RRAM developer Crossbar announced a new SPI-based AI accelerator chip, which it calls XPU. The chip targets a specific lookup phase during AI calculations and contains an RRAM memory device and a programmable coparator.
RRAM's low power and non-volatility nature fits this application and according to crossbar can achieve a 30X speed improvement over an ARM+DDR4 combination, while drawing 500X less power (the advantages of the XPU chip are increased with object length).
