更多DSP及ARM + DSP 核间通信开发案例，预计将在2023Q4～2024Q1陆续发布，敬请期待。 其中 dsplib_fft 案例调用 Xtensa HiFi4 NatureDSP Library 中的库函数，对整型信号进行快速傅里叶变换与快速傅里叶逆变换，采样点从16递增至4096，并将耗时打印至串口终端。

The Fast Fourier Transform (FFT) is just a computationally fast way to calculate the DFT which reduces many of the redundant computations of the DFT. How these are implemented on a DSP has a ...

Technical Terms Fast Fourier Transform (FFT): An algorithm that efficiently computes the discrete Fourier transform (DFT) of a sequence, crucial for signal and image processing.

However, on closer examination, there are features of both algorithms that suggest at least a conceptual similarity. This note is written in a heuristic spirit and is intended to offer a motivation ...

This article describes how to implement a Radix-4 Fast Fourier Transform Algorithm using the StarCore SC3000 DSP. In this article we will introduce how the SC3000 architecture allows the ...

ConnX BBE16's 16-way MAC (multiply accumulator) architecture is optimized for the most demanding wireless DSP (digital signal processing) tasks, including OFDM (Orthogonal Frequency-Division ...

Implementing DSP algorithms in silicon requires careful selection of IP blocks based on their specifications in the context of the target application. Prior to IP-Explorer designers were required to ...

Eleven new pre-engineered digital signal process algorithms and tools and several new embedded DSP features have been developed for the next-generation Virtex-II architecture. The eleven new ...

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 ...
