Abstract
For one or more stages of execution of a software application at a first processor, a remap vector of a second processor is reconfigured to represent a dynamic mapping of virtual address groups to physical address groups for that stage. Each bit position of the remap vector is configured to store a value indicating whether a corresponding virtual address group is actively mapped to a corresponding physical address group. Address translation operations issued during a stage of execution of the software application are selectively processed based on the configuration of the remap vector for that stage, with the particular value at the bit position of the remap vector associated with the corresponding virtual address group controlling whether processing of the address translation operation is continued to obtain a virtual-to-physical address translation sought by the address translation operation or processing of the address translation operation is ceased and a fault is issued.
