outwardly from the platform. The storage shaft can be withdrawn below the plane of the platform. The platform and the receiving shaft is pivotal from a position wherein the receiving shaft is horizontal and the coil is supported on the receiving shaft to a position wherein the receiving shaft is vertical and the coil is supported on the platform. Once the coil is supported on the platform, the receiving shaft may be withdrawn below the platform, and the coil transported by the carriage to a remote location.
