Abstract
The invention provides a design method of a mainboard with dual CPUs (central processing units) with asymmetric memories. The method includes the design steps: dividing the mainboard into a left portion and a right portion, arranging one CPU on each portion, vertically arranging four memory slots on the CPU1 on the left portion respectively, vertically arranging six memory slots on the CPU0 on the right portion respectively, arranging a south bridge chip below the bottom memory slot of the right portion, arranging six PCIE (peripheral component interface express) slots below the memory slots of the left portion, enabling the CPU0 to be externally connected with twelve memories, and enabling the CPU1 to be externally connected with eight memories. Since the CPU0 is externally connected with the twelve memories, the CPU1 is externally connected with the eight memories, and the PCIE slots are six, PCIE I/O (input/output) of the mainboard is expanded effectively.
Description
Technical field
The present invention relates to a kind of Computer Applied Technology field, specifically a kind of pair of CPU asymmetry internal memory motherboard design method.
Background technology
Nearly 24 of the internal memories that Intel RomleyEP platform can dispose, at present industry mainstream standard mainboard be designed and sized to 12x13inch, if but in the mainboard of 12x13inch, design 24 root memories and will cause the PCIE I/O expansion of mainboard to be extremely restricted.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, and a kind of pair of CPU asymmetry internal memory motherboard design method is provided.
Technical scheme of the present invention realizes in the following manner, design procedure is as follows: with mainboard few two parts about me, each part arranges a CPU, the CPU1 of left half arranges respectively up and down 4 memory banks, and the CPU0 of right half arranges respectively up and down 6 memory banks, and the below of right half below memory bank arranges South Bridge chip, the memory bank below of left half arranges 6 PCIE slot slots, external 12 root memories of this design CPU0, external 8 root memories of CPU1, totally 6 of PCIE slot.
Outstanding beneficial effect of the present invention: mainboard adopts two CPU internal memory asymmetric design, and the PCIE I/O of the mainboard that makes is effectively expanded.
Description of drawings
The structural representation of the mainboard that accompanying drawing 1 is.
Embodiment
Below in conjunction with accompanying drawing method of the present invention is described in further detail.
Now design a kind of pair of asymmetrical mainboard of CPU internal memory (internal memories of two identical external varying numbers of CPU), guaranteeing to guarantee in the more situation of amount of memory that PCIE Slot quantity is more than enough.
Design procedure is as follows:
With mainboard few two parts about me, each part arranges a CPU, the CPU1 of left half arranges respectively up and down 4 memory banks, the CPU0 of right half arranges respectively up and down 6 memory banks, the below of right half below memory bank arranges South Bridge chip, and the memory bank below of left half arranges 6 PCIE slot slots, external 12 root memories of this design CPU0, external 8 root memories of CPU1, totally 6 of PCIE slot.
External 12 root memories of this design CPU0, external 8 root memories of CPU1, totally 6 of PCIE slot.As shown in Figure 1.The PCIE I/O of mainboard is effectively expanded.
Except the disclosed technical characterictic of instructions of the present invention, be the public office technology of those skilled in the art.
Claims (1)
1. two CPU asymmetry internal memory motherboard design method, it is characterized in that, design procedure is as follows: with mainboard few two parts about me, each part arranges a CPU, the CPU1 of left half arranges respectively up and down 4 memory banks, the CPU0 of right half arranges respectively up and down 6 memory banks, the below of right half below memory bank arranges South Bridge chip, the memory bank below of left half arranges 6 PCIE slot slots, external 12 root memories of this design CPU0, external 8 root memories of CPU1, totally 6 of PCIE slot.
