The present invention's a kind of " dual-memory data transmission method " is characterized in that, comprises the following steps:
(1) computer is exported a reward for writing or painting and is expected storer A;
(2) if finished output, and if computer during the no data transmission, then storer A output data is printd to the controller of prining, finish print after i.e. end data transmit; If when computer still has the data transmission, promptly enter next step;
(3) storer A output data is printd to the controller of prining, and the while computer is exported another reward for writing or painting and expected storer B;
(4) if finish output respectively, and if computer during the no data transmission, then storer B output data is printd to the controller of prining, finish print after the transmission of i.e. end data: if when computer still has data to transmit, promptly enter next step;
(5) storer B output data is printd to the controller of prining, and the while computer is exported another reward for writing or painting and expected storer A; Enter step (2) again.
Wherein storer A and storer B are linear memory.
Other purposes of the present invention, effect and embodiment see also graphic being described in detail as follows, wherein:
Fig. 1 is the block schematic diagram of the mode of generally prining.
Fig. 2 is for using the block schematic diagram of the mode of prining of the present invention.
Fig. 3 is a structure calcspar of the present invention.
Fig. 4 is data transfer process figure of the present invention.
Seeing also shown in Figure 2ly, use the mode of prining of dual-memory data transmission device of the present invention and method, mainly is with linear memory A61 and the mutual transmission of the linear memory B62 data of prining; When computer 1 via import/go out interface 2, data processor 4 has passed rows of seal data to linear memory A61, linear memory A61 is about to this row data and reaches the controller 7 of prining, and passes to column print head 8 again and controls column print head 8 work of prining; On-line memory A61 transmission data is to the controller 7 of prining, when column print head 8 is printd, and computer 1 can be printd data transmission to linear memory B62 with next column via importing/go out interface 2; The data output that stores as linear memory A61 is also printd and is finished, and after linear memory B62 received rows of seal data, computer can transmit rows of seal data again to linear memory A61, and isochrone storer B62 output data to the controller 7 of prining is printd; Linear memory A61 and linear memory B62 can continual mutual reception from the data of prining of computer 1, and the continual mutual transmission data of prining is printd to the controller 7 of prining, column print head 8; So can carry out the two-way transmission operation of data input/go out simultaneously, the efficient of obviously lifting data transmission; Use the present invention again and can cancel the configuration of the page memory of larger capacity, also escapable cost.
See also shown in Figure 3ly, primary structure of the present invention comprises that a processor 9 connects and imports/go out controller 91, data processor 4, many merits controller A92, many merits controller B93, print controller 7 and motor controller 94; Wherein importing/go out controller 91, data processor 4, many merits controller A92 is connected in regular turn; Many merits controller A92 is connecting line storer A61 and linear memory B62 respectively; The other end of linear memory A61 and linear memory B62 connects many merits controller B93: many merits controller B93, print controller 7 and column print head 8 are connected to each other in regular turn.When importing/go out controller 91 outputs one row data after data processor 4 processing, processor 9 is promptly controlled many merits controller A92 will speak of data mutual incoming line storer A61 or linear memory B62, processor 9 many merits of control controller B93 output to the controller 7 of prining alternately with linear memory A61 or the linear memory B62 that is filled with a row data simultaneously; Control column print head 8 was printd after the controller 7 of prining will the data of prining be converted to the form of prining, and after column print head 8 had been printd a permutation, processor 9 was promptly controlled the motor controller 94 CD-ROM drive motor drive material of prining and moved to next column, so that print.
See also shown in Figure 4ly, data transmitting step of the present invention is as described below:
(1) computer is exported a row data to storer A;
(2) if finished output, and if computer during the no data transmission, then storer A output data is printd to the controller of prining, finish print after i.e. end print; If when computer still has the data transmission, promptly enter next step;
(3) storer A output data is printd to the controller of prining, and computer is exported another row data to storer B simultaneously;
(4) if finish that these row are printd respectively and data output, and if computer during the no data transmission, then storer B output data is printd to the controller of prining, finish print after i.e. end print; If when computer still has the data transmission, promptly enter next step;
(5) storer B output data is printd to the controller of prining, and computer is exported another row data to storer A simultaneously; Enter step 2 again.
The present invention utilizes linear memory A and linear memory B, cooperate many merits controller A and many merits controller B under the control of processor, has the function that data was exported/gone in mutual adjustment, can carry out the input of data and can reach when exporting data column print, the storage device that can reach with minimum reaches the fastest transfer efficiency.Computer among Fig. 4 can be physical data treating apparatus A, and the controller of prining also can be physical data treating apparatus B, utilizes the present invention to carry out the transmission of data.
Above record person only for utilizing the embodiment of the technology of the present invention content, anyly is familiar with modification, the variation that this skill person uses the present invention to do, the claim that all belongs to the present invention and advocated.
In sum, dual-memory data transmission device of the present invention and method, the transmitted in both directions operation that can import simultaneously and export has broken through the one-way transmission mode that general page memory only can input or output in conjunction with a linear memory, and real is an innovation greatly of data transmission technology; And the present invention reaches transfer rate faster with less capacity storage device, and more the physical data transmitting device has closed in the patent of invention important document can't be obtained in fact.
