摘要： A layout structure of a central processing unit (CPU) that supports two different package techniques, comprising a motherboard that comprises the layout structure and a layout method. The layout structure of the preferred embodiment according to the present invention from up to down sequentially places a top signal layer, a grounded layer, a power layer having a grounded potential, and a bottom solder layer in the area where the signals of the CPU are coupled to the signals of the control chip, so that the signals that are placed on the bottom solder layer can refer to a grounded potential area of the power layer. Therefore, part of signals of the CPU that are coupled to the control chip can be placed on the bottom solder layer. Since the preferred embodiment of the present invention provides more flexibility in the placement design, a layout structure that supports the Pentium IV CPUs of different package techniques can be designed on the motherboard of the 4 layers stack structure, and these two CPUs can be supported by the same control chip.

摘要： A chipset to support multiple CPU's and a layout method thereof. Those independent signal lines for delivering high frequency clock signals of the chipset are isolated from using by other signals without being multiplexed. Trace length of the independent signal line is shorter than that of the others. The spaces between the independent signal line and others are also larger than that between other signal lines. Signal transmission quality is significantly upgraded because the high frequency clock signal is not multiplexed and isolated from others.

摘要： A memory control system for controlling write-enable signals. The memory control system has a first memory slot having a write-enable pin thereon, a second memory slot having a first write-enable pin and a second write-enable pin thereon and a control chipset having a write-enable pin and a dual-purpose write-enable/memory-parity-data pin thereon. The write-enable pin of the control chipset is connected to the write-enable pin of the first memory slot and the first write-enable pin of the second memory slot. The write-enable/memory-parity-data pin of the control chipset is connected to the second write-enable pin of the second memory slot. In this invention, since the design of the write-enable system is more flexible, length of trace line on a computer board can be greatly reduced. In addition, the system permits the incorporation of one cycle (1T) timing into design of memory access commands.
