To provide access structure and method capable of tentatively storing and transferring a command and data.
The access structure is provided with a processor core, a cache module, a prefetch module, a switcher and a tentative storage and transfer controller, the switcher is used to connect one of the cache module and the prefetch module to the processor core, the tentative storage and transfer controller detects data access behaviors of the prefetch module and an external memory device interface, when the prefetch module performs data transmission by utilizing burst transmission, the prefetch module is linked with the processor core by driving the switcher and thus, the data to be transmitted from the external memory device to the prefetch module is transmitted to the processor core together.
