Is the USB interface to SHARC and ADAU processors the same device?

I saw this SHARC processor that includes a USBi "for SHARC" and I don't know if that's marketing or if the SHARCs require a different interface.

In contrast to this USBi for ADAU 1401

Or is it a case of backward compatibility for the SHARC USBi?
 
So far as I can tell, USBi, is an Analog Devices term for their USB to I2C/SPI interface: USBi (EVAL-ADUSB2) [Analog Devices Wiki]

The ADAU 1401 part you mention is an Analog devices Sigma DSP Audio Processor. SHARC is their name for another group of DSP processors: Processors & DSP | Analog Devices

So, it seems that ADI use their USBi model USB to I2C/SPI interface for programming various of their DSP chips. Does the above help with what you wanted to know?
