| Abstract: | This article introduces the hardware system cesign and implementation of embedded PC104 Plus CPU module. The module adopts a Godson 2C CPU as the core and is compatible to the specification of PC104 PLUS bus. The key technologies such as BIOS design, system reset logic and SDRAM route topology are discussed. The CPU module based on this design has been manufactured successfully and run embedded Linux steadily. The module is also reliably used in an airborne video recorder. |
