摘要： A data processing system includes a first interrupt controller with an interrupt source interface, an interrupt controller interface, a prioritizer, and an interrupt controller output. The data processing system further includes a processing unit providing an interrupt controller interface. Interrupt requests generated by a first plurality of interrupt sources, a second selected interrupt request, a second priority signal, and a second interrupt source index signal generated by a second interrupt controller are received by the first interrupt controller. From the plurality of interrupt requests and the second selected interrupt request, a first single interrupt request is selected and transmitted to the processing unit along with a first priority signal, and a first index signal. The processing unit initiates an appropriate interrupt service routine on the basis of said first index signal.

摘要： A way prediction scheme for a partitioned cache is based on the contents of instructions that use indirect addressing to access data items in memory. The contents of indirect-address instructions are directly available for use, without a memory address computation, and a prediction scheme based on this directly available information is particularly well suited for a pipeline architecture. Indirect addressing instructions also provide a higher-level abstraction of memory accesses, and are likely to be more indicative of relationships among data items, as compared to the absolute address of the data items. In a preferred embodiment, the base register that is contained in the indirect address instruction provides an index to a way-prediction table for an n-way associative cache. Data items that are indirectly addressed using the same base register are likely to be related, and thus predicting a particular way in an n-way associative memory based on the base register of an indirect address instruction is likely to result in a cache-hit, thereby reducing the energy consumption associated with accessing all ways in the cache.
