A system and a method for realizing automatic diagnosis of television DDR storage

Abstract

The invention relates to the field of intelligent household appliances, discloses a system and method for realizing automatic diagnosis of DDR storage of a television, and solves the problem that thefault position and cause of the DDR cannot be accurately positioned in the prior art. The system comprises a peripheral DDR unit and a television main chip, The television main chip is connected withthe peripheral DDR unit through a physical layer interface; Wherein the television main chip comprises a fault processing unit, a storage controller and a register; The storage controller and the register are used for initializing a physical layer interface and configuring parameters of a peripheral DDR unit; The fault processing unit is composed of an address generator and a data generator and used for testing and diagnosing fault information of the peripheral DDR unit. The method is suitable for automatic diagnosis of the DDR fault of the television.

Description

technical field [0001] The invention relates to the field of smart home appliances, in particular to a system and method for realizing automatic diagnosis of TV DDR storage. Background technique [0002] With the continuous advancement of science and technology, the functions of LCD TVs are becoming more and more abundant, and increasing the operating memory and speed has become an inevitable trend. In order to meet the needs, mid-to-high-end TVs mainly use DDR3 and DDR4, and their operating speeds are basically 2133MHZ, 2400MHZ and 2666MHZ; while the operating memory is developed to 3G and 4G to meet high bandwidth requirements. [0003] In this case, although the operating memory has been increased and the speed has been increased, since the main chip SOC on the TV motherboard and the peripheral DDR module transmit data through the high-speed I / O port, in the process of diagnosis, design and maintenance The problems encountered are also more difficult. [0004] At presen...
