Blackghost 1.0 test chip: On the road towards commercializing ultra-low-Vdd SoC for Internet-of-Things
2017 IEEE SOI-3D-Subthreshold Microelectronics Technology Unified Conference (S3S)(2017)
摘要
We introduce the Blackghost 1.0 SoC developed in Qualcomm Research, which is our first test chip that paved the road towards the commercialization of the ultra-low-Vdd Blackghost product family. Through seamless integration of many low-power innovations from software, hardware, architecture and circuit, Blackghost delivers unmatched power efficiency for battery-powered Internet-of-Things. It integrates a low footprint sensor/control processor based on ARM Cortex M0, an on-die power management unit with direct battery attach capability, a computer vision classifier processor, a programmable DSP hardware accelerator and an ultra-low-power analog front end on a 3×3 mm

die in TSMC 28LP CMOS process technology. The computation can operate at near-threshold voltages (<;0.6V) at frequencies up to 50 MHz and draws only <;9 μA/MHz from the directly attached battery.
