Description of the invention: . [Technical field to which the invention pertains] - The present invention relates to a multiple load topology architecture. [Prior Art] The development of electronic technology has made the working speed of integrated circuits faster and faster, and the working frequency is getting higher and higher. The load on the design is more and more, so the designers often need to design them. - The signal control terminal is connected to two or more wafers 'for providing signals to the two or more chips. Referring to FIG. 1 , a multi-load topology architecture of the prior art includes a signal control terminal 10 and five receiving terminals 2 〇, 3 〇, 40, 60 ′ where the signal control terminal 10 and the five receiving terminals 2 〇, 3〇, 4〇, 5〇, and 60 are connected by a topological architecture, which includes four connection points eight, B, C, and D. In this architecture, the driving signal is sent from the signal control terminal 1 to the receiving end along the transmission line. Since the receiving ends are unevenly distributed, the signal from the signal control terminal 10 reaches the receiving end. The long-term production of the wheel will be different, and there is a delay of the transmission line for each distance of the drive signal. If the length difference between the two transmission lines is greater than the product of the signal transmission speed of the driving signal and the signal rise time, The signal received by the receiving end connected to the S transmission line will be significantly different. Meanwhile, since the distance between the receiving ends is different, the reflected signal of the far receiving end will be reflected to other nearby receiving ends. Therefore, the signals received by the receiving end close to the rut are superimposed, which causes the waveform to generate a non-monotonic phenomenon during the last 200929864 liter, which affects the integrity of the signal and its function, resulting in timing. And digital operation error. • Please continue to refer to FIG. 2 , which is a simulation waveform diagram of the signals received by the receiving ends in FIG. 1 , wherein the signal curves 22 , 33 , 44 , 55 , and 66 correspond to the receiving ends 2〇, 3〇, 4〇, respectively. The signal simulation curves of 5〇 and 6〇, we can see from Figure 2 that the signal simulation curves 22 and 33 corresponding to the receiving ends 20 and 30 generate severe non-monotonic phenomena during the rising period, which may affect the signal. Integrity is more likely to cause timing and digital bit errors. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a multi-load topology structure for reducing the non-monotonicity of signals received by the receiving end to improve the stability of the system operation. A multi-load topology structure includes a signal control terminal for transmitting a driving signal, the signal control terminal is connected to a first connection point through a transmission line, and the first connection point is respectively connected to a first reception via two transmission lines And a second connection point, a length of the transmission line between the first receiving end and the first connection point is greater than a length of a transmission line between the second connection point and the first connection point, and a first resistor is connected a transmission line between the first connection point and the first receiving end. In the multi-load topology architecture of the month, the first resistor can attenuate the noise signal strength entering the first receiving end, improve its excessive reflection phenomenon, and ensure the integrity of the signal received by the first receiving end to ensure stable operation of the system. [Embodiment] 200929864 Referring to Figure 3, a preferred embodiment of the multiple load topology architecture of the present invention includes a signal control terminal 100, five receiving terminals 200, 300, 400, 500, 600' resistors ^ "factory" ^ And a plurality of transmission lines, wherein the signal control terminal 100 is connected to the five receiving ends 200, 300, 400, 500, and 600 by a daisy chain topology, and the signal control terminal is connected to a first connection point through a transmission line. E, the first connection point is respectively connected to the receiving end 200 and a second connecting point F via two transmission lines, and the first connection point F is respectively connected to the receiving end 3〇〇 and a third connecting point G through two transmission lines. The third connection point G is connected to the receiving end 400 and a fourth connecting point η through two transmission lines respectively, and the fourth connection point H is respectively connected to the receiving ends 5 〇〇 and 6 透过 through two transmission lines. The receiving end 4 is a Debug device, which is only used to assist in detecting the content of the transmission protocol, and has no data transmission function, and the receiving ends 200, 300, 5, and 600 are all blamed. The receiving end of the transmission function. In the above-described chrysanthemum structure, the length of the transmission line 该 between the receiving end 200 and the first connection point e is greater than the length of the transmission line between the second connection point F and the first connection point E, and the resistance RS1 is connected thereto. a transmission line between the first connection point E and the receiving end 200; a length of the transmission line between the second connection point F and the third connection point G is greater than a transmission line between the second connection point F and the receiving end The length of the transmission line is connected to the transmission line between the second connection point F and the third connection point G; the length of the transmission line between the fourth connection point Η and the first connection point G is greater than the length of the receiving end a length of the transmission line with the third connection point G; a length of the transmission line between the fourth connection point η and the receiving end 600 is greater than a length of the transmission line between the fourth connection point η 200929864 and the receiving end 500 The resistor rs3 is connected to the transmission line between the fourth connection point and the receiving end 6〇〇. In the multi-load topology, the driving signal is sent from the signal control terminal 100 to the receiving ends 200, 300, 400, 5, and 600 along the transmission line. At this time, the resistor RS1 can attenuate the signal strength entering the receiving end 200, thereby improving the signal strength. Excessive reflection phenomenon, the resistor RS2 boosts the non-monotonic voltage level entering the receiving terminal 300, so that the voltage level is higher than the threshold voltage, and the ❹ resistor RS3 reduces the overshoot phenomenon at the receiving end. In the above multiple load topology, connecting the resistors RS1, RS2 and RS3 enables the quality of the signals received by the receiving terminals 2, 300 and 600 to be improved, thereby avoiding non-monotonic phenomena and ensuring the stability of the system operation. ♦ Please continue to refer to FIG. 4 , which is a waveform diagram for performing simulation verification on signals received by multiple loads in the multiple load topology architecture of the present invention, wherein the signal curves 222 , 333 , 444 , 555 , and 666 respectively correspond to the receiving ends 200 , 300 , The signal simulation curves of 400, 500 and 600, as can be seen from Fig. 4, 'the signal waveforms received by the receiving ends 200 and 300 are not monotonous, and the signals received by other receiving ends have no obvious non-monotonic phenomenon. . Since the receiving end 400 is a debugging device, which is only used to assist in detecting the content of the transmission protocol, the non-monotonic phenomenon of the received signal can be ignored, that is, the third connection point G and the fourth connection point η are not needed. Another resistor is provided to enhance the signal strength entering the receiving end 400, thereby reducing the amount of resistance used in the entire daisy-chain topology, which saves cost' and also reduces the delay time of signals arriving at each receiving end. The foregoing embodiment takes a five-branch circuit and four connection points as an example. 200929864
