Abstract


This paper describes an implementation based on the the SOPC technology of ultrasound instrument DSC hardware design and its software control flow . First, the system functions defined on the basis of the Nios II processor system using ultrasonic instrument DSC system design . Analysis of the the ultrasonic instrument DSC works and the mathematical model of the system structure , the use of programmable logic resources in the FPGA design DSC hardware circuit module , and one by one the description and verification . Then use the DSP development tools based SOPC design image processing module with other modules , together with the Nios Ⅱ soft -core processor with on-chip Avlaon interactive bus connection , set up a complete ultrasound instrument DSC system . In addition, the use of remaining in the FPGA programmable logic resources and IP soft core constitute embedded system interface function module , data storage , distribution, transmission as well as the man-machine interface . Nios Ⅱ core DSP for algorithm processing program architecture , system scalability and high flexibility . DSP module by the control and management of the input and output of the coordination between the Nios II processing module with module and data , parameters , image processing and optimization . Both carry out their duties, to improve the performance of the system with the greatest efficiency . Nios Ⅱ soft core embedded , is very conducive to build their own specialized embedded systems . And more and more IP and third-party support to enhance the versatility of the Nios Ⅱ system .
