What is the recommended Microcontroller for reading from AD7381-4 Quad-SPI like interface

Question

The AD7381-4 uses an enhanced SPI digital interface with CS, SCLK, SDI, and 4 SDO pins to be used in maximum throughput mode. 
 This SPI interface is different from the standard SPI or QSPI interfaces which most microcontrollers are compatible with 
 
 Is there a recommended microcontroller or a dedicated chip that can bridge this interface to raspberry pi (via USB for example)? 
 Can the QSPI-to-USB mode of FT4222H be used to read data from AD7381-4 in 4-wire mode? How should the schematic connections between the two chips look like? 
 Any other suggestions? 
 
 Thank you

Hi, We use FPGA to maximize speed and versatility and optimize performance. As of now, we haven't used or tested any microcontroller that has a higher capability in terms of speed. 
 I've seen some user uses the STM32 controller for the AD7381-4 but we haven't explored or tested this yet. I suggest you can check the link below and refer to github forum.
