Abstract
Operation of a multi-slice processor that includes a plurality of execution slices and a plurality of load/store slices coupled via a results bus includes: retrieving, from the results bus into an entry of a register file of an execution slice, speculative result data of a load instruction generated by a load/store slice; and determining, from the load/store slice after expiration of a predetermined period of time, whether the result data is valid.
