A code sequence made up multiple instructions and specifying an offset from a base address is identified in an object file. The offset from the base address corresponds to an offset location in a memory configured for storing an address of a variable…

A data processor (104) is described. The data processor (104) is capable of decoding and executing a first instruction (212) of a first instruction set and a second instruction (213-219) in a second instruction set wherein the first instruction (212)…

A data processing system includes a plurality of transaction masters (4, 6, 8, 10) each with an associated local cache memory (12, 14, 16, 18) and coupled to coherent interconnect circuitry (20). Monitoring circuitry (24) within the coherent intercon…

A data processing system is provided with multiple processors that share a main memory. Semaphore values associated with data elements within the memory system, including the main memory, are used to establish exclusive access permissions to those da…

A processor employing a post-cache (LS2) buffer. Loads are stored into the LS2buffer after probing the data cache. The load/store unit snoops the loads in the LS2 buffer against snoop requests received from an external bus. If a snoop invalidate requ…

BACKGROUND OF THE INVENTION The present invention relates to virtual machine implementations, and in particular to a safe general purpose virtual machine that generates optimized virtual machine computer programs that are executable in a general purp…

A method and mechanism for performing an unconditional stack switch in a processor. A processor includes a processing unit coupled to a memory. The memory includes a plurality of stacks, a special mode task state segment, and a descriptor table. The…
