摘要： There is provided a system havingan execution core operable to execute internal instructions.A translation buffer is operable to store a plurality of internal instruction blocks of one or more internal instructions where the internal instruction blocks are a dynamic translation of respective external instruction blocks of one or more external instructions.A remapper is responsive to an execution request for an external instruction that is within one of said external instruction blocks to identify a corresponding internal instruction block stored within said translation buffer. Thus one or more internal instructions from said corresponding internal instruction block can be supplied to execution core.

摘要： An accelerator 120 is tightly coupled to the normal execution unit 110. The operand store, which could be a register file 130, a stack based operand store or other operand store is shared by the execution unit and the accelerator unit. Operands may also be accessed as immediate values within the instructions themselves. The sequences of individual program instructions corresponding to computational subgraphs remain within a program but can be recognized by the accelerator as suitable for acceleration and when encountered are executed by the accelerator instead of by the normal execution unit. Within such tightly coupled arrangement problems can arise due to a lack of register resources within the system. The present technique provides that at least some intermediate operand values which are generated within the accelerator, but are determined not to be referenced outside of the computational subgraph concerned, are not written to the operand store.

摘要： A data processing apparatus and method are provided for processing data under control of a program having program instructions including sequences of individual program instructions corresponding to computational subgraphs identified within the program. Each computational subgraph has a number of input operands and produces one or more output operands. The apparatus comprises an operand store for storing the input and output operands, and processing logic for executing individual program instructions from the program. Also provided is configurable accelerator logic which, in response to reaching an execution point within the program corresponding to a sequence of individual program instructions corresponding to a computational subgraph, evaluates one or more output functions associated with the computational subgraph. The evaluation of each output function generates an output operand for storing in the operand store, and each output operand corresponds to an output that would have been generated had the sequence of individual program instructions corresponding to the computational subgraph have been executed by the processing logic. Configuration storage stores a single look-up table (LUT) configuration for each output function, and for each output function to be evaluated, the accelerator logic is configured dependent on the associated single LUT configuration from the configuration storage, such that on receipt of the input operands of the computational subgraph, the accelerator logic will generate the output operand. This technique has been found to provide a particularly efficient accelerator logic for evaluating output functions associated with computational subgraphs.

摘要： A data processing system is provided having a processor and analysing circuitry for identifying a SIMD instruction associated with a first SIMD instruction set and replacing it by a functionally-equivalent scalar representation and marking that functionally-equivalent scalar representation. The marked functionally-equivalent scalar representation is dynamically translated using translation circuitry upon execution of the program to generate one or more corresponding translated instructions corresponding to a instruction set architecture different from the first SIMD architecture corresponding to the identified SIMD instruction.
