Abstract

The invention provides a DDR adaption method and circuit. The adaption circuit comprises a main chip, a resistor RL26, a pull-up resistor RL169 and a plurality of pull-down resistors connected in parallel, wherein main chip is provided with at least one ADC port; one end of the resistor RL169 is connected with voltage VCC, and the other end of the resistor RL169 is connected with one end of the resistor RL26 and one end of the pull-down resistors connected in parallel; the other end of the resistor RL26 is connected to the ADC port of the main chip; the other end of the pull-down resistors connected in parallel are grounded; and the resistance values of the pull-down resistors are set according to a required DDR capacity value. Software with different DDR configurations does not need to be distinguished, the flexibility of the software is improved, management and control of the software are more convenient, the overall working efficiency is higher, the method is more user-friendly, and the market requirements are better met.

Description

technical field [0001] The invention relates to the technical field of DDR self-adaptation, in particular to a DDR self-adaptation method and an self-adaptation circuit. Background technique [0002] Hardware products have different hardware configuration requirements for different application scenarios and different target customers. Different choices of DDR size are very common needs. The same PCBA board needs to be replaced with DDR chips of different sizes to meet the needs of different customers. DDR size requirements. [0003] For DDR configurations of different sizes, the current common practices are as follows: [0004] 1. The main chip solution supports self-adaptive software configuration of DDR size, and different DDR configurations can be realized only by replacing the corresponding DDR hardware. [0005] 2. The main chip solution does not support adaptive software configuration of DDR size. The software needs to be adapted according to the actual DDR size. A D...
