libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals...

Partial Image Encryption encrypts the huffman encoded high frequency coefficients in a jpg image file. The encryption is done in-place so the project can eventually be ported to a Windows kernel filter driver. Just encrypting the high level frequency coefficients serves to blur the image, but almost in an artistic way. The image contents are fully recognizable, but the details are pixelated or blurred. The general purpose of this program would be for securing images on the disk or in the cloud...

ARM7 targeted MP3 player. Fixed point 16 bit. Purpose is to buid an MP3 player with the lowest possible cost. Works on mono files (going stereo shouldn't be very complicated). Doesn't use Helix. The huffman decoding uses a clustering based algorithm.
