    摘要: An output method for improving video image quality is provided. First, a frame data of a first frame is received, wherein the first frame may coincide with a first type or a second type. Thereafter, the first frame is subjected to a signal process step to output a processed first frame with a first standard, wherein the processed first frame comprises a first signal to noise (S/N) ratio. Next, a frame data of a second frame with a second standard is received, wherein the second frame coincides with a third type. Thereafter, a first decompression process of frame data is performed on the second frame to output a processed second frame with the first standard, wherein the processed second frame comprises a second S/N ratio. In addition, a difference between the first S/N ratio and the second S/N ratio is smaller than a predetermined minimum tolerance.

    摘要: A data communication circuit of a SDRAM for data communication comprises a plurality of data lines coupled to a plurality of data pins. The number of the data lines, according to an embodiment of the present invention, is less than the number of the data pins. When the data communication circuit receives/outputs data, one of the LDQM pin and the UDQM pin are enabled to receive/output a first part of the data. The other LDQM pin and the UDQM pin are enabled. Accordingly, the data communication circuit of the SDRAM, according to an embodiment of the present invention, is capable of transmitting more data using a bus with a narrow width.

    摘要: A memory controller capable of estimating memory power consumption includes a memory control unit, a command dispatch device, plural bank state machines and a power-state and current-accumulation device. The memory control unit generates control signals based on a memory access command sent by a system for accessing a synchronous dynamic random access memory (SDRAM). The command dispatch device synchronously receives the control signals sent by the controller to the SDRAM. The plural bank state machines are connected to the command dispatch device to receive the control signals dispatched by the command dispatch device and accordingly determine whether to transfer its internal state or not. The power-state and current-accumulation device determines on which state the SDRAM is in accordance with states of the plural band state machines, thereby computing current consumption of the SDRAM.

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 apparatus and a system having in-system-programming function are disclosed. The apparatus comprises a non-volatile memory, a controller and a serial interface unit. When the non-volatile memory is to be programmed, the controller will actively catch the program data from an external device via the serial interface unit and save the program data in non-volatile memory. Thus, the programming efficiency is enhanced, an additional programmer is unnecessary, and the production cost can be saved.
