For this reason, utilize handwork will be connected to the equipment such as personal computer of computer program stored information the port (for example jtag port) of programmable logic device (PLD) traditionally, adopting the mode that downloads then.But, like this in the operation of each circuit board, one by one by manual operations when programmable logic device (PLD) downloads, exist the program complexity of operation, the problem that the activity duration becomes very long.
For this reason, need be a kind of in the circuit board operation of programmable logic device (PLD), can realize downloading automatically the scheme of programmable logic device (PLD) program.
Summary of the invention
The present invention develops in order to solve above-mentioned conventional art problem; It is a kind of in the circuit board operation that its purpose is to provide, and can download the devices and methods therefor of programmable logic device (PLD) program automatically.
Except above-mentioned purpose relevant of the present invention and strong point,, will can become clearer by following detailed description and accompanying drawing about other purpose and strong point.
The automatic programming unit of programmable logic device (PLD) of the present invention has following structure, is provided with storer that is:, wherein has the procedure code that will record in the programmable logic device (PLD); Be provided with control part, initial when drawing when system, it will remove to read the procedure code that leaves in the storer, and will record it in the programmable logic device (PLD).
Said apparatus also is provided with second memory, wherein has initialization identification id (ID (identity number)), promptly is used for display system at first from the specified data value of whether drawing.
In addition, above-mentioned when the system that normally finishes initial draw certainly the time, will go to upgrade initialization identification with the ID value.
The automatic programming method of programmable logic device (PLD) of the present invention has following step, that is: (a) is provided with when system draws at first certainly, goes to read the step that leaves the procedure code in the storer in; (b) be provided with the step that writes down the procedure code that is read to programmable logic device (PLD).
The initial of said system will be decided by from whether drawing whether the initialization identification id of depositing has initial value in storer.
In addition, the method for above-mentioned automated programming also is provided with a step, and promptly (c) is provided with one normally finishing the initial when drawing of system, goes to upgrade the step of initialization identification id value.
Advantageous effect of the present invention is as follows:
According to the present invention, in the circuit board operation of programmable logic device (PLD) is installed,, automatically be stored in the programmable logic device (PLD) because the program of programmable logic device (PLD) is initial when drawing in system, therefore the operation process of circuit board operation can be removed to simplify, and the ratio of handwork can be reduced.In addition, can also shorten the time of operation thus, enhance productivity.

Embodiment
Below, illustrate in greater detail example of the present invention with reference to accompanying drawing.
Fig. 1 is in example of the present invention, the automatic download apparatus structure in general figure of erasable programmable logical device program.
With reference to Fig. 1 as can be known, erasable programmable logical device Automatic Program download apparatus will comprise flash memory 10, control part 12, EEPROM14 and erasable programmable logical device chip 16.
The erasable programmable logical device Automatic Program download apparatus of Fig. 1 is mounted in electronic product, for example the part of the system on plasma TV or the liquid crystal TV set circuit board; In circuit board flow chart step, each inscape is electrically connected.
In flash memory 10, there is application code (application code), draw sign indicating number (bootcode) certainly, font sign indicating number (font code) etc.; Especially in this example, also there is erasable programmable logical device sign indicating number (EPLD code).
In EEPROM14, there is resolution usually, initial image quality, and according to the configuration information of each chip on circuit board; Especially in the present embodiment, also there be the initial of the display system of being used for from the initialization identification id information 15 of whether drawing.The initialization identification id is initial before drawing in system, has the initial value of regulation, but finishes will be updated to another value at first after drawing.
Fig. 2 is in example of the present invention, the process flow diagram of the automatic downloading method of erasable programmable logical device program.
With reference to Fig. 2 as can be known, if system draws certainly, control part 12 will remove to read the initialization identification id of EEPROM14 so, confirm initial from whether drawing (step 10) then.If initialization identification id value is an initial value, the system that so just is judged as is initial from drawing.
The result who confirms, if initialization identification id value is that initial value is (in step 10, "Yes"), control part 12 is just judged into system at first from drawing so, and read the erasable programmable logical device sign indicating number deposited (step 12), and it is recorded (step 14) on the erasable programmable logical device chip 16 from flash memory 10.
Then, control part 12 will be from erasable programmable logical device chip 16, receives erasable programmable logical device sign indicating number and whether normally obtains the assay that writes down.Here, check system preferably adopts to be checked and mode (checksum), but unnecessary this mode that is limited to.
The result of check, if not unusual (in step 16, "Yes"), control part 12 will go to upgrade the initialization identification id value (step 18) of EEPROM14 so.
On the other hand, in step 16,, turn back to step 14 so, go repeatedly later program again if the result of check has unusually.Arrive this, will finish all programs.
In this example, erasable programmable logical device sign indicating number is stored in advance at flash memory 10; This is according to the regulation control signal that generates in control part, is deposited into the chip 16 of erasable programmable logical device after reading automatically.And, unnecessary as doing in traditional operating type, in the circuit board operation, (for example to the input port of erasable programmable logical device chip, jtag port) goes up after the equipment such as personal computer that connect the outside, remove the operation process that downloads.
In addition, in this example, be that the center is illustrated with the erasable programmable logical device of programmable logic device (PLD) one example; But,, be readily appreciated that the programmable logic device (PLD) that also can similarly be applicable to other kind so if belong to the insider in this field.
More than, be that the center is illustrated with example of the present invention; But,, be appreciated that under the situation that does not break away from thought of the present invention and scope the fact that can change so if belong to the insider of this area.That is to say that the present invention owing to can change, therefore can not think and will be limited to above-mentioned example ranges in additional claim scope.
