[Prior Art] The ever-changing technology nowadays 'for systems with processors such as embedded products, the internal memory capacity of the processor is limited, so the problem that the internal memory of the processor is not used often occurs. In this case, you only need to add an external memory for the processor to use. The processor can directly access the internal memory, so it is quite easy for the programmer to use. In contrast, the processor cannot directly access the external memory. Therefore, the instructions that must be issued are more complicated. The designer does not know the rules of the external § memory. At present, there are several methods for simplifying the process of the processor accessing the external memory, for example, designing the address to distinguish the internal memory and the external memory, and executing the required program by the driving hardware, and performing the external memory. Cutting, accessing with page instructions, planning the external memory as a circular buffer, and accessing the program mechanism configured in the external memory, but if you want to use the above method, you must first structure it. There is a degree of understanding and the prior art of the above is still not as easy to use as the processor's direct access to the internal memory. In addition, „.. & knowing technology still can't manage the external memory space, such as the helmet method, and the law should be used to store the form, etc. 201111991. It can be seen that there are still many shortcomings in the access methods of the external memory of the sacred patriots of the traditional smugglers.
