SOC Techology and System-level Low-power Design

The paper introduced the technology of IP Reuse, hardware and software co-design, SOC verification, measurement and low-power design on the SOC design. SOC on the low-power design of the transient power optimization, the average power consumption optimization and the physical power sources, capacitors charge and discharge power, short-circuit power consumption, static leakage power were also analyzed. On the design of the typical SOC chip design, packaging to reduce capacitance and lower supply voltage to reduce power consumption of the technology were studied. Finally, low-power design of the power system on the system-level power designand low-power design in operation system were discussed.
