Crossbar Delivers ReRAM AI Accelerator

Lots of companies are vying for the top spot in machine-learning (ML) acceleration that entails lots of crunching of small numbers and weights. At the end of this inference process, the system must still do the final lookup to deliver the matching information. This is often done by the host processor. Though the chore can be incorporated into an AI accelerator chip, it tends to be a bit different than processing the layers in an ML model. It's also something that works quite well as a separate device, as Crossbar's chip uses a simple SPI interface.
