    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 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.

    摘要： An integrated circuit device comprising an instruction processing module for performing operations on data in accordance with received instructions. The instruction processing module comprises a context selector unit arranged to selectively provide access to at least one process attribute(s) within a plurality of process contexts in accordance with at least one context selector value received thereby. The instruction processing module is arranged to receive an instruction comprising a context indication for a process attribute with which an operation is to be performed, provide the context selector value based at least partly on the context indication to the context selector unit, and execute the operation to be performed with the process attribute for at least one process context to which the context selector unit provides access in accordance with the context selector value.

    摘要： A system for instructing a data processor, the system including an instruction root having an operation selection field for selecting an operation to be performed by said data processor and an instruction prefix. The instruction prefix has a field selected from the group of a conditional execution field for selecting a condition under which a data processor will perform said selected operation, an operand length modification field for modifying the selected operation so as to be performed on an operand having a different length, an instruction group field for selecting a length of an instruction group that includes the instruction root, and a prefix length selection field for selecting a length of said instruction prefix. A data processor system responsive to this instruction system is also disclosed. An instruction system for statically grouping instructions without using an instruction prefix is also disclosed.
