[0061] figure 2 A flow chart of the memory parameter configuration method provided by the first embodiment of the present invention is shown. figure 2 The method in will be executed every time the electronic device 100 is started, and the description below takes one of the start-up processes as an example. refer to figure 2 , the method includes:

[0062] Step S10 : the processor 110 of the electronic device 100 saves a set of memory parameters of each memory chip 130 negotiated by the memory controller 120 and at least one memory chip 130 to the non-volatile memory 140 .

[0063] The memory chip 130 has multiple parameters, but usually the memory parameters that can be obtained through negotiation mainly refer to memory timing parameters. The memory timing parameter is generally an integer, and each memory chip 130 corresponds to a memory timing parameter. When memory parameters are mentioned later, memory timing parameters are generally taken as an example. For other n...

[0097] Figure 4 A flow chart of the memory parameter configuration method provided by the second embodiment of the present invention is shown. refer to Figure 4 , Figure 4 The method shown and image 3 The methods shown are relatively similar in nature.

[0098] Step S20 to step S21 are similar to step S10 to step S11, and step S22 is similar to step S12, but only two situations are judged in step S22, i.e. two situations of n=1 and n>1, wherein n=1, execute step S26, when n>1, execute step S23.

[0099] Step S23 to step S25 are similar to step S13 to step S15, and step S26 is similar to step S17. There is no step corresponding to step S16 in the second embodiment, because the second embodiment does not use a set of historical memory parameters ( Figure 4 There is no n>M branch in ).

Abstract

The invention relates to the computer technical field, and provides a memory parameter configuration method and an electronic device. The memory parameter configuration method is applied to the electronic device, comprising the following steps: when the electronic device is started, saving the memory parameters of a group of each memory chip negotiated at the time; obtaining the number of starts of the equipment; obtaining a group of memory parameters of each memory chip saved each time corresponding to the starting times when the starting times are judged to be less than the starting times threshold; determining the current optimized memory parameters of each memory chip from the memory parameters of each memory chip saved each time, and determining a group of the current optimized memoryparameters of each memory chip; configuring and initializing the memory chip using a set of currently optimized memory parameters for each memory chip. The memory parameters configured by the methodhave high accuracy, which is beneficial to improving the reliability of electronic equipment, and the method can automatically adapt to the electrical characteristics of the electronic equipment itself and reduce the design cost of the electronic equipment.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a memory parameter configuration method and electronic equipment. Background technique [0002] With the rapid development of various mainstream technologies such as mobile Internet, cloud technology, and big data, embedded devices with various business functions have sprung up. In order to realize the functional requirements of these massive data processing services , large-capacity memory is often designed on the device for program running and data processing when the processor implements various functions. Correspondingly, there are higher and higher requirements for the stability of memory read and write access. Whether the memory can be accessed stably for a long time mainly depends on whether the memory timing parameters configured in the memory controller are accurate and reliable. [0003] In the prior art, there are generally two methods for obtaining memory t...
