Embodiment
With reference to the accompanying drawings, embodiment of the present utility model is described in detail.
Fig. 1 illustrates the structured flowchart of an embodiment of foundation online burning of the present utility model system.With reference to Fig. 1, this system comprises control module 10 and burning/ recording chip 14,16 and 18 at least.Wherein, burning/ recording chip 14,16 and 18 correspondingly has three burning interfaces (label is respectively 141,161 and 181) and three EEPROM (label is respectively 143,163 and 183) respectively.In other words, burning/recording chip 14 comprises burning interface 141 and EEPROM143, and burning/recording chip 16 comprises burning interface 161 and EEPROM163, and burning/recording chip 18 comprises burning interface 181 and EEPROM183.In this embodiment, for example, burning/recording chip 14 is a network interface card, and burning/ recording chip 16 and 18 is 8648 integrated chips.In addition, burning interface 141,161 and 181 shown in Figure 1 is a jtag interface.In one embodiment of this invention, this online burning system can also comprise connector 12.Correspondingly, connector 12 is used to electrically connect control module 10 and outside burning equipment (not shown), when any one EEPROM among the online burning EEPROM143,163 and 183, outside cd-rom recorder comes the EEPROM of burning correspondence via connector 12 and control module 10.
Those of ordinary skill in the art is to be understood that, online burning system shown in Figure 1 is a specific embodiment of the present utility model, be intended to describe the circuit framework and the technical scheme of carrying out online burning at two or more EEPROM, be confined to this but have more than.For example, this system can only comprise two burning circuit with two EEPROM, perhaps also can comprise to have the burning circuit more than three that surpasses three EEPROM.In the present embodiment, control module 10 is a CPLD.
In the online burning system of Fig. 1, JTAG connects 141,161 and 181 and all electrically connects with control module 10.By the control end of control module 10, receiving an input voltage and just switching online programming system, so that can realize the online burning of a slice EEPROM arbitrarily among three EEPROM in section sometime according to the level of this input voltage.For example, this control end is an input pin of CPLD.In a sense, the control end of control module 10 is equivalent to treat that the EEPROM of burning carries out the enable signal end of online burning, for example, when high level is effective, online burning EEPROM143, when low level is effective, online burning EEPROM163 or EEPROM183 accordingly.The control end that should be appreciated that control module 10 of the present invention can also be a plurality of input pins, and when the quantity of this input pin was N, the EEPROM quantity of online burning in the online burning system can reach 2
N(N is the natural number greater than 1).
Below describe the inner structure of the control module 10 be used for realizing multi-disc EEPROM online burning in detail.Fig. 2 illustrates the part immanent structure synoptic diagram of control module 10 in as shown in Figure 1 the online burning system.
With reference to Fig. 2, control module 10 comprises three I/O interfaces (number in the figure is respectively 101,103 and 105), link block 107 and control end 109.I/O interface 101 electrically connects jtag interface 141, and I/O interface 103 electrically connects jtag interface 161, and I/O interface 105 electrically connects jtag interface 181.Link block 107 is electrically connected to connector 12, is used as the data transmission interface between control module 10 and the connector 12.In one embodiment, each I/O interface is corresponding to a plurality of universal input and output port of control module 10, and link block 107 and control end 109 are also corresponding to a plurality of universal input and output port of control module 10.
Those of ordinary skill in the art should be appreciated that comprised in the control port quantity of control end 109 and the system treat that burning EEPROM number is closely related.For example, when system had two EEPROM that treat burning, control end only needed an input pin just connector 12 can be switched to electrical couplings in another jtag interface from electrical couplings in a jtag interface.When system had four EEPROM that treat burning, control end just needed two input pins control to switch corresponding online burning EEPROM.
In conjunction with Fig. 1 and Fig. 2, for example, when two in the control end 109 input pins were followed successively by " 0 ", " 0 ", connector 12 electrical couplings were to jtag interface 141, and system begins online burning EEPROM143; When two in the control end 109 input pins were followed successively by " 0 ", " 1 ", connector 12 electrical couplings were to jtag interface 161, and system begins online burning EEPROM163; And when two in the control end 109 input pins were followed successively by " 1 ", " 0 ", connector 12 electrical couplings were to jtag interface 181, and system begins online burning EEPROM183.Certainly, respectively the importing level state between the pin and can also adopt other logical combination of control end 109, switch connector 12 and be electrically connected to jtag interface 141 or jtag interface 161 or jtag interface 181, with online burning EEPROM143,163 and 183 accordingly.
In addition, it is to be noted, in structure shown in Figure 1, though jtag interface 141 electrically connects with network interface card 14, jtag interface 161 and 8648 integrated chips 16 electrically connect, and jtag interface 181 and 8648 integrated chips 18 electrically connect, but the interface of jtag test standard includes following four ports, that is, selecting side, clock end, data input pin and data output end.That is to say, which EEPROM of online burning no matter, the plurality of terminals in the connector 12 is all corresponding to defined selecting side, clock end, data input pin and data output end in the jtag test standard.
Adopt online burning of the present utility model system, by introducing control module, thereby make each treat jtag interface time-sharing multiplex connector in the burning/recording chip, successfully to realize the burning of each EEPROM such as CPLD.In addition, this online burning system need not to increase hardware cost, also can save manpower and time, reduces off-line burning operation, significantly improves efficient.
Above, describe embodiment of the present utility model with reference to the accompanying drawings.But those skilled in the art can understand, and under the situation that does not depart from spirit and scope of the present utility model, can also do various changes and replacement to embodiment of the present utility model.These changes and replacement all drop in the utility model claims institute restricted portion.
