Abstract

A 3D Blu-ray-compliant multimedia processor integrating video decoder, display and graphic engines is presented. To cope with the bandwidth/cost-starved Blu-ray system, this design exploits the time-sharing techniques, leading to 31.3% and 29.1% of area reduction in display and decoder parts. Moreover, a graphic and on-screen-display hardwired handshake effectively reduces the DRAM space by 40%. A smart graphic command removal eliminates the redundant memory accesses by 14%. For 3D Blu-ray playback requirements, stereo full-HD video decoding, 24Hz display, and stereoscopic graphic UI are realized under the frequency of 333MHz, 148MHz, and 333MHz, respectively. This test chip is fabricated in 40nm CMOS process with core area of 3.92mm² and power dissipation of 124.1mW.
