Embodiment Construction

[0038] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] Since the flash used by the screen end board in a general module TV is a flash with a spi interface, and the characteristic of the spiflash is that as long as there is data modification, the entire flash will be erased and rewritten, so in order to reduce the rewriting of flash data The number of input times, improve its service life, the invention provides a method of data storage module TV screen end plate, such as figure 1 As shown, the method includes the following steps:

[0040] S1. Divide the flash into fixed data partitions, commonly used data partitions and infrequently used...

Abstract

The invention provides a method and a system for storing data in a screen end plate of a modular television. A fixed data area, a common data area and an uncommon data area are partitioned from a flash of the screen end plate, data stored in the flash is written into a memory, the data is normally read in the memory when the screen end plate runs, and only the function of the flash data area is called and refreshed in the system according to needs, so that the frequency of rewriting the data in the flash is reduced and the flash operating burden of an MCU (Micro Controller Unit) is also reduced; the data updated frequently is alternatively rewritten in multiple areas, so that the single write-in frequency is also reduced, the service life of the flash in the screen end plate of the intelligent television is effectively prolonged and the running rate of the screen end plate system is effectively improved.

Description

technical field [0001] The present invention relates to the field of smart TVs, in particular to a method and system for storing data on the terminal board of a modular TV screen Background technique [0002] The modular TV divides the TV into the screen end board of the display part and the smart card end of the intelligent function module; the screen end board needs to save its own parameter configuration and some parameter configurations sent by the smart card end to ensure that it does not need to be reconfigured after each boot. parameter. Because the functions realized by the screen end board are relatively simple, there are few codes and data. SPI flash with a relatively small capacity is often used as a storage carrier to save hardware resources. The characteristic of spi flash is that even if only one data is written, a block needs to be rewritten, and the number of write times of spi flash blocks has a life limit, and the writing rate is also very low. Frequent ...
