A new framework for low-power modern radar System on a Chip (SoC) based on ASIX core is presented. Pivotal modules and low-power design flows are described in detail. The dynamic clock-distribution mechanism of the power management module and the influence of the chip power are both stressed. This design adopts the SMIC 0.18-μm 1P6M Salicide CMOS process, the area is 7.825 mm x 7.820 mm, there are approximately 2 million gates and the frequency is 100 MHz. The results show that the modern radar SoC passes the test on modern radar application system and meets the design requirements. The chip incurs power savings of 42.79% during the fore-end phase and 12.77% during the back-end phase. The total power is less than 350 mW for a 100-MHz operating environment.展开更多
