Teach you to program DSP core in snapdragon?

Ranelle had experience only with the percent by TI. We need to learn to work with DSP processor core Snapdragon on the level of "Hello, world!". The Hexagon SDK is downloaded, a simple example of Hexagon IDE simulator run. But then, I don't understand how to run the examples on the DSP hardware. First, as I understand it, y...

Sampling of signals?

There is a signal, do I understand correctly that if the signal is limited, for sampling choose using the Kotelnikov theorem, and if not reduced. then a criterion Zheleznova? This is exactly what is called "so, you select the steps discretization in practice"? But what determines the sampling rate?

Analysing how to implement cosine modulated polyphase filter Bank for synthesizing?

Hi, dsp is a hobby for me, and probably I need to better understand the theory, nevertheless ask. There is a challenge in this synthesis filter Bank (https://github.com/FFmpeg/FFmpeg/blob/master/libav... to write the analyst. In ATRAC3plus we have a decomposition into 16 strips. I tried to adapt the code from the musepack e...

How to choose DSP for FFT transformations?

Good afternoon, friends! A SDR Board bladeRF x40 which allows you to "watch" live from width to 20 MHz.. On output it generates a large flow of IQ data that I would like to transform using the FFT on a smart DSP processor and these data to give to a PC for analysis. Help to choose the right processor. Need not very expensi...
