  • Identifying a cache way of a cache access request using information from the microtag and from the micro TLB
    Patent number: 7596663
    Abstract: A data processor operable to process data said data processor comprising: a set associative cache divided into a plurality of cache ways and operable to store data processed by said data processor; a buffer operable to store a table comprising a plurality of mappings of pages of virtual addresses to pages of physical addresses for said data processor; a data store comprising a plurality of data entries each operable to store data for identifying an address of a memory location for each of a plurality of recent cache accesses, each of said plurality of data entries comprising a page index indicating a page in an address space, offset data indicating a location within said page and cache way data identifying a cache way of a cache storage location accessed by said cache access; wherein said data processor is operable in response to a cache access request comprising a virtual address indicating a memory location to access said table and said data store to determine whether said cache access request is to one of

  • Delivering data processing requests to a suspended operating system
    Patent number: 7325083
    Abstract: In a system supporting more than one operating system, a data processing thread executing on a first operating system may be subject to an interrupt which triggers interrupt handling on a second operating system. When that interrupt handling is completed on the second operating system, the first operating system is resumed using a return interrupt. The return interrupt specifies the data processing thread which is active on the second operating system such that an appropriate task switch or resumption may be made on the first operating system. The technique is particularly well suited to systems utilising a secure operating system and a non-secure operating system executing on the same hardware.
