X-ray Line Scan Security Screening Equipment, Real-time Digital Signal Processing

By designing the gain and offset circuit and providing the diagram of the circuit, this text mainly emphasizes on the realization of software and hardware, which have applied the two-point correction method. The circuit structure of DSP+CPLD, as well as, the realization of engineering applications through a two-time correction of analog and digital modules that can get a more positive effect. The UART method, which fully uses the interior resources of DSP, applied in this text has simplified the hardware circuits. In the software module, the combination of C language and DSP hardware programming in TMS320C54xx series of TI .Ltd. also contributes the transplant of programs and shortens the time for redevelopment for programs.
