基于 FPGA的小波去噪的硬件实现
Implementation of wavelet denoising algorithm based on FPGA
摘要
Abstract
In order to solve the limitation of single resolution in optical signal processing with traditional frequency domain denoising method , a multi-resolution wavelet denoising method was put forward .The effectiveness of wavelet denoising method was verified through contrast .According to the high requirements of hardware platform in wavelet denoising method , a field-programmable gate array ( FPGA) was put forward as hardware platform .The wavelet denoising method based on distributed algorithm transforms complicated multiplication to simple parallel look -up table accumulation process.It improved the computational efficiency and completed the hardware transplantation .A storage testing system based on FPGA was designed and the hardware verification was realized .Experimental results showed that the denoising effect was well realized on FPGA .关键词
