| With the development of large scale integration technology, DSP made a breakthrough in function, processing capacity and processing speed, and it is widely used in the field of data communication, image processing, speech processing and automatic control. Embedded system based on DSP is the general purpose system that embeds DSP system into the electronic system. This kind of system has all the technical characteristics of DSP system and the technical characteristic that applied target needs.The thesis studies that the design and realization of embedded measure and control system based on DSP. Seeing that most measure and control systems have certain generalities and that is the minimum system of measure and control system is almost same. As a result, it is unnecessary to design again when we want to design a complex system. We just need to reality the functions of them through increasing some circuit.The project is posed based on this target. The system uses the TMS320LF2407 of TI Company as the CPU and uses EMP7128S as the logic modules of interruption, encoding and control. The system of LCD and keys has friendly human-computer interaction and interface. At the same time, SCI, USB, D/A module and expansion slots are integrated on this system. Some commonly useful control algorithms are solidified in this system for user.This thesis states the hardware design mainly and introduces the design flow of software. Modularize design philosophy is used in the hardware design and this thesis gives the design scheme and detailed design drawing of hardware. |
