These images are -decoded by the mobile device, and typically also scaled down to fit the user's -zoom selection on the device's browser. - -In order to improve both decode and download times, Qualcomm Innovation Center -has optimized the JPEG library found on many common OS platforms such as Web -OS, Android, and Chrome OS. Our team re-implemented several routines to utilize the -DSP-like SIMD capabilities of the ARM NEON instruction set. These were then -tuned and tested on Qualcomm's Snapdragon platform which implements the VeNum -implementation of these same instructions. - -The specific areas of focus cover VeNum/NEON acceleration of Inverse Discrete -Cosine Transform (iDCT) for 8x8, 4x4, 2x2, and 1x1 block sizes and YUV to RGB -color space conversion. This resulted in a range of 18-32% improvement in JPEG -decode and downscale times for images greater than 2Mpixels. -- cgit v1.2.3
