Abstract: A data processing system includes an instruction pipeline containing instruction queue circuitry, fusion circuitry and decoder circuitry. The fusion circuitry serves to identify fusible groups of program instructions within a Y-wide window of program instructions and supply a stream of program instructions including such replacement fused program instructions to a X-wide decoder circuitry which decodes X program instructions in parallel using parallel decoders.

Abstract: Apparatuses and methods of data processing are disclosed for processing circuitry having a pipeline of multiple stages. Value prediction storage circuitry holds value predictions, each associated with an instruction identifier. The value prediction storage circuitry performs look-ups and provides the processing circuitry with data value predictions. The processing circuitry speculatively issues a subsequent instruction into the pipeline by provisionally assuming that execution of a primary instruction will result in the generated data value prediction. Allocation of entries into the value prediction storage circuitry is based on a dynamic allocation policy, whereby likelihood of allocation into the value prediction storage circuitry of an data value prediction increases for an executed instruction when the executed instruction is associated with at least one empty processing stage in the pipeline.

Abstract: An apparatus has processing circuitry for executing instructions and fetch circuitry for fetching the instructions for execution. When a branch instruction is encountered by the fetch circuitry, it determines subsequent instructions to be fetched in dependence on an initial branch direction prediction for the branch instruction made by branch prediction circuitry. Value prediction circuitry is used to maintain a predicted result value for one or more instructions, and dispatch circuitry maintains a record of pending instructions that have been fetched by the fetch circuitry and are awaiting execution by the processing circuitry, and selects pending instructions from the record for dispatch to the processing circuitry.

Abstract: A digital processor, method, and a non-transitory computer readable storage medium are described, and include a load pipeline operative to access a data content and convert the data content into a load result. The digital processor also includes a value prediction check circuit that is operative to access a speculative content, determine a predicted value from the speculative content, and determine a masked value by masking the data content with a data mask. The masked value is compared to the predicted value, and an action associated with the load result is commanded based upon the comparing of the masked value and the predicted value.

Abstract: An apparatus and method are provided for using predicted result values. The apparatus has a processing unit that comprises processing circuitry for executing a sequence of instructions, and value prediction circuitry for identifying a predicted result value for at least one instruction. A result producing structure is provided that is responsive to a request issued from the processing unit when the processing circuitry is executing a first instruction, to produce a result value for the first instruction and return that result value to the processing unit. While waiting for the result value from the result producing structure, the processing circuitry can be arranged to speculatively execute at least one dependent instruction using a predicted result value for the first instruction as obtained from the value prediction circuitry.

Abstract: An apparatus and method are provided for using predicted result values. The apparatus has processing circuitry for executing a sequence of instructions, and value prediction storage that comprises a plurality of entries, where each entry is used to identify a predicted result value for an instruction allocated to that entry. Dispatch circuitry maintains a record of pending instructions awaiting execution by the processing circuitry, and selects pending instructions from the record for dispatch to the processing circuitry for execution. The dispatch circuitry is arranged to enable at least one pending instruction to be speculatively executed by the processing circuitry using as a source operand a predicted result value provided by the value prediction storage. Allocation circuitry is arranged to apply a default allocation policy to identify a first instruction to be allocated an entry in the value prediction storage.
