【文章內(nèi)容簡介】 PRS as the wireless to the system requirements, this thesis plans the terminal functions and builds the hardware platform. The terminal uses the DSP named ADSPBF532 of multimediamunications applications as the main chip, bined with SDRAM and FLASH memory. The peripherals uses video codec chip for video input and output, audio D / A chip and the amplifier for audio output, and connects the GPRS module through the serial port to GPRS wireless munications. GPRS module with builtin TCP / IP protocol stack, above the TCP protocol layer munication frontend protocol and the Management Center protocol is defined. Software design used integrated software development environment VisualDSP + + development to each , the equipment passed the three stages of testing that contains indoor testing, environmental testing, and practical applications testing, and verified the device features, the munication protocol
