Abstract :
In this paper, a low power 2-D DCT architecture based on direct 2-D approach is proposed. The direct 2-D consideration reduces computational complexity. According to this algorithm, a parallel distributed arithmetic (DA) architecture at reduced supply voltage is derived. In the real circuit implementation of the chip, an adder of low power consumption is designed, as well as a power-saving ROM and a low voltage two-port SRAM with sequential access. The resultant 2-D DCT chip is realized by 0.6 μm single-poly double-metal technology. Critical path simulation indicates a maximum input rate of 133 MHz, and it consumes 138 mW at 100 MHz
