A SystemC Model of a PNG Encoder, A SystemC Model of a PNG Encoder, ,

Portable Network Graphics (PNG) is the most frequently used lossless compression standard for images. Due to PNG’s widespread use, most cameras have inbuilt ASIC to perform PNG encoding on images. Most images are automatically compressed using PNG encoders and transmitted. We present here a SystemC model to get a better understanding of its working and intended structure. In this technical report, we demonstrate a parallelized SystemC model of a PNG encoder capable of achieving high quality lossless compression with small file sizes. We first discuss the original specification of the PNG encoder application and then present its SystemC model, followed by initial experimental results that demonstrate its functionality.
