Abstract(in Japanese) (See Japanese page)
Abstract(in English) We have developed a motion estimation LSI, named COMET (COmpact Motion Estimation processor for real-Time MPEG2 encoding) for real-time MPEG2 encoding. COMET contains a full pel resolution estimation processor, a half pel resolution estimation processor and an SDRAM interface. This chip searches motion vectors through a full search method in a horizontal and vertical range of -16pel to +15.5pel and through a telescopic search method for a high quality image compression. COMET is implemented by using 0.5μm-CMOS technology and contains 1.5 million transistors on an area of 12.46mmx10.62mm. COMET can perform real-time motion vector estimation at a speed of 54MHz for 720pel.x480pel.. An MPEG2 real-time encoding system with a high quality image for MP@ML can be realized using COMET and video DSP VDSP2.
