After merging the code from different projects, some of which use open source compilers, I can build my own project with GCC for AVR. The first project consumes 12KB ROM and 1K RAM. I believe the RAM size can be reduced after some optimization. However
The STi7100 is a single-chip MPEG decoder. This device help you to develop the HDTV-oriented projects. The STi7100 gives high performance for low-cost high-definition systems.
