    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.

    摘要: A display control device with automatic firmware update and an update method thereof are provided to update the firmware of the display control device rapidly and automatically, thereby improving user convenience and reducing user waiting time. The display control device comprises a transmission interface unit, a memory interface unit, a non-volatile memory interface unit, a first direct memory access (DMA) unit, a second DMA unit and a controller. The transmission interface unit is coupled to a code-providing unit for providing an updated code of the firmware. After detecting that the transmission interface unit is coupled to the code-proving unit, the controller automatically and temporarily stores the updated code provided by the code-providing unit into a dynamic random access memory (DRAM), and further writes the updated code into a non-volatile memory from the DRAM, thereby accomplishing automatic update of the firmware of the display control device.

    摘要: The invention discloses a patching method to correct the built-in code in read only memory (ROM), which loads the patching address stored in an external storage device and the patching content into a register and a RAM respectively. When the executing sequence reaches the patching address in the ROM, the sequence of executing jumps to the RAM to perform the patching content. After executing the patching content, the executing switches back to the ROM to execute the original executing sequence, with the present invention, the ROM chip is not necessary to be replaced when the content in the ROM needs to be corrected.
