Method for Starting Loongson 3A1000 by Using Domestic Device |
| |
Abstract: | According to the requirement of domestic product, a method of starting CPU with domestic device is
designed. The LPC bus is analyzed in detail, the memory configuration is described, and the functions of foreign LPC flash
configuration are introduced by using domestic FPGA and domestic flash. The results show that this method can replace the
function of foreign chip and realize the localization. |
