In this paper, we propose a real-time platform for the H.264 CODEC with a memory management method, in which we use a preloading mechanism in order to reduce access to external memory. The platform uses an external DDR2 memory (to record the sequence images) and an intelligent memory controller to read the external memory periodically to load another local memory by the macroblocks (of different sizes)...
A System-on-Chip Design of VLD (Variable Length Decoder) in multi-standard video decoder is proposed in this paper. Our design supports all the popular video compression standards, e.g. MPEG-1, MPEG-2, MPEG-4, H.264, AVS, RealVideo. Benefit from its low power, the design is especially suitable for wearable multimedia applications. Simulation results show that the whole design takes an area of 1.04mm2,...
The emergence of high-definition video into mainstream applications has imposed a challenge to researchers and engineers in the field: achieving optimal balance between programmability and hardware efficiency. The DM6467 System-on-Chip (SOC) from Texas Instruments provides both DSP-like design flexibility and ASIC-like performance at the same time for codec designs. In this paper, we investigate how...
External memory bandwidth is an important issue in system-on-chip (SoC) systems. Especially in high definition (HD) video coding, the bandwidth requirement of off-chip memory is critical in video processing. In recent researches, embedded compression shows high potential on off-chip memory bandwidth reduction. Works about embedded compression have been done for low power applications. However, there...
