Data Saving method (with axi DMA)

hello, I need some advice for saving data.

 

I want to store encoder data and the time data in DDR memory. 

 

I create a my custom IP (Axi_stream_Master) that transfer encoder data and time data sequentially to the AXI DMA.

 

However, the transfer speed of the DMA is too fast to transfer all the values ​​before the encoder value changes.

 

I want to save the data while the motor is moving and store the data in the DDR memory. 

 

I would appreciate any advice on how to proceed.
