    摘要： Embodiments of the invention provide a programmable FSA building block, having a number of programmable registers and associated logic implemented therein, that provide the capability of contextually evaluating complex REs of arbitrary size against multiple data streams. Embodiments of the invention provide fully programmable hardware in which all of the states of an RE are instantiated and all of the states are fully connected. For one embodiment, the building blocks have a fixed number of states to facilitate implementation on a chip. For such an embodiment, an RE having an excessive number of states is implemented on two or more FSA building blocks and the FSA building blocks are then stitched together to effect evaluation of the RE. For one embodiment, two or more REs having a number of states less than the fixed number of states of a building block may be implemented with a single building block.

    摘要翻译： 本发明的实施例提供了一种可编程FSA构建块，其具有在其中实现的多个可编程寄存器和相关联的逻辑，其提供对多个数据流进行任意大小的复杂RE的上下文评估的能力。 本发明的实施例提供了完全可编程硬件，其中RE的所有状态都被实例化，并且所有状态都完全连接。 对于一个实施例，构建块具有固定数量的状态以便于在芯片上实现。 对于这样的实施例，在两个或更多个FSA构建块上实现具有过多状态的RE，然后将FSA构建块缝合在一起以实现RE的评估。 对于一个实施例，具有小于构建块的固定状态数量的状态数量的两个或更多个RE可以用单个构建块来实现。

    摘要： A branch prediction instruction is provided that includes hint information for indicating a storage location for associated branch prediction information in a hierarchy of branch prediction storage structures. When the hint information is in a first state, branch prediction information is stored in a first structure that provides single cycle access to the stored information. When the hint information is in a second state, the branch prediction information is stored in a second structure that provides slower access to the stored information.

    摘要： A processor having a large register file utilizes a template field for ening a set of most useful instruction sequences in a long instruction word format. The instruction set of the processor includes instructions which are one of the plurality of different instruction types. The execution units of the processor are similarly categorized into different types, wherein each instruction type may be executed on one or more of the execution unit types. The instructions are grouped together into 128-bit sized and aligned containers called bundles, with each bundle includes a plurality of instruction slots and a template field that specifies the mapping of the instruction slots to the execution unit types.
