This paper discusses the hardware design of Analog_Collection Subsystem for recording the dynamic process of electric power fault, analyses in detail the hardware characteristic of multi-CPU parallel run and the data exchange between CPUs with the help of the advanced technology of bidirectional RAM .

Design of multi-CPU-based UPFC control and protection system;

This design adopts multi-CPU embedded system policy and masterslave CPU hardware structure,which was developed that 89C52 microcontroller(slave CPU) played a role of AC sampling and S3C4510B(master CPU) took responsibility for calculating electric parameter,network communication and system management.

Using multi-CPU the technology to make the improvement to the isotope measuring appliance technical performance,makes it has the obvious superiority in the parallel processing and the real-time gathering data aspect and could enormously enhance the measuring appliance the.

This paper analyzes the total scheme of the HF multitone parallel signal through the sixteen tones system.

This paper introduces the concept of the HF multitone parallel signal and the technical standard of the 39 tone parallel signal, describes the principle of the 39 tone parallel signal and presents a way to realize the real time demodulation with the TMS320C30/C31.
