Energy-aware light-weight DMM-1 patterns decoders with efficiently storage in 3D-HEVC

One of the major problems in Depth Modeling Mode 1 (DMM-1) hardware design is the large memory area required for storing all wedgelet patterns. This work presents four energy-aware light-weight coding techniques to reduce the memory usage and power dissipation. Experimental results show that the proposed techniques are capable of reaching a compression rate of 76.9%, representing a reduction of 140 Kbits. In the DMM-1 hardware design, this compression rate results in smaller memory, fewer memory accesses and, thus a power dissipation decrease, reaching 678 mW for ST 65nm standard cells technology.
