摘要:
The present invention generally relates to a circuit configuration of a chip and, more particularly to a circuit configuration of a chip with a graphic controller integrated and a method for testing such a circuit configuration, in which a test circuit is employed in a main control module such that a graphic controller is directly connected to a plurality of buses in a testing mode. Thus, the testing of the graphic controller is independent of the main controller module. Moreover, the testing requests are transmitted to the graphic controller by using frequency multiplying modes, and at least one multiplexer and at least one latch are used at the memory end, so that the required pin count for testing is lowered in the present invention.
摘要:
A method for reducing computer system power consumption. The computer system includes a memory module having a plurality of address pins, and a chipset having a plurality of driving units for driving the address pins. The method includes obtaining number of required address pins by detecting a capacity of the memory module, and disabling the driving units so as to make a number of the active driving units substantially equal to the number of the required address pins.

摘要:
A method and related apparatus for performing error checking-correcting (ECC). The method divides a memory space provided by a memory into an ECC range and a non-ECC range. When data is read or written, the method determines the address of data is within the ECC range or the non-ECC range so as to decide whether error checking-correcting is performed on the data.
摘要:
A chipset has a plurality of driving units, each unit connecting to an address pin of a memory module for driving a one-bit address signal while accessing the memory module. The method detects configurations of memory modules, and determines which address pins are unused and makes corresponding driving units stop driving to reduce power consumption of unused address pins.

摘要:
A computer system includes a monitor, a memory and a processing unit. The monitor includes a main area for displaying an image. The main area has a plurality of rows and a plurality of columns of tiles. Each tile has a plurality of rows and a plurality of columns of display units, and each display unit is for displaying a portion of the image according to corresponding pixel data. The memory includes a plurality of first sequential memory units and a plurality of second sequential memory units. The first sequential memory units are for storing pixel data of a first tile. The second sequential memory units are for storing pixel data of a second tile. The second tile is horizontally next to the first tile. The processing unit sequentially transmits pixel data of pixels in the first tile before transmitting pixel data of pixels in the second tile.
