| Abstract: | The basic standards of E2PROM chip-level dynamic storage system are introduced,and the concrete realization of these basic standards are provided.The performance of the dynamic storage is assessed.By this design,the problem of the memory recovery in the E2PROM dynamic memory block is solved and a localization algorithm of free block is put forward.The structure of alike bi-directional circulatory chain table is used in records management,which meets the requirements of the chip-level dynamic memory.The performance of these designs used in large building system is very stable and reliable.Therefore,the design idea is of higher application value in the low-end embedded data management. |
