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 trace layout of a printed circuit board (PCB) is provided with a north bridge, at least a peripheral component interconnect (PCI) slot, and an accelerate graphics port (AGP) slot. The PCB includes at least a first trace layer and a second trace layer under the first trace layer. The AGP slot is mounted between the north bridge and the PCI slot. The PCB further includes a number of first traces, and a number of second traces. The first traces are used for connecting the north bridge to the PCI slot while the second traces are used to connect the north bridge to the AGP slot. Some of the first traces are on the second trace layer under the AGP slot, while the other of the first traces are on the first trace layer or the second trace layer and trace aside the AGP slot. Most of the second traces are on the first trace layer and the other of the second traces are on the second trace layer.

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.

摘要： A circuit sub-board for regulating constant power source and strengthening ground connections. The circuit sub-board is a double-layered printed circuit board having a large surface power-source layer and a ground-connection layer. The circuit sub-board is utilized to cover the insufficiently ground-covered main board signaling lines as well as insufficiently ground-connected power and ground signaling lines on the main board. With the installation of the circuit sub-board, signals can be transmitted more reliably and with less interference.
