Abstract
A processor coupled to a memory for providing a pointer in order to access a corresponding memory address, the pointer being updated by adding a predetermined increment according to logic integral with the processor. A method is disclosed for updating the pointer to a value other than that dictated by the processor logic so as to access an arbitrary memory address dictated by an application program accessing the processor. The method comprises disabling the logic in respective of the pointer, processing the application program so as generate a successive memory address for accessing the memory, and setting the pointer to the successive memory address instead of incrementing the pointer by the predetermined increment dictated by the logic. The processor may be a DSP having an internal post-modification unit for updating each of the pointers by adding a predetermined increment so as to assign a new address to the respective pointer, and a logic circuit for selectably disabling the internal post-modification unit in respect of one or more of the pointers and enabling external post-modification of the respective pointers.
