SPD data automatic generation method and device, computer equipment and storage medium

Abstract

The invention relates to an SPD data automatic generation method and device, computer equipment and a storage medium. The method comprises the steps of acquiring parameter option values selected by auser; retrieving in an associated database according to the parameter option value as a retrieval condition to obtain an SPD byte bit value in a mapping relation with the parameter option value; storing the SPD byte bit value to form temporary storage data; and integrating the temporary storage data to form target SPD data. According to the invention, important parameter options and correspondingSPD byte bit values are used; Forming an associated database, Practical use, The method comprises the steps of obtaining parameter option values input by a user, searching in an association database according to the selected parameter option values to obtain SPD byte bit values corresponding to the parameter option values, storing the SPD byte bit values, collecting and integrating the SPD byte bit values to form target SPD data, achieving rapid and efficient generation of memory SPD data, and being easy to operate and high in practicability.

Description

technical field [0001] The invention relates to a method for generating SPD data in a memory, more specifically a method, a device, a computer device and a storage medium for automatically generating SPD data. Background technique [0002] With the rapid development of power electronics technology and computer technology, the computer's demand for memory is increasing. In order to improve memory performance, there is an EEPROM (Electrically Erasable Programmable Read-Only Memory) on the memory module. The IC chip is used for storing relevant information of the memory module, that is, SPD (Serial Presence Detect) data. Memory SPD data records configuration information, such as the number of P-Banks, operating voltage, number of row addresses / column addresses, bit width, various main operation timings, etc., and the mainboard north bridge chipset will automatically configure the corresponding memory work according to the SPD data information parameters Timing and control regi...

Problems solved by technology

The manual entry method is to write a value corresponding to each byte. The writing process needs to pay attention to each bit. For example, DDR3 has 256 bits, and DDR4 has 512 bits. Therefore, the manual entry method to generate SPD data is time-consuming, cumbersome, and inefficient. , and because there are too many parameters for each bit, it is easy to make mistakes; using the Eureka2 tool needs to prepare a similar SPD data file, and modify the corresponding bits on the basis of it to meet the requirements. Although this method is faster and more intuitive than manual entry , but this method needs to be based on a similar file, which is limited to a certain extent
