摘要： A data processing device for executing a program is described. The program comprises one or more instruction groups and one or more predicates, each instruction group comprising one or more instructions. The data processing device comprises a processing unit and a trace unit connected to or integrated in the processing unit. The trace unit generates a predicate trace for tracing the values of the one or more predicates. The processing unit executes, in each of a series of execution periods, one of the instruction groups and updated the values of none, one, or more of the predicates in dependence on the respective instruction group. The trace unit appends the updated values of the none, one, or more predicates to the predicate trace and does not append any non-updated values of the predicates.A method of reporting predicate values and a data carrier are also disclosed.

摘要： A method for managing branch instructions, the method includes: providing, to pipeline stages of a processor, multiple variable length groups of instructions; wherein each pipeline stage executes a group of instruction during a single execution cycle; receiving, at a certain execution cycle, multiple instruction fetch requests from multiple pipeline stages, each pipeline stage that generates an instruction fetch request stores a variable length group of instructions that comprises a branch instruction; sending to the fetch unit an instruction fetch command that is responsive to a first in order branch instruction in the pipeline stages; wherein if the first in order fetch command is a conditional fetch command then the instruction fetch command comprises a resolved target address; wherein the sending of the instruction fetch command is restricted to a single instruction fetch command per a single execution cycle.

摘要： A system and method for modifying an information unit, the method includes the following stages: (i) receiving, over a first bus, a request to initiate a snooping type atomic operation associated with at least one information unit located at a first address of a memory module; (ii) providing the information unit over the first bus; (iii) attempting to complete the snooping type atomic operation of an updated information unit; and (iv) defining the atomic operation as a failed atomic operation if during at least one stage of receiving, providing and attempting, the first address was locked as a result of a locking type atomic operation.

摘要： A method for speculative execution of instructions, the method includes: decoding a compare instruction; speculatively executing, in a continuous manner, conditional instructions that are conditioned by a condition that is related to a resolution of the compare instruction and are decoded during a speculation window that starts at the decoding of the compare instruction and ends when the compare instruction is resolved; and stalling an execution of a non-conditional instruction that is dependent upon an outcome of at least one of the conditional instructions, until the speculation window ends.
