技术领域technical field
本发明涉及电子技术领域，尤其涉及一种机顶盒内存分配方法及装置。The invention relates to the field of electronic technology, in particular to a set-top box memory allocation method and device.
背景技术Background technique
机顶盒是一个连接电视机与外部信号源的设备，可以将压缩的数字信号转成电视内容，并在电视机上显示出来。随着数字电视的发展，越来越多的用户使用机顶盒来接收数字信号进而收看数字电视。A set-top box is a device that connects a TV with an external signal source, converts compressed digital signals into TV content, and displays them on the TV. With the development of digital TV, more and more users use set-top boxes to receive digital signals and watch digital TV.
机顶盒内部不同软件模块在执行任务时，需要从系统可用内存中分配内存给对应的软件模块以执行各自的任务。目前大多分配内存的方法是估算一个软件模块需要的内存大小的估计值，固定分配估计值大小的内存给该软件模块。在机顶盒图文处理模块开发的过程中，根据不同的需求，图文处理模块，例如UI模块，处理的图片或者文字随时可能改变，则图文处理模块需要的内存大小也会随之变化，那么固定分配内存的方法，有可能会造成分配的内存不足导致运行失败，或分配的内存有剩余可能造成内存碎片或内存泄露的问题，如果每次开发人员每修改一次图像或文字就修改一次给图文处理模块的内存的大小，将极大地影响机顶盒图文处理模块的开发效率。When performing tasks, different software modules inside the set-top box need to allocate memory from the available memory of the system to the corresponding software modules to perform their respective tasks. At present, most methods of allocating memory are to estimate the estimated value of the memory size required by a software module, and fixedly allocate the memory of the estimated size to the software module. In the development process of the graphics and text processing module of the set-top box, according to different requirements, the graphics or text processed by the graphics and text processing module, such as the UI module, may change at any time, and the memory size required by the graphics and text processing module will also change accordingly. The method of fixedly allocating memory may cause insufficient allocated memory to cause running failure, or excess allocated memory may cause memory fragmentation or memory leaks. If the developer modifies the image or text every time The memory size of the text processing module will greatly affect the development efficiency of the text processing module of the set-top box.

S101，获取图文处理模块的图文处理对象。S101. Acquire an image-text processing object of an image-text processing module.
具体的，上述图文处理模块可以是UI模块，上述图文处理对象包括图片对象和/或字符对象。步骤S101可以是机顶盒开机后触发执行的。机顶盒内存分配装置可以从机顶盒内部的存储介质中图文处理模块对应的存储位置获取图文处理对象。上述机顶盒内部的存储介质和机顶盒系统内存是两种不同概念，上述机顶盒内部的存储介质用来存储机顶盒软件模块的运行程序或数据等，如图文处理模块的图文处理对象，机顶盒关机断电后，图文处理对象仍然存在，上述机顶盒内部的存储介质可以是存储卡，硬盘等。上述机顶盒系统内存是用来存储机顶盒运行时各个软件模块，如图文处理模块，产生的数据，机顶盒关机断电后，上述运行中产生的数据被清除，上述机顶盒系统内存可以是随机存储记忆体的空间等。Specifically, the image-text processing module may be a UI module, and the image-text processing objects include image objects and/or character objects.

The storage medium inside the above-mentioned set-top box and the system memory of the set-top box are two different concepts. The storage medium inside the above-mentioned set-top box is used to store the running program or data of the software module of the set-top box, such as the image-text processing object of the image-text processing module. Afterwards, the image-text processing object still exists, and the storage medium inside the above-mentioned set-top box may be a memory card, a hard disk, and the like.

具体的，上述图文处理对象包括至少一个图文处理子对象，分别获取所述至少一个图文处理子对象中每一个图文处理子对象的占用空间大小，将所述每一个图文处理子对象的占用空间大小累加得到所述图文处理对象的占用空间大小。例如图像展示模块需要展示的图片有五张，五张图片占用空间大小分别为50KB、45KB、20KB、25KB和10KB，则图像展示模块的图文处理对象的占用空间大小为150KB。Specifically, the above-mentioned image-text processing object includes at least one image-text processing sub-object, and the occupied space of each image-text processing sub-object in the at least one image-text processing sub-object is obtained respectively, and each image-text processing sub-object The occupied space of the object is accumulated to obtain the occupied space of the image-text processing object. For example, the image display module needs to display five pictures, and the space occupied by the five pictures is 50KB, 45KB, 20KB, 25KB, and 10KB respectively, so the space occupied by the image-text processing object of the image display module is 150KB.
若所述图文处理模块的图文处理对象为图片对象，获取每一个图文处理子对象，即每一幅图片的宽度、高度、格式等属性信息，进而根据所述属性信息得到所述图文处理子对象的占用空间大小。若所述图文处理模块的图文处理对象为字符对象，获取每一个图文处理子对象，即每个字符的占用空间大小和字符对象的总个数，以使步骤S103将二者相乘得到字符对象的占用空间大小。If the image-text processing object of the image-text processing module is a picture object, obtain each image-text processing sub-object, that is, attribute information such as width, height, and format of each image, and then obtain the image according to the attribute information. The space occupied by the text processing sub-object. If the image-text processing object of the image-text processing module is a character object, obtain each image-text processing sub-object, that is, the occupied space size of each character and the total number of character objects, so that step S103 multiplies the two Get the space occupied by the character object.

具体的，从系统内存中分配所述图文处理对象的占用空间大小的内存给所述图文处理模块，以使所述图文处理模块对所述图文处理对象进行处理。例如步骤S102中得到的所述图文处理对象的大小为150KB，则从系统可用内存中为所述图文处理模块分配150KB的内存。Specifically, memory of the size occupied by the image-text processing object is allocated from the system memory to the image-text processing module, so that the image-text processing module processes the image-text processing object. For example, if the size of the image-text processing object obtained in step S102 is 150 KB, then 150 KB of memory is allocated for the image-text processing module from the available memory of the system.
通过获取图文处理模块的图文处理对象的占用空间大小，从系统可用内存中为所述图文处理模块分配占用空间大小的内存，可以实现在机顶盒图文处理模块开发过程中随着图文处理对象的改变，为图文处理模块灵活分配内存，提高了机顶盒图文处理模块的开发效率。By obtaining the size of the occupied space of the graphics and text processing object of the graphics and text processing module, and allocating the memory of the size of the occupied space for the graphics and text processing module from the available memory of the system, it can be realized that in the development process of the graphics and text processing module of the set-top box The change of the processing object is used to flexibly allocate memory for the graphics and text processing module, which improves the development efficiency of the graphics and text processing module of the set-top box.
图2是本发明另一实施例提供的一种机顶盒内存分配方法的流程示意图，如图所示，所述方法可以包括：Fig. 2 is a schematic flow chart of a set-top box memory allocation method provided by another embodiment of the present invention. As shown in the figure, the method may include:
S201，获取图文处理模块的图文处理对象。S201. Acquire an image-text processing object of an image-text processing module.
上述图文处理模块可以是UI模块，上述图文处理对象包括图片对象和/或字符对象。所述图文处理对象包括至少一个图文处理子对象，所述图文处理子对象可以是一幅图片、一个文字或一个符号等。The image-text processing module may be a UI module, and the image-text processing objects include image objects and/or character objects. The image-text processing object includes at least one image-text processing sub-object, and the image-text processing sub-object may be a picture, a text, or a symbol.
S202，分别获取所述至少一个图文处理子对象中每一个图文处理子对象的占用空间大小。S202. Obtain the occupied space of each image-text processing sub-object in the at least one image-text processing sub-object respectively.
若所述图文处理模块的图文处理对象为图片对象，获取每一个图文处理子对象，即每一幅图片的宽度、高度、格式等属性信息，进而根据所述属性信息得到所述图文处理子对象的占用空间大小。例如，一张32位颜色、1024×768像素、格式为BMP的图片占用空间大小为1024×768×32÷8＝4096KB。If the image-text processing object of the image-text processing module is a picture object, obtain each image-text processing sub-object, that is, attribute information such as width, height, and format of each image, and then obtain the image according to the attribute information. The space occupied by the text processing sub-object. For example, a picture with 32-bit color, 1024×768 pixels, and BMP format occupies a space of 1024×768×32÷8=4096KB.
若所述图文处理模块的图文处理对象为字符对象，所述字符对象可以包括文字、字母、符号或数字等，则所述图文处理子对象可以是一个文字、一个字母、一个符号或一个数字等，可以获取预先设置的一个文字、一个字母、一个符号或一个数字的占用空间大小分别为两个字节、一个字节、一个字节和一个字节，并获取所述文字的总个数、字母的总个数、符号的总个数和数字的总个数，以使步骤S203进一步获取所述图文处理对象的占用空间大小。If the image-text processing object of the image-text processing module is a character object, and the character object can include words, letters, symbols or numbers, etc., then the image-text processing sub-object can be a word, a letter, a symbol or A number, etc., you can obtain the preset space occupied by a text, a letter, a symbol or a number as two bytes, one byte, one byte and one byte respectively, and obtain the total number, the total number of letters, the total number of symbols, and the total number of numbers, so that step S203 can further obtain the occupied space of the image-text processing object.
S203，将所述每一个图文处理子对象的占用空间大小累加得到所述图文处理对象的占用空间大小。S203. Accumulate the occupied space of each graphic-text processing sub-object to obtain the occupied space of the graphic-text processing object.
具体实现中，若所述图文处理对象为图片对象，图文处理子对象可以是一幅图片，对所述图片处理子对象从零开始编号，可以是按图片生成时间先后编排，也可以随机编排，统计所述图像处理子对象的总个数，预先设置一个占用空间中间变量，上述占用空间中间变量初始值为零，获取步骤S202中得到的编号为零的图片的占用空间大小，与所述占用空间中间变量相加，得到相加后的占用空间中间变量，继续获取步骤S202中得到的编号为一的图片的占用空间大小，与所述相加后的占用空间中间变量相加，循环该过程直到编号等于所述图像处理子对象总个数的图片的占用空间大小被累加在上述占用空间中间变量后结束，将上述占用空间中间变量的值确定为所述图文处理对象的占用空间大小。In specific implementation, if the image-text processing object is a picture object, the image-text processing sub-object can be a picture, and the picture-text processing sub-objects are numbered from zero, which can be arranged according to the generation time of the pictures, or randomly Arranging, counting the total number of the image processing sub-objects, setting an intermediate variable of occupied space in advance, the initial value of the intermediate variable of occupied space is zero, and obtaining the occupied space of the picture numbered zero obtained in step S202, which is consistent with the Add the intermediate variable of the occupied space to obtain the intermediate variable of occupied space after the addition, continue to obtain the occupied space size of the picture numbered as one obtained in step S202, add the intermediate variable of occupied space after the addition, and loop This process ends after the occupied space size of the picture whose number is equal to the total number of the image processing sub-objects is accumulated in the intermediate variable of the occupied space, and the value of the intermediate variable of the occupied space is determined as the occupied space of the image-text processing object size.
若所述图文处理对象为字符对象，将步骤S202中获取的文字的总个数乘以一个文字的占用空间大小，字母的总个数乘以一个字母的占用空间大小，符号的总个数乘以一个符号的占用空间大小，数字的总个数乘以一个数字的占用空间大小，将上述乘积相加后得到所述图文处理对象的占用空间大小。If the image-text processing object is a character object, the total number of characters obtained in step S202 is multiplied by the size of the occupied space of a character, the total number of letters is multiplied by the size of the occupied space of a letter, and the total number of symbols Multiplying the space occupied by a symbol, multiplying the total number of numbers by the space occupied by a number, and adding the above products together to obtain the space occupied by the image-text processing object.
例如，步骤S201中获取的图文处理模块的图文处理对象为五张图片：Image1.png、Image2.png、Image3.png、Image4.png和Image5.png，七个字母“welcome”和一个符号“！”，步骤S202中得到五张图片占用空间大小分别为：50KB、45KB、20KB、25KB和10KB，每个字母占用空间大小为一个字节，每个符号占用空间大小为一个字节，则步骤S203可以得到上述图文处理对象的占用空间大小为50KB+45KB+20KB+25KB+10KB+7×1KB+1×1KB＝158KB。For example, the image-text processing object of the image-text processing module obtained in step S201 is five pictures: Image1.png, Image2.png, Image3.png, Image4.png and Image5.png, seven letters "welcome" and a symbol "!", the space occupied by the five pictures obtained in step S202 is respectively: 50KB, 45KB, 20KB, 25KB and 10KB, the space occupied by each letter is one byte, and the space occupied by each symbol is one byte, then In step S203, it can be obtained that the occupied space of the image-text processing object is 50KB+45KB+20KB+25KB+10KB+7*1KB+1*1KB=158KB.
S204，从系统可用内存中分配所述图文处理对象的占用空间大小的内存给所述图文处理模块。S204. Allocate a memory equal to the occupied space of the image-text processing object to the image-text processing module from the available memory of the system.

通过上述过程，在机顶盒开发的过程中，若在所述图文处理模块的图文处理对象中添加一幅图片，则直接将步骤S203中的图像处理子对象的总个数加一，并给增加的图片编号，进而可以获取所述图文处理对象的大小，并分配相应的内存给所述图文处理模块。若删除所述图文处理对象中的一幅图片，则将步骤S203中的图像处理子对象的总个数减一，并将删除图片的编号编给比删除图片的编号大一的图片，以此类推，进而获取所述图文处理对象的大小，并分配相应的内存给所述图文处理模块。若在所述图文处理模块的图文处理对象中更换一幅图片，则将更换前图片的编号编给更换后的图片，进而获取所述图片处理对象的大小，并分配相应的内存给所述图文处理模块，提高了开发效率。Through the above process, in the process of set-top box development, if a picture is added in the image-text processing object of the image-text processing module, the total number of image processing sub-objects in step S203 is directly added by one, and given The increased picture number can further obtain the size of the image-text processing object, and allocate corresponding memory to the image-text processing module. If you delete a picture in the image-text processing object, then the total number of image processing sub-objects in step S203 will be reduced by one, and the numbering of the deleted picture will be assigned to a picture that is one larger than the numbering of the deleted picture, so as to By analogy, the size of the image-text processing object is further obtained, and corresponding memory is allocated to the image-text processing module. If a picture is replaced in the picture-text processing object of the picture-text processing module, the serial number of the picture before the change is assigned to the picture after the change, and then the size of the picture-text processing object is obtained, and corresponding memory is allocated to all Described graphics and text processing module improves development efficiency.
若在所述图文处理模块的图文处理对象中更改、添加或删除文字、字母、符号或数字，则重新统计文字、字母、符号或数字各自的总个数即可，进而获取所述图片处理对象的大小，并分配相应的内存给所述图文处理模块，提高了开发效率。If you change, add or delete words, letters, symbols or numbers in the image-text processing object of the image-text processing module, it is enough to re-count the total number of words, letters, symbols or numbers, and then obtain the picture The size of the object is processed, and the corresponding memory is allocated to the image-text processing module, which improves the development efficiency.
通过获取图文处理模块的图文处理对象的占用空间大小，从系统可用内存中为所述图文处理模块分配占用空间大小的内存，可以实现在机顶盒图文处理模块开发过程中随着图文处理对象的改变，为图文处理模块灵活分配内存，提高了机顶盒图文处理模块的开发效率。By obtaining the size of the occupied space of the graphics and text processing object of the graphics and text processing module, and allocating the memory of the size of the occupied space for the graphics and text processing module from the available memory of the system, it can be realized that in the development process of the graphics and text processing module of the set-top box The change of the processing object is used to flexibly allocate memory for the graphics and text processing module, which improves the development efficiency of the graphics and text processing module of the set-top box.
