  In this paper, we introduce a low-complexity approximation for the discrete
Tchebichef transform (DTT). The proposed forward and inverse transforms are
multiplication-free and require a reduced number of additions and bit-shifting
operations. Numerical compression simulations demonstrate the efficiency of the
proposed transform for image and video coding. Furthermore, Xilinx Virtex-6
FPGA based hardware realization shows 44.9% reduction in dynamic power
consumption and 64.7% lower area when compared to the literature.
