With key features such as alpha blending, it is no surprise that many +websites in countries such as China and India also use larger high-resolution +PNG images on their sites. Increasingly 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 the decode time, Qualcomm Innovation Center has optimized +the PNG library found on many common OS platforms such as Web OS, Android, and +Chrome OS. Our team re-implemented the png_read_filter_row() routine to utilize +the DSP-like SIMD capabilities of the ARM NEON instruction set. It was then +tuned for the specific VeNum hardware unit found as part of the CPU subsystem +of the Qualcomm Snapdragon platform. + +This resulted in a range of 0-50% improvement in PNG decode times. |
