ARM-Based Embedded System Platform And Portibility

This paper takes a view of methodology to survey the embedded system. The essence of embedded system is a kind of tech thinking and developing way of system design. This paper bring platform tech, witch is a best way to realise system design, into embedded system design and construct a model of platform stack for the extensive electronic engineering. Basing the model, we present an infrastructure of embedded system around the architecture platform and programing model platform.Taking the ARM7TDMI-based embedded system as an example, we show the realising process of that infrastructure. During the research, we found the loss of auto-port tools is one of the reasons of developing unefficiently. So we focuse on the portability of the embedded system's developing platform and realise an auto-porting software.
