Abstract
A data processing system is provided that includes a processor and a memory. The processor is configured to execute instructions to access a location pointed to by an address pointer. The memory is coupled to the processor and configured to have a plurality of memory portions. A first address pointer for accessing a first portion of the memory includes a type bit field, a tag bit field, and a first address bit field. A second address pointer for accessing a second portion of the memory is configured to have only the type bit field and a second address bit field without the tag bit field. The type bit field is set to a first value for the tagged pointer and a second value for the untagged pointer. In another embodiment, a method is provided for accessing a location in the data processing system.
