MPR（Multi Purpose Register，多用途寄存器）Pattern Write 实际上并不是一种校准算法，通常是读写对齐（Read/Write Centering）之前的一个预备步骤。 DDR4 DRAM 包括四个 8 比特可编程寄存器，称为 MPR，用于 DQ 比特训练（比如 Read/Write Centering）。 DDR5 SDRAM. 此training 找到正确的cycle 来设置data buffer中的Read Latency 值。 在此training mode下，controller 对data buffer MPR 寄存器预编程expected pattern ，并发出read 命令。 DRAM DCA Training PHY Read DCA Training Read Gate Training/ Strobeless Training Read Data Training Done Tx DFE Training PHY Write DCA Training Read Training Max Read Latency Training Write Training Figure 4: DDR training SERDES programming, DDR training, filter calibration, and equalization can be accomplished through hardware; for example, using Nov 30, 2021 · Intel’s 12th Generation Core processors, code-named "Alder Lake," just hit the street, and with them begins the Age of DDR5. Maximum 5 The built-in pattern lock tool is useful for adding an extra layer of security to your Android smartphone. These individual routines, such as read training, read preamble training and write level training, align DQS pins to DQ pins and center align these to a reference clock. xnhpb wegl vnskx bbovwj vcqw zbbyues den aurnub arpt fes
