Embodiment
Emphasis of the present invention is the layout circuit on a transition card, makes it to dispose two as central processor (CPU) among socket 370 forms, can have the structure of two CPU on the motherboard that slot 1 slot is generally only arranged thus.Because two CPU are configured on the single transition card, the configuration that the transmission of its clock signal, the conversion of voltage and two CPU go up between the pin on same pin and the corresponding transition card golden finger (gloden finger) just seems very difficult, and must be designed especially.In addition, identical in the drawings symbology components identical.
Please refer to Figure 1A and Figure 1B, it illustrates on the transition card with bi-processor architecture of the present invention, the possible connection diagram between the corresponding golden finger circuit on corresponding wherein this pin and the transition card between two processor sockets.Transition card 10 has a plurality of electrical pins, and golden finger circuit 12 as shown in the figure inserts the microprocessor slot (slot) that is positioned on the motherboard by it, and for example the slot of slot 1 specification makes it to electrically connect with motherboard.
On transition card 10, dispose first and second processor socket (socket) 14a, 14b.First and second processor socket 14a, 14b can be the socket as socket 370 specifications.Connecting hole (pin holes) is arranged on processor socket 14a, the 14b, and its pin (pin) with processor is consistent, can make the processor installing thereon.When using identical socket, because of the pin and the pin of same position on microprocessor and socket are represented transmission or received identical signal with processor.Because two processors are configured on the transition card 10, and the golden finger circuit 12 on the transition card 10 is only at the design of single-processor, therefore, just must be connected to simultaneously on two processor socket 14a, the 14b on the corresponding with it pin when the part pin in the golden finger circuit 12 on the transition card 10.Simultaneously, same position also must connect in order to the pin that transmits or receive identical signal on socket.
With reference to Figure 1A and Figure 1B, this figure is with one of them the pin 12a in the golden finger circuit 12, and the synoptic diagram that may connect up of annexation between two pin 16a, 16b that processor socket 14a, 14b are last and pin 12a is corresponding two.The thing of noting, this figure just illustrates notion usefulness, is not the practical wiring that the present invention implements in reality.
In order to finish the transition card with bi-processor architecture of the present invention, its wire laying mode system adopts for example mode of daisy chain (daisy chain), that is links components identical (is pin on processor socket 14a, the 14b at this) on the same signal wire 18.Secondly, higher quality is arranged, must form pull-up resistor (pull-up resistor) Rs in the terminal of pin in order to reach signal wire 18.This pull-up resistor Rs connects a terminal voltage (terminal voltage) VTT at last again, as 1.5V.Pull-up resistor Rs can be designed to 56 ohm, forms a kind of transmission line of GTL form.Secondly, this pull-up resistor Rs must be less than 1 inch with the signal wire length L as this processor socket 14b at pin (example at this figure the is pin 16b) place of terminal.
The pull-up resistor of each signal wire is not all in the side of the second processor socket 14b.Actual cloth line position must the situation when practical wiring come the layout on the transition card 10 is done optimized consideration.
When design had the transition card of bi-processor architecture, second factor that must consider was the clock signal of supply processor work.Because make the processor can synchronous operation, deliver to the clock signal that is installed in the processor on first and second processor socket 14a, the 14b and just must give processor simultaneously and can not postpone each other.Yet, a clock generator is only arranged on the motherboard that has only a slot, therefore for head it off, just must configuration zero-lag clock buffer (zero delay buffer) on transition card 10.
Please refer to Fig. 2 A and Fig. 2 B, it illustrates configuration synoptic diagram possible between zero-lag clock buffer and the processor socket.Zero-lag clock buffer 20 is configured in the appropriate location on the transition card 10, and the clock from the golden finger circuit 12 of transition card 10 receives the clock signal of pin position 12b reception from motherboard.Afterwards, simultaneously clock signal clk 1 is delivered to the last corresponding pin of processor socket 14a, 14b with CLK2 by zero-lag clock buffer 20 again.When designing wiring, do not have phase delay in order to reach clock signal clk 1 really with CLK2, the distance of the pin of last correspondence must be isometric from zero-lag clock buffer 20 to each processor socket 14a, 14b; Draw the signal wire FBCLK of a feedback as shown in the figure simultaneously.And its actual configuration is familiar with this skill person and can be finished in various feasible modes easily.In like manner, (advanced peripheralI/O control, APIC) clock signal also can utilize above-mentioned method to reach the purpose of clock signal zero-lag in senior peripheral hardware input and output control.APIC control peripheral hardware can be used for controlling the control that what person should move between two processors.
Transition card with bi-processor architecture of the present invention, one of its purposes are generally only to have on the motherboard of single slot 1 specification slot, use the processor of two socket 370 specifications.The processor of socket 370 specifications except core voltage (core voltage, Vcore) outside, need to provide the voltage of 2.5V in addition.Yet, on general this kind slot 1 specification slot, do not provide this voltage, the next purposes as voltage transitions of voltage regulator (voltage regulator) therefore just must be arranged on transition card 10.
Please refer to Fig. 3 A and Fig. 3 B, it illustrates configuration synoptic diagram possible between voltage regulator and the processor socket.Voltage regulator 22 is disposed at the appropriate location on the transition card 10, in order to voltage transitions is become to be installed in the required operating voltage of processor on first and second processor socket 14a and the 14b.In this example, voltage regulator 22 can use the linear regulator of a 5V-2.5V.
The core voltage of voltage regulator 22 from the golden finger circuit 12 of transition card 10 receive pin position 12c receive from motherboard+5V voltage.Afterwards, become the voltage of 2.5V again by voltage regulator 22 general+5V voltage transitions, in order to deliver to the last corresponding pin of processor socket 14a, 14b respectively.
Last in order to make motherboard can support the function of dual processor, only need the content of basic input/output system upgraded and just can.To sum up, according to the transition card with bi-processor architecture of the present invention, it can use dual processor at general single slot motherboard, particularly uses the processor of two socket370 specifications.
In sum, though the present invention be described with preferred embodiment, yet be not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention, can carry out various modifications and improvement, so protection scope of the present invention is defined by the appended claims.
