    摘要: A data access system and a data access method achieving effects of power saving and access synchronization during data access are provided. The data access system includes a data processing unit, a bridge device and a memory device. The data processing unit sends an access request signal to initiate data access of at least one unit data. The access of unit data is completed within a plurality of clock cycles of a reference clock signal. The bridge device generates an access signal according to the access request signal, the reference clock signal and a leading time. A pulse of the access signal is determined by the leading time within the clock cycles. The memory device executes the access of the unit data according to the access signal.

    摘要: An addressing device and method is provided to enable an electronic system having a less addressing capability to address a memory device having a larger storage space, thereby reducing the manufacture cost of the electronic system. The addressing device includes an address decoder and an address translator. The address decoder receives a first access address belonging to a smaller address space, and determines whether to map the first access address to the larger storage space of the memory device. The address translator is coupled to the address decoder. When the first access address is mapped to the storage space of the memory device, the address translator translates the first access address into a second access address of the larger storage space according to an adjustable base address.
