Efficient memory IP design for HDTV coding applications

The memory intellectual property (IP) is a key component for video coding systems as using system on one chip design methodology. In this paper, cost-effective memory design and complex address generation are presented for high-definition television coding applications. The addressing method uses a bit-allocation approach to simplify the computational circuit and significantly improves the memory access speed. For the bit-allocation requirement, a new memory structure is designed using pseudoaddress decoding concept to reduce the I/O complexity and to shorten the access time. The memory IP integrated to practical video coding systems is also presented. The experiments show that the proposed memory IP can provide better performance than the conventional one.
