Television and data storage method and device thereof

Abstract

The invention is applicable to the field of television and provides a data storage method, a device and a receiving terminal for the television. The method comprises the following steps of: arranging a space in a memory; dividing the space into a plurality of sectors which are respectively divided into a plurality of units; detecting if the data needs to be saved according to the time of the system setting; searching the units which do not store data in the space arranged in the memory when the data needs to be saved; and writing down the data which needs to be saved in the searched units which do not store data in sequence. The invention is divided into a plurality of sectors through the memory, divides each sector into a plurality of units and stores the data which needs to be stored in each unit in sequence; as the variables which are saved are dynamically stored in the memory, the invention avoids the process for wiping the memory once when the data is saved every time, and the memory is wiped once after the sectors of the whole memory are completely written on, thereby greatly prolonging the service life of the memory.

Description

technical field [0001] The invention belongs to the field of televisions, and in particular relates to a television and a data storage method and device thereof. Background technique [0002] At present, most TV systems rely on the internal E2PROM to store parameters such as frequency band data, volume, brightness, and the program position before the last shutdown. E2PROM is a memory that can be electrically erased and written online. It has the characteristics of small size, simple interface, reliable data storage, online rewriting, low power consumption, 1 million erasing and rewriting times, and data storage for 100 years. Therefore, it has always occupied an irreplaceable position in the storage data of TV sets. [0003] However, with the continuous development of TV technology, the complexity of the TV system is also increasing, and the 8-bit single-chip microcomputer as the main control chip of the TV has become insufficient. Therefore, the 32-bit processor began to ...

Problems solved by technology

[0010] However, because the TV system needs to save data frequently, sometimes it may need to save the information of the user changing the channel, and sometimes it may need to save the volume, and the address of these data in the SPI Flash is fixed. If you want to save a byte, you must first Erase the space of one sector, which will seriously affect the life of SPI Flash
