Description

Multi-gamma burning method and storage medium

Technical Field

The application relates to the technical field of gamma burning, in particular to a multi-gamma burning method and a storage medium.

Background

As the requirement for color accuracy of products is higher and higher, there is a trend of multiple gamma (gamma, the relationship between gray scale and brightness). For multi-gamma OTP (One-Time Programmable), the configuration of the gamma number for the first writing generally determines the configuration of the gamma number for the second or third subsequent writing. That is, the configuration of the gamma number is completely dependent on the configuration of the gamma number for the first time, each OTP has to be programmed according to the fixed number, and the number of writing times after the number of writing bars is reduced may not be increased.

For example, if the memory space of the OTP register can be used to write 10 gamma twice, the memory space of the OTP register can store 20 gamma at most. If 10 gamma are recorded for the first time, 10 gamma are necessarily recorded for the second time. If 5 gamma are recorded for the first time, 5 gamma must be recorded for the second time, and the third time cannot be recorded, the remaining storage space of the OTP register cannot be used, and the availability of the storage space is only 50%. If 3 gamma are recorded for the first time, the recording can be performed only twice, and the utilization rate of the storage space is only 30%. This results in a very inflexible OTP register and a low memory utilization for the OTP register if a relatively small number of gamma are used, resulting in wasted resources.

The foregoing description is provided for general background information and does not necessarily constitute prior art.

In one embodiment, the multi-gamma programming method is performed in S10: in response to dividing a writing space of the writing register into a first preset number of writing subspaces, the step of each gamma corresponding to one writing subspace includes:

Each switch enable can be accurately distinguished by a switch enable label for each firing subspace. The application does not limit the sequence of the marks of the switch enable of the burning subspace.

Referring to fig. 2, the writing space is exemplarily divided into 20 writing subspaces, i.e. 20 boxes in fig. 2. The 20 burning subspaces are arranged from small to large according to the address size, the leftmost address of the burning subspace is the smallest, and the rightmost address of the burning subspace is the largest. The switch enables of the burning subspace are numbered from small to large in digital form, i.e. from left to right in fig. 2 are EN1, EN2, … …, EN20. In another embodiment, the switch enables of the burning subspace are numbered from large to small in digital form, i.e. from left to right, are EN20, EN19, … …, EN1.

After gamma is recorded in a certain recording subspace, the state bit is converted from the first state bit to the second state bit, and the second state bit is 1.

In this embodiment, by adding the status bit, whether each writing subspace is written or not can be accurately displayed, and whether gamma is stored or not can be accurately displayed.

labeling gamma from small to large in digital form;

Illustratively, 10 gammas are acquired, numbered gamma1, gamma2 through gamma10 for the 10 gammas in digital form. The gamma marks are sorted by labels, so that the gamma marks are conveniently stored in the burning space according to a fixed preset sequence. Illustratively, gamma1 corresponds to the writing subspace of the minimum address, gamma2 corresponds to the writing subspace of the second minimum address, and so on, 10 gammas are written from gamma1 to gamm 10. In another embodiment, gamma1 corresponds to the largest address of the recording subspace, gamma2 corresponds to the second largest address of the recording subspace, and so on, the 10 gammas from gamma1 to gamm10 are recorded. In another embodiment, the writing may be performed in the order from the small mark gamma to the large mark gamma according to the small mark gamma corresponding to the small mark switch enabling or the small mark gamma corresponding to the large mark switch enabling. Optionally, the application does not limit the correspondence between the gamma labels and the address sizes in the preset sequence, and only requires that a plurality of gammas are sequentially stored in the sequence from the small label gammas to the large label gammas. With continued reference to FIG. 2, five gammas, GAM1, GAM2, GAM3, GAM4 and GAM9, are burned. And sequentially burning five gamma from left to right according to the small address burning subspace corresponding to the small mark gamma.

s21: the first quantity marking bits are configured to determine that the quantity of the first burning gamma in the burning space is a second preset quantity.

Illustratively, a first number of labeling bits are added for labeling the number of the current burning gamma.

S22: and reading the status bits of all the recording subspaces in the recording space, and taking the recording subspace which displays the first status bit and is adjacent to the recording subspace displaying the second status bit as the initial recording subspace.

Illustratively, the status bits of all the writing subspaces are read back, so that the writing subspaces storing the gamma can be confirmed, and the writing subspaces used in the first time of writing the gamma are obtained. And confirming that the last burning subspace is arranged in all the burning subspaces which are used for the first time, and performing the second burning gamma in the unused burning subspaces which are adjacent to the last burning subspace. Similarly, if the gamma is recorded for multiple times, the status bits of the recording subspace are read back to obtain the usage conditions of all the recording subspaces of the gamma recorded for the previous time.

S23: and burning a third preset quantity of gamma according to a preset sequence from the initial burning subspace.

Illustratively, the second firing of the third predetermined amount of gamma is still performed in a predetermined order, facilitating a subsequent reload of gamma. Optionally, the size of the third preset number is not limited, and the sum of the third preset number and the second preset number is smaller than the first preset number. With continued reference to fig. 2, the second firing gamma should illustratively begin from the firing subspace corresponding to the switch enable number EN 6.

In one embodiment, the multi-gamma programming method is performed in S23: the step of burning the third preset amount of gamma from the initial burning subspace according to the preset sequence comprises the following steps:

s24: in response to the firing register firing gammas multiple times, a quantity label bit is configured to determine the quantity of each firing gammas of the firing register.

For example, the writing register marks the number of the writing gammas at this time when writing gammas each time, i.e. configures a number marking bit, and writes the number marking bit together with a plurality of gammas into the writing space. The bits are marked by a number of bits stored.

In one embodiment, the multi-gamma programming method is performed in S24: in response to the programming register programming a gamma a plurality of times, the step of configuring the number of marking bits to determine the number of programming gammas of the programming register each time includes:

determining the starting and ending positions of the recorded subspaces stored after each gamma recording according to the quantity marking bits, the state bits of the recorded subspaces and a preset sequence;

and loading the corresponding gamma to the random access device according to the starting position and the ending position and the preset sequence so as to perform dimming display.

For example, since the gamma is recorded in a predetermined sequence each time, the usage of the recording subspace is confirmed by the status bits of the recording subspace, and the total number of each usage is confirmed by combining the number marking bits, so that the starting and ending positions of the gamma can be calculated forward. It can be understood that if the gamma of a certain firing needs to be reloaded, the number of the gamma of the firing is determined by reading the number marking bit of the firing, so as to determine the reloaded initial firing subspace in the firing subspace displaying the second status bit. And reading the gamma stored in the starting writing subspace according to a preset sequence until the last writing subspace which accords with the gamma number and displays the second state bit is the ending writing subspace. With continued reference to fig. 2, for example, if the gamma of the first writing is to be reloaded, the number flag bit is first read to be 5, and the status bits of the status bit acknowledge switch enable EN1 to EN5 of the writing subspace are read to be 1, then the reloaded starting writing subspace is reversely pushed according to the preset sequence, and the ending writing subspace is enabled to be EN5.

In an embodiment, the multi-gamma programming method further includes:

and in response to the gamma with the same number of times of writing of the writing register, determining the maximum number of times of writing the gamma according to the number of writing subspaces.

For example, if the writing register repeatedly writes the same number of gammas, the writing space can be used as follows: a=b=m-c, where a, b, c, M are positive integers, M is the number of all available writing subspaces, a is the number of gamma bars per writing, b is the number of writing gammas, and c is a variable remainder less than the number of gamma bars per writing. For example, if all available writing subspaces are 20 and 5 gammas are repeated for writing, 5*4 =20-0, meaning that a maximum of 4 times of writing 5 gammas can be repeated. If 6 gammas are repeated for writing, 6*3 =20-2, which means that 6 gammas can be written 3 times at maximum.

In one embodiment, the multi-gamma programming method further includes:

responding to gamma with different numbers of the multiple times of burning of the burning registers, and decomposing the number of the burning subspaces by the sum of positive integers of a preset number;

For example, if the writing registers repeatedly write gamma with different numbers, the case that the writing space is available may be expressed as a sum of the numbers of writing subspaces with any positive integer, where the number of positive integers is the number of times that can be written, and the value of the positive integer is the number of gamma bars that are written each time. For example, if all available writing subspaces are 20, 20=10+5+3+2, the positive integer number 4 represents the number of times that writing can be performed, and 10,5,3,2 represents the number of gamma bars per writing.

In the above embodiment, the multi-gamma writing method gets rid of the limitation of the original writing scheme on the fixed writing times, and realizes flexible writing.

Second embodiment

In another aspect, the present application further provides a storage medium, in particular, a storage medium storing a computer program, where the computer program, when executed by a processor, implements the steps of the multi-gamma burning method as described above.

Illustratively, the steps of the storage medium in performing the multi-gamma burning method as above include:

1. and storing the plurality of gamma in a sequencing way.

The gamma are stored in the OTP space according to a fixed sequence. For example, a total of 10 Gamma, corresponding to different modes, identifies the respective labels Gamma1, gamma2 through Gamma10. The principle of storing in the OTP register is to store according to the order of small number corresponding to small address or small number corresponding to large address. When the OTP is performed, the setting is performed according to the label sequence of the switch enabling. The corresponding gamma number with small switch enabling mark is small, and the corresponding gamma number with large switch enabling mark is large.

2. The total number of gamma used this time is marked.

And marking the total number of the gamma used at this time by using an OTP register, and burning the gamma into an OTP space.

Confirm OTP state before reload.

After the OTP space which is enabled to be opened by the switch is burnt, a mark position is started. By reading back the flag bit, the used OTP space can be obtained. All OTP spaces used for the time and all times before are obtained.

4.Reload。

Since gamma is stored in a certain order in the OTP space. And the state marking bit is confirmed, and the total number used at this time is combined. Forward, the current load gamma needs to be read from that switch enable to which switch enable ends. And the gamma obtained from the reload in the OTP space can be accurately corresponding to the gamma. That is, the N bits of the OTP status flag, which is a start bit of the reload according to a forward estimated bit of the gamma number used at this time, and the last bit of the OTP status flag is a stop bit of the reload, and the information of multiple gamma is reloaded from the OTP space into the RAM or the register sequentially. It should be noted that, if the current reload is the gamma of the last writing, the starting and ending bits need to be adaptively adjusted if the gamma of the last n times of writing is to be reloaded.

As described above, the multi-gamma burning method and the storage medium provided by the application are used for carrying out serial number sequencing and storage on the multi-gamma and marking the total number of the current burning gammas; dividing a sub-space into a burning space according to the space of each gamma and setting a switch to enable control; and the starting and ending positions of the current burning gamma are reloaded according to the total number of the state bits and the current burning gamma, so that the flexible burning of multiple gammas is realized, and the utilization rate of the burning space is improved.
