- Abstract:
- The paper presents the implementation of analog data acquisition system, in particular controlling with a 6- channel ADC converter AD7656 via the FPGA Xilinx Spartan 3 series. The procedures for data sending from the ADC to the FPGA buffers, their conversion and subsequent transmission to TigerSHARC DSP are described. The digital representations of ADC analog input signals are sent to the FPGA through three lines of serial interface at the physical layer compatible with standard SPI. After processing in the FPGA they are sent to the DSP, with the participation of the lines in standard LVDS. The paper discusses the properties of related interfaces, standards, procedures and control of ADC issues as well as algorithms of FPGA configuration program and functions implemented in this system. Selected results of functional testing are shown.
