Chip embodiment
See Fig. 2, the present embodiment provides a kind of carbon powder box chip 20, comprise: substrate 21 and communication unit on the base plate (21 and integrated circuit 22 are set, said structure is identical with the structure of existing ink box chip 10 or carbon powder box chip, and difference is: the integrated circuit 22 of the carbon powder box chip 20 of the present embodiment comprises: memory cell, interface unit, control unit, read-write control unit, temporary storage unit, buffer memory unit and SP.
As shown in Figure 3, interface unit provides interface for chip and printer communication; Temporary storage unit comprises 32 groups of Data buffer and 32 group address buffers, preserves data message or the address information of printer transmission for dividing into groups respectively; SP comprises some stack pointers, and it is for locating above-mentioned temporary storage unit; Buffer memory unit is connected with temporary storage unit and memory cell respectively, comprises data buffer and Address Register, for preserving data message or the address information of the transmission of above-mentioned temporary storage unit respectively; Memory cell comprises nonvolatile memory EEPROM, this memory cell, for storing the information relevant to cartridge, consumes number of print pages as carbon dust surplus in cartridge plant code, cartridge date of manufacture, cartridge model, characterisitic parameter, toner color, cartridge, the initial print time, upper one of cartridge prints the data messages such as operating time; Control unit is connected with said memory cells, interface unit, temporary storage unit and buffer memory unit respectively, for controlling the data manipulation of said memory cells, interface unit, temporary storage unit and buffer memory unit; Read-write control unit is connected with above-mentioned temporary storage unit, memory cell, control unit and SP respectively, after data for controlling one 32 groups in temporary storage unit are all written to EEPROM with the principle of " FIFO " by buffer unit, just perform the operation of next 32 groups, and when printer reads the content in EEPROM, suspend and data write operation is carried out to it.
See Fig. 4, Fig. 5, printer is when writing data to this carbon powder box chip 20, only need to send data message and address information to this carbon powder box chip 20 continuously, data message and the address information of 32 bytes can be transmitted at most continuously, carbon powder box chip 20 is after the data message receiving write order and first character joint and address information, first data message is saved in the first Data buffer group, address information is saved in the first address register group, stack pointer adds 1, then data message is sent to data buffer, address information is sent to Address Register, to start, the data of EEPROM are write, carbon powder box chip 20 continues the write data message receiving printer transmission simultaneously, second byte data is preserved in second group of Data buffer group, stack pointer adds 1 again, the like, until when stack pointer number is 31, carbon powder box chip 20 no longer receives data, when carbon powder box chip 20 couples of EEPROM complete the data write operation of a byte, stack pointer subtracts 1, control unit differentiates whether stack pointer is zero, if stack pointer number is zero, show that data message in temporary storage unit and address information are all transferred to EEPROM from buffer memory unit, control unit no longer performs the write operation to EEPROM, answer signal is sent to represent that all data have write to printer, if stack pointer number is non-vanishing, data message in second group of Data buffer is then transferred in first group of Data buffer by control unit, data message in 3rd group of Data buffer is transferred in second group of Data buffer, the like, address information in address register also moves as described above, complete after moving, data move to EEPROM from temporary storage unit through buffer memory unit by the principle continued according to " first in first out ", until all byte datas in 32 bytes all write in EEPROM, now, this carbon powder box chip 20 could continue the data write operation starting a new round.Therefore, when the carbon powder box chip 20 provided the present embodiment writes data, do not need every byte all to wait pending data to be written in EEPROM, printer or chip controls unit just can do other work during storage chip writes data into EEPROM.
Fig. 6 shows the data of reception and the principle relation between preservation position, address and stack pointer: if current stack pointer is zero, when to write buffer enable signal WR_r be high level pulse, WR1 is high level pulse, data and address are just written in first group of data and address register, and other write signal is low level pulse; If current stack pointer is 32, when to write buffer enable signal WR_r be high level pulse, WR32 is high level pulse, data and address are just written in the 32nd group of data and address register, other write signal is low level pulse, so, stack pointer just determines the address of write registers.
In the process of data write EEPROM, if printer or chip controls unit need to read data from EEPROM, read-write control unit can suspend write operation to EEPROM by control EEPROM, then, the data address of required reading is sent to Address Register, and send read signal RD to EEPROM, so, just data can be read from EEPROM; After digital independent completes, the data in the first group address buffer can be sent in Address Register by read-write control unit, the write operation then to data from the address stopped is continued.
One as chip embodiment of the present invention converts, and can deposit the data of arbitrary integer group in 1 ~ 31 in temporary storage unit and buffer memory unit, as deposited 10 groups of data, this conversion equally also can realize object of the present invention.
As another conversion of chip embodiment of the present invention, read-write control unit when EEPROM reads data, can not suspend the data write operation to EEPROM, and this conversion equally also can realize goal of the invention of the present invention.
Chip data wiring method embodiment
The chip data wiring method that the present embodiment provides is applied to the chip described in said chip embodiment, concrete grammar is: temporary storage unit receives data message and the address information of 32 bytes continuously, pass through SP simultaneously, data message corresponding in 32 bytes and address information are transferred to data buffer and Address Register respectively according to the principle of " FIFO ", with the principle simultaneously according to " FIFO ", the data message in data buffer and the address information in Address Register is write in EEPROM; When 32 bytes all write EEPROM, temporary storage unit just receives the information of next round 32 bytes; When EEPROM is in the process of data write, when printer or chip controls unit read data from EEPROM, read-write control unit suspends the data write operation to described nonvolatile memory, send read signal and read address to described buffer memory unit to described nonvolatile memory, transmission, after completing digital independent, data in the first group address buffer are sent to Address Register to continue write operation.
Specific procedure operating procedure is as shown in Fig. 7-a and Fig. 7-b:
S10: start;
S20: it is read signal or write signal that read-write control unit judges? if read signal, then enter step s201, if write signal, then enter step s30; First read-write control unit judges that signal is read signal or write signal, and carries out follow-up corresponding read operation or write operation respectively according to judged result;
S201: judge whether to write? if so, then step s202 is entered, otherwise, enter step s206; This step judges whether just to carry out write operation to EEPROM, if carry out write operation to EEPROM, read-write control unit sends the order stopping write, if EEPROM does not carry out write operation, then direct from EEPROM reading information;
S202: stop write operation;
S203: by the address into address buffer of read data;
S204: start read signal;
S205: after running through, is sent to Address Register by the address information in the 1st address register, then enters step s322;
S206: by the address information writing address buffer of read data;
S207: after starting read operation, enter step s328;
S30: judge that address pointer is zero? if be zero, then enter step s320, otherwise, enter step s310; According to the value of address pointer, data message and address information are stored in corresponding Data buffer and address register with the principle of " first in first out ", pointer value is zero, then corresponding 1st group of Data buffer and address register, by that analogy, pointer value is 31, then corresponding 32nd group of Data buffer and address register;
S310: judge that address pointer is 1? if so, then step s3120 is entered, otherwise, enter step s3110; When the value of stack pointer is 1, data message and address information are stored in the 2nd group of buffer, when stack pointer is not 1, continue to judge whether the value of pointer is 2 ... until judge whether pointer is 31;
S3110: judge that address pointer is 2? if not, enter step s3111, if so, then enter and follow-uply deposit step; The same, when the value of stack pointer is 2, be similar to the operation of step s3120 ~ s3122, data message and address information be stored in the 3rd group of buffer, when stack pointer is not 2, continue to judge whether the value of pointer is 3 ... until judge whether pointer is 31;
The step of s3111 ~ s31128 is similar to s310, s3110, all whether equal 3 ~ 30 to the value of pointer successively to judge, if not, then enter next to judge, if so, be then stored in the buffer corresponding to address pointer by data message and address information, value is 3, then be stored in the 4th group of buffer, by that analogy;
S31129: judge that address pointer is 31? if so, then step s31131 is entered, otherwise, enter step s328;
S31131: data message and address information are saved in respectively the 32nd group of Data buffer and the 32nd group address buffer, then enter step s3122;
S3120: data message and address information are saved in respectively the 2nd group of Data buffer and the 2nd group address buffer;
S3121: stack pointer adds 1;
S3122: wait for that first character joint number is according to after write, enters step s323;
S320: data message and address information are saved in respectively the 1st group of Data buffer and the 1st group address buffer;
S321: stack pointer adds 1;
S322: start write operation; After the data message of the 1st byte and address information are stored in corresponding data buffer and address register, start write operation at once, namely be data message and address information are transferred to data buffer and Address Register from Data buffer and address register, to realize the write operation to EEPROM;
S323: one time write operation completes, and stack pointer subtracts 1; After the whole write registers of information of one group of 32 byte, stack pointer progressively subtracts 1, until stack pointer is zero, then shows that the data in buffer have been transferred in EEPROM completely;
S324: judge that pointer is zero? if be zero, then enter step s327, otherwise, enter step s325;
S325: successively data message and address information are transmitted toward the front portion of Data buffer and address register; Successively the data message in buffer and address information are moved forward, until move to first;
S326: start write operation, enter step s323;
S327: send write operation and complete answer signal; Complete the write of one group of 32 byte;
S328: terminate; Terminate this and take turns write operation.
When printer reads data to this carbon powder box chip, or control unit from EEPROM read data time, first read signal pulse RD is sent to read-write control unit, after read-write control unit detects RD pulse signal, first judge whether to there is the write operation to EEPROM, if there is no write operation, then first by the address into address buffer of read data, then start the read operation to EEPROM; If there is write operation, then first can stop the write operation to EEPROM, by the address into address buffer of read data, and then the read operation started EEPROM, after read operation completes, first group address scratch memory data is sent to Address Register, to recover former write operation address, then continues the write operation process started above; Because the time of read data is generally at about 100ns, and the time writing data is in Millisecond, therefore writes interrupt logarithm very small according to write impact.
Printer writes 32 groups of data continuously, EEPROM read-write control unit is after first write pulse being detected, can first group of data (32bits) be written in the 1st group of Data buffer, address is written in the 1st group address buffer simultaneously, then the 1st group of data and address register data are sent in data buffer and Address Register, then start write operation, then stack pointer is added 1.Chip continues to receive the storage data that send over of printer, and by the 2nd group of data and address respectively stored in the 2nd group of data and address register, stack pointer adds 1 simultaneously; Then receive the 3rd group of data and address, and by the 3rd group of data and address stored in the 3rd group of data and address register, stack pointer adds 1 simultaneously; By that analogy, until receive whole 32 groups of data and address date, when stack pointer is 32, chip no longer receives data and address.
Read-write control unit completes after to an address date write, first address pointer can be subtracted 1, then differentiate whether address pointer is zero, namely the write to EEPROM of data whether has been had or not, if address pointer is zero, then think that data write all completes, answer signal can be sent to control unit or printer, represent that write all completes; If non-vanishing, then can data in the 2nd group of data and address register be sent in the 1st group of data and address register, and data are sent in the 2nd group of data and address register in the 3rd group of data and address register, by that analogy, in 32nd group of data and address register, data are sent in the 31st group of data and address register, then data in first group of data and address register are sent in data buffer and Address Register respectively, then write operation is started, circulation like this, until stack pointer is zero just no longer carry out write operation; In the process of write, as long as stack pointer is no more than 32, then storage chip just can receive write data and address, if storehouse is full, just again can receive data after then only writing into one group of data, its data write sequence is also that advanced person first writes, and writes after laggard.
Adopt this method, can make chip within the extremely short time, complete the write operation of data, that effectively avoids data to cause owing to not writing completely makes mistakes or loss situation, and, read-write control unit is after the data of the first round 32 bytes are written to nonvolatile memory completely, just allow the write operation carrying out next round 32 byte datas, ensure that the complete of data, prevent data from writing the error situation of chip processes.As: EEPROM data format is 32bits, and printer is maximum can send 32 groups of 32bits data and 1kbits continuously, can meet general data completely and store needs.
The address of said method embodiment write is continuous print, one as the chip data wiring method embodiment of the present invention converts, printer is when writing multibyte data continuously, its address can be arbitrary, as long as appointed by data format in advance, this conversion equally also can realize object of the present invention.
Another kind as the chip data wiring method embodiment of the present invention converts, and the byte that printer sends at every turn continuously can be 2 ~ 31, and be 32 bytes to the maximum, the byte number namely described in embodiment, above-mentioned conversion equally also can realize object of the present invention.
