Description
Technical field
The present invention relates to a kind of method of parallel programming, relate in particular to a kind of method that adopts multiplexing technique to carry out parallel programming.
Background technology
In the prior art, the primary structure of chip burn-recording system has two kinds of serial programming system and parallel programming systems, and the serial programming system can be divided into the programming system of the serial same kind chip of man-to-man serial programming system and one-to-many again.
Described man-to-man serial method for burn-recording, promptly a controller is finished the burning to a kind of chip in the specific time.When adopting this programming system, controller can only be realized the serial burning to chip, as the need parallel programming, then must adopt many controllers, utilizes the mode of equivalent superposition to carry out the burning operation, just can realize the parallel programming to chip.
The method for burn-recording of the serial same kind chip of described one-to-many, promptly controller can carry out burning by the chip to a plurality of same kind one by one by the switching of electronic switch in special time period; Also can utilize the characteristic of bus to carry out the switch switching, to finish the burning chip of one-to-many at the bus waiting time.When adopting this programming system, controller can only be realized the burning to the chip of bus type of the same race at one time in the section, as the burning of needs realization, then need many controllers to carry out the operation of burning in the mode of equivalent superposition equally to the chip of different bus type.
An above-mentioned controller can only be realized the burning to the chip of single chip or bus type of the same race; And when carrying out the chip of different bus type during burning, need many controllers to operate simultaneously.Therefore, when chip burn-recording system of the prior art and method are carried out burning at the chip to the different bus type, there is the defective of time-consuming or waste hardware.
Summary of the invention
For solving above-mentioned middle problem and the defective that exists, the invention provides a kind of method that adopts multiplexing technique to carry out parallel programming.
The present invention is achieved by the following technical solutions:
A kind of method that adopts multiplexing technique to carry out parallel programming involved in the present invention comprises: a transfer bus bandwidth is divided into different frequency ranges; The data that control end transmitting control commands and control carry the specified type bus signals are transmitted in the designated frequency band of described transfer bus; The burning termination is received the data of transmission in the described designated frequency band, and described data parallel is burnt on the chip of specifying bus type.
Described burning termination is received the signal of the chip institute feedback of described appointment bus type, and the signal of described chip institute feedback is returned to control end.The signal of the chip institute feedback of the described appointment bus type that described burning termination is received is modulated to the signal of the peculiar identifying information that has described chip; The data demodulates of transmission becomes the burning of described chip can recognition data in the described designated frequency band that described burning end will receive.Described control end becomes the described data-modulated that carries different specified type bus signals can become the data that can transmit simultaneously in the data-modulated of the identical or different specified type bus signals of one of described transfer bus in the identical or different designated frequency band of one of described transfer bus; The signal of the chip institute feedback of the described appointment bus type that described control end will be sent from described burning end is demodulated to the information that described control end can be discerned.
The beneficial effect of technical scheme provided by the invention is:
Be controlled at the same time of same transfer bus by a controller unit chip of multiple different bus type is carried out burning, thereby reach under the condition of economize on hardware resource, the chip of carrying out different types fast carries out the beneficial effect of parallel programming, both saved recordable time, also improved dirigibility simultaneously variety classes chip ambition burning operation to the variety classes cake core.
Description of drawings
Fig. 1 adopts multiplexing technique to carry out the method flow diagram of parallel programming.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing:
Present embodiment provides a kind of method that adopts multiplexing technique to carry out parallel programming.
Referring to Fig. 1, this method mainly may further comprise the steps:
Step 100 start-up control end and operation.
The bandwidth of transfer bus is divided into different frequency ranges, and transmitting control commands and carry the data of specified type bus signals.
The data-modulated that step 101 control end will carry different specified type bus signals becomes the data that can transmit simultaneously in the identical or different designated frequency band of one of transfer bus, and the data after will modulating are transferred to a plurality of burning ends by designated frequency band.
After step 102 is received the data of transmission in the designated frequency band with 102 ' each burning termination, judge whether the data after ovennodulation that receive meet the feature modulation type of this burning end self.
If do not meet, then continue execution in step 102 and 102 ' until the data that receive the feature modulation type that meets this burning end self, if meet, execution in step 103.
The data demodulates through after the ovennodulation that step 103 and 103 ' will receive becomes the objective chip of each different bus type can recognition data when burning.
Step 104 and 104 ' is carried out the burning operation to the objective chip of each different bus type.
So that the data parallel after the demodulation is burned onto each objective chip.
After step 105 and 105 ' treated that each objective chip burning is finished, the signal of the objective chip institute feedback of each different bus type that each burning end will receive carried out the feature modulation.
Be modulated to the signal of the peculiar identifying information that has each objective chip with signal, and the signal of each objective chip institute feedback that will be after ovennodulation returns to control end with each objective chip institute feedback.
The signal of the objective chip institute feedback of each different bus type after ovennodulation that step 106 control end will be sent from each burning end is demodulated to the information that control end can be discerned according to the peculiar identifying information of each objective chip.
Execution in step 100 then, operate to carry out follow-up burning, and then finish the more parallel programming operation of a different bus type objective chip.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
