这是前两天搭建的H7B0单片机信号采集与计算的模块,利用它的16比特的ADC采集信号,并进行频谱分析,结果显示在OLED屏幕上。计算 2048点的FFT,耗时大约为 10个毫秒左右。下面测试一下,利用 Cortex中的 CMSIS中的 DSP算法库中的FFT,看是否计算速度能够得到提高 ...
准备好和西门子EDA一起迎接芯片赋能的创新了吗? 大家好,我是杂烩君。 随着科技的发展,很多场景下单核的嵌入式处理器已经难以满足复杂的实际计算需求,如云计算、机器学习、深度学习、图像处理、虚拟现实等需要高性能计算的领域,此时需要应用一些 ...
This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor. This audio ...
Across a range of applications, the two most common functions implemented in FPGA-based high-performance signal processing are finite impulse response (FIR) filters and fast Fourier transforms (FFTs).
The Fast Fourier Transform (FFT) remains a cornerstone of digital signal processing, underpinning applications from telecommunications to medical imaging. Modern FFT processors and architectures have ...
This is a preview. Log in through your library . Abstract Apart from the fact that they are both ingenious and remarkably efficient, there would appear to be little kinship between fast Fourier ...
Sparse Fourier Transform (SFT) algorithms constitute a transformative approach to spectral analysis by leveraging the inherent sparsity of signals in the frequency domain. In contrast to the ...
Many electronics and digital products use digital signal processing (DSP)algorithms in them. Before any algorithm gets into theproduct, an optimization process is appliedto it. The optimizationprocess ...
SANTA CLARA, Calif. - February 8, 2010 - Tensilica, Inc. today introduced ConnX BBE16, its second generation baseband engine for LTE (long-term evolution) and 4G baseband SOC (system-on-chip) designs.
In the early 2000s, digital signal processors (DSP) were simple in architecture and limited in performance, but complex in programming. However, they evolved to meet of the increased performance ...
