A Design Of Portable Digital Testing Equipment Based On DSP

The software and hardware design of portable digital testing equipment based on TMS320VC5510 are presented, which is the newly efficient and low power consuming DSP of TI corporation. The system realizes the requirement of sample theorem when sampling the wide spectrum signal with an equivalent sample technology, integrates the LCD control core in CPLD and makes CPLD as LCD controller instead of specific LCD controller, and makes the colorful STN-LCD as terminal displaying facility. The system suits the development requirement of the new portable digital testing equipment with the specialities of low power consuming, high integration and good displaying interface. At last, the implement results of the system on the DSO having 200MSPS are presented.
