    摘要: A dynamic random access memory controller is suitable in controlling a first dynamic random access memory and a second dynamic random access memory, which two memory capacities are not the same. The judging circuit of the dynamic random access memory controller receives and judges whether or not a system addressing signal falls within a preset range, and outputs a judging signal. Furthermore, the transforming and shielding circuit transforms the system addressing signal and byte enable signal in accordance with the judging signal, and therefore obtains a memory addressing signal and a shielding signal for addressing the first and the second dynamic random access memories. Furthermore, the data interface circuit, in accordance with the judging signal, buffers or separates a system writing-in data signal, or, buffers or merges the memory data signal.

    摘要: A memory managing method for video data decoding process is provided. The memory managing method includes the following steps. A first frame having a first definition is stored, wherein the first frame is a first type or a second type. A second frame having the first definition is stored, wherein the second frame is the first type or the second type. A first frame having a second definition is stored in the memory space where the first frame having the first definition was originally stored, and the remaining memory space left after the original first frame having the first definition had been stored is released, wherein the memory space for storing the first frame having the first definition is greater than the memory space for storing the first frame having the second definition. A third frame having the second definition is stored, wherein the third frame is a third type.

    摘要: An architecture for video decompressor to efficiently access synchronously memory includes a synchronous memory device having an A-bank and B-bank for being stored with image data, and a memory controller for controlling data access to the synchronous memory to perform motion compensation and display. The image data has a plurality of scan lines and every four scan lines are grouped for being periodically arranged in the synchronous memory in such a manner that the A-bank is sequentially stored with (4N+0)-th and (4N+1)-th scan lines, and the B-bank is sequentially stored with the (4N+2)-th and (4N+3)-th scan lines, where N is a non-negative integer, so as to always perform memory operations by alternately accessing the A-bank and B-bank.
