sc_dsp_transforms .................
:Latest release: 1.0.0rc2 :Maintainer: XMOS :Description: a range of utility modules for common dsp functions
DCT Functionality:
FFT Functionality:
The purpose of this repo is to collect a series of algorithms to perform transforms on data, such as FFT, DCT, etc.
There are three modules in the repo:
module_dct_jpeg: forward quantising DCT. The process requires patches of 8x8 integer values, and in situ replace this with 8x8 transformed and quantised patches.
module_huffman_jpeg: Huffman encode for JPEG images (this may have to go in a different repo). The process requires patches of 8x8 integer values, and streams bits out over a (streaming) channel.
module_fft_simple: complex FFT (size must be a power of 2), and real FFT (two arrays of identical length that must both be a power of 2).
