摘要： An energy-saving light-emitting module is provided, comprising: a light guide plate having a light-incident surface, a bottom surface intersecting the light-incident surface and a light-emitting surface opposite the bottom surface, wherein a plurality of recesses are provided at the bottom surface; a light source placed at one side of the light-incident surface of the light guide plate; and a reflective plate placed at the bottom of the light guide plate for reflecting light rays from the light source into the light guide plate. The light rays emitted by the light source reach the arc surface of each recess at the bottom side of the light guide plate, and the light rays are then reflected to the light-emitting surface. Meanwhile, during the light-emitting process, light rays are concentrated at the arc surface of each recess. The concentration of light rays increases overall luminance produced by the module, and thus, energy is saved effectively.

摘要： A memory access control method and system is provided for use on a computer system to control the memory access operation by a central processing unit (CPU) to a memory unit in a more efficient manner than the prior art. This memory access control method and system is characterized by, for each read request from the CPU, the prompt transfer of the corresponding internal read-request signal to the memory control unit, right after it is issued and without waiting until the CPU issues the L1 write-back signal of the current read request. If the current read request is a hit to the cache memory, a read-stop signal is promptly issued to stop the current read operation on the memory unit, and then a cache write-back operation is performed to write the cache data back into the memory unit. This method and system can help reduce the period of waiting states by the CPU, thus increasing the overall memory access performance by the CPU and the overall system performance of the computer system.

摘要： An apparatus and method capable of programmably delaying a clock of a memory. The apparatus and method utilize the BIOS, external electric switches or other logic devices to selectively delay the clock of the DRAM and/or the internal clock of the north bridge, by which the DRAM has enough setup time at the rising edge of work clock to correctly read out the command word. The north bridge can then correctly receive data from the DRAM module and transfer the data to the CPU or AGP. Therefore, the memory can function normally even if the memory is operated at high speed or with heavy loading.
