摘要
传统的DSP处理器在进行信号处理的时候,会花费较多的成本,造成较大的系统功耗,需要应用现场可编程门阵列(FPGA)完成DSP任务。基于此,本文从FPGA的结构特点出发,分析了基于FPGA的智能仪表信号处理,FPGA能够提升复数乘法、数字滤波器以及傅里叶变换的信号处理能力,使信号处理设备具有更优异的性能,成本与系统功耗有显著的降低。
The traditional DSP processor will spend much more cost in signal processing,resulting in large system power consumption,and it needs to use field programmable gate array(FPGA)to complete the DSP task.Based on this,this article from the structural characteristics of FPGA,analyzes the intelligent instrument signal processing based on FPGA,FPGA can promote the multiplication complex,digital filter and the Fourier transform of the signal processing ability,the signal processing device has excellent performance,cost and power consumption of the system decreased significantly.
