Predicting a load value for a subsequent load operation

A method comprising:

• executing load operations, each load operation being associated with an identifier indicative of a position of the load operation in a sequence of load operations;
• receiving a given load value indicative of a value read in response to execution of a given load operation, the given load operation being associated with a given identifier,
• making, in dependence on the given load value, at least one prediction indicating a predicted load value for a subsequent load operation to be executed and an ID-delta value indicating a difference between the given identifier and an identifier of the subsequent load operation;
• determining the predicted load value in dependence on at least one occurrence of each of the given load value and the predicted load value being observed during execution of a previously-executed sequence of load operations;
• and
• determining the ID-delta value in dependence on a difference between identifiers associated with the at least one occurrence of each of the given load value and the predicted load value in the previously-executed sequence of load operations.

A non-transitory computer-readable storage medium to store computer-readable code for fabrication of an apparatus comprising:

• processing circuitry to execute load operations, each load operation being associated with an identifier indicative of a position of the load operation in a sequence of load operations;
• and
• prediction circuitry to receive a given load value indicative of a value read in response to execution of a given load operation, the given load operation being associated with a given identifier,
• wherein the prediction circuitry is configured to make, in dependence on the given load value, at least one prediction indicating a predicted load value for a subsequent load operation to be executed by the processing circuitry and an ID-delta value indicating a difference between the given identifier and an identifier of the subsequent load operation;
• and
• wherein the prediction circuitry is configured to determine the predicted load value in dependence on at least one occurrence of each of the given load value and the predicted load value being observed during execution of a previously-executed sequence of load operations;
• and
• wherein the prediction circuitry is configured to determine the ID-delta value in dependence on a difference between identifiers associated with the at least one occurrence of each of the given load value and the predicted load value in the previously-executed sequence of load operations.
