Abstract
The invention proposes a method for fast writing a chip, which comprises the following steps: a first program code is prestored in a memory of a writer; a second program code and data are stored in the memory; the first program code is written into a microprocessor of the chip from the memory; power is supplied for the chip, thus causing the microprocessor to work; the first program code is executed and the data is written into a program control memory of the chip from the memory; and the second program code is written into the microprocessor from the memory to cover the first program code. The method can quicken the writing speed and improve the writing efficiency.
Description
Technical field
The present invention is relevant a kind of method for burn-recording, particularly relevant for a kind of method for burn-recording of chip.
Background technology
In driver chip, in the ROM (read-only memory) (ROM) of program designer with program code storage microprocessor (MCU) lining in chip, and the required data storing of this program code running equally also is being positioned at the electronics erasing type programmed read-only memory of chip (Electrically ErasableProgrammable Read-Only Memory; EEPROM) lining.Because the characteristic of EEPROM is only to accept MCU to do access with the instruction that reads or writes, therefore have higher security, but also make the program designer when EEPROM is carried out burning, it is very inconvenient that process becomes.
Fig. 1 illustrates the existing method that data is write EEPROM.Chip 16 is before burning program code not, MCU 12 can't move, also can not carry out access to EEPROM, when therefore the user will carry out burning program to chip, want earlier via burn recording software user interface setting, the ROM122 in the MCU 12 is advanced in the program code burning that can make MCU 12 that data are write into EEPROM 14 by cd- rom recorder 10,16 power supplies allow chip 16 work to chip chip 16 to be moved on to worktable again, this moment MCU 12 executive routine codes, the data that are included in the program code are write EEPROM 14, after pending data writes and finishes, stop chip 16 power supplies, chip 16 is connected with cd-rom recorder 10 once more, the user sees through the program code burning that will really want MCU 12 to carry out in the user interface again and advances ROM 122, override originally and can only do the program code that data write, finished burning program chip 16 to EEPROM 14.
Aforementioned program is for user's inconvenience very, because the user must write on data and allow MCU 12 be burnt to EEPROM 14 again in the program code of burning for the first time to carry out, if these data are to need process to judge that the data of decision or each chips are inequality, just the user must write different data at the program code of each chips.
Therefore, practical application needs a kind of compared with prior art method for burning chip more efficiently.
Summary of the invention
Purpose of the present invention is that the method that proposes a kind of fast writing chip solves the problem of burning inconvenience in the prior art.
According to the present invention, a kind of method of fast writing chip comprises and prestores one first program code in the storer of a cd-rom recorder, store one second program code and data and give this storer, with this first program code in the microprocessor of burned this chip of this storer, power supply allows this microprocessor work for this chip, carrying out this first program code writes these data in the program control storer of this chip from this storer, and with this second program code from burned this microprocessor of this storer, cover this first program code.
Beneficial effect of the present invention is: this method can be accelerated replication rate, improves burning efficient.

Embodiment
Make the purpose, technical solutions and advantages of the present invention clearer,, the present invention is described in further details below in conjunction with embodiment and accompanying drawing.At this, exemplary embodiment of the present invention and explanation thereof are used to explain the present invention, but not as a limitation of the invention.
Fig. 2 is the synoptic diagram of one embodiment of the invention, cooperates the process flow diagram of Fig. 3 to do explanation.Cd-rom recorder 20 a built-in random access memory (random access memory; RAM) 202, wherein there is the program code that makes MCU 22 can do read-write in advance to EEPROM 24, for convenience of description, below be referred to as first program code.In the time will carrying out burning to chip 26, carry out step 30, the user sees through the software interface input and really wants MCU 22 to carry out, can make chip 26 have second program code and the required data (data) of chip 26 work of complete function, carry out step 32 then, second program code and data are written into cd-rom recorder 20, be stored among the RAM 202, then, cd-rom recorder 20 beginning burning work, carry out step 34, first program code among the RAM 202 is burned to ROM 222, again to chip 26 power supplies, carry out step 36 and allow MCU 22 work, MCU 22 writes EEPROM 24 with the data among the RAM 202 again, at last, in step 38, cd-rom recorder 20 is burned onto ROM 222 with second program code from RAM 202 and overrides first program code, finish the program to chip 26 burnings, chip 26 has complete function.
The user need not write the data that will be burnt to EEPROM 24 in first program code, as long as second program code that exploitation is finished and the data that will be stored into EEPROM 24 are input to cd-rom recorder 20, can finish whole burning programs voluntarily by cd-rom recorder 20 and chip 26.If be burnt to the data difference of EEPROM 24, the user does not need to write again first program code, needs only the data of wanting in the software interface input of cd-rom recorder 20.
The person of ordinary skill in the field is can be unlabored impartial to be changed or scope that retouching all belongs to the present invention and advocated, and interest field of the present invention should be as the criterion with claims institute restricted portion.
