Abstract

This paper presents an embedded multi-channel video encoder using single-chip TI DM642 DSP.Not only could it process 4-way video signals real-time

but also it is full-function

high-reliability

small-size cubage

flexible control and low-power consumption.We construct encoder hardware platform by taking full advantage of DM642 DSP

video ports of DM642 can accept multi-channel video signals at the same time

and DSP handle video data parallel with the operation of data transferring using EDMA.By analyzing the hardware architecture and resource of DM642

we presents GMB coding scheme and efficient algorithm for DSP

namely fast motion estimation algorithm by calculating the best position in sub-pixel level

and DSP-based efficient quantization algorithm etc.
