Real-time Acquisition of Spectrum Data Based on Embedded WinCE

To overcome the problem of orderly transferring control of spectrum data of spectrum analyzer, a real time acquisition system which runs on WinCE Operating System is implemented, and it is designed on ARM＋FPGA hardware platform. The main achievements of this paper are as follows.. ARM＋WinCE communicate with the external device buffer FIFO through a virtual address mapping mechanism. What＇s more,the real time system acquires real time spectrum data buffered in FIFO according to a reasonable and efficient algo rithm, and it realizes high definition display of frequency characteristic data of the measured signal on LCD.
