An ultrasonic telemetry and a neural stimulator are presented. The wireless charging, data transmission and neural stimulation are demonstrated in this work. A frequency-shift keying with pulse-width modulation is adopted for wireless charging and data transmission. The stimulator provides an output current of 0μA~900μA. The frequency of the current pulse is from 60Hz to 320Hz. This ultrasonic telemetry...
As the latest product of Godson processor series, the Godson-3B processor is an 8-core high-performance general-purpose processor implemented in 65nm CMOS low-power general-purpose mixed process with 7 layers of Cu metallization. Godson-3B contains 582.6M transistors (including 4MB L2-cache) within 299.8mm2 area. The number of signal pins in Godson-3B is 654. The highest frequency of Godson-3B is...
Godson-3A is a quad-core version of Godson-3 series which is a 174 mm2, 425 million transistors chip fabricated using 65 nm CMOS LP/GP process technology. It can be running at 1 GHz with less than 15 W power consumption. Large scale, high frequency, low power and tight time schedule make great challenges in the chip design. To overcome these challenges, a design methodology based on ASIC combining...
