Abstract: A processor remaps stored data and the corresponding memory addresses of the data for different processing units of a heterogeneous processor. The processor includes a data remap engine that changes the format of the data (that is, how the data is physically arranged in segments of memory) in response to a transfer of the data from system memory to a local memory hierarchy of an accelerated processing module (APM) of the processor. The APM's local memory hierarchy includes an address remap engine that remaps the memory addresses of the data at the local memory hierarchy so that the data can be accessed by routines at the APM that are unaware of the data remapping. By remapping the data, and the corresponding memory addresses, the APM can perform operations on the data more efficiently.
