Recently ,the evolution of embedded systems has shown a strong trend towards application specific, single chip solutions. The ARM processor core is a leading RISC processor architecture in the embedded domain .The ARM family of processor supports a unique feature of code size reduction.IN this paper it is illustrated using an embedded platform trying to design Protocol trainer using ARM7TDMI processor. Here the kill sotware is used for ARM programming and at base station VB is used. In this we will be incorporating various day today protocols used in the embedded industry, which will be helpful in a better understanding of the subject. Successfully putting a new application of Protocol trainer on ARM7 process.
