Abstract

Introduction We present a new lossy texture compression (TC) scheme, targeted for mobile devices, which compresses 2 4 pixel blocks into 32 bits. Compared to our POOMA TC work [Akenine-M oller and Str om 2003], peak signal to noise ratio (PSNR) is improved by 0.6 dB on average, the bit rate is reduced from 5.33 bits per pixel (bpp) to 4 bpp, and we avoid 23 blocks that are awkward for hardware implementation. Most mobile devices, such as phones and PDAs, have very limited available memory bandwidth, e.g., 16 or 32 bits/cycle. For 3D graphics applications, TC is therefore a fundamental technique for reducing bandwidth usage. Most TC schemes compress each block of pixels individually. In general it is simpler to compress larger blocks efficiently, and therefore the most common block size is 4 4 pixels compressed into 64 bits (S3TC, DXTC). If a compressed block occupies the same number of bits as the bus width (e.g., 32 bits), then pipeline stalls can be avoided [AkenineM oller and S
