The Design of Embedded Multi-Channel Data Acquisition System

This paper analyzes the Flash Memory interface, SDRAM interface, Ethernet interface and Serial-port expansion circuit. The Embedded Multi-channel Data Acquisition System is designed by MCF5272 microprocessor. The main control system of MCF5272 includes SDRAM, Flash and BDM interface and so on. At the software design, we main introduce the compile and develop of bootload and the compiler and debugging environment of μClinux build. On this base, the general methods and points of the embedded system hardware design were summarized.
