H.264 is already introduced in several electronic gadgets like mobile phones digital video players and service providers such as online video storage and telecommunications companies. H.264/AVC comes through cooperation between the ISO/IEC MPEG and the ITU-T VCEG (Richardson 2010), this standardization was developed for the purpose of improving the(More)
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(More)
The deblocking filter is more complex than other modules in the H.264 because it is highly adaptive, applied to each boundary of all 4×4 blocks and updated three pixels in each direction. After careful study and analysis of this filter, we have concluded that its complexity lies in the data dependency and in the control module of elementary filters(More)
For a hardware implementation of any image processing algorithm, it is necessary to study the input/output of each processing module even before studying the internal architecture of these modules. And that to prepare a simulation platform, with internal and external memory, necessary to load and to prepare the input for the modules. These memories are also(More)
Motion estimation (ME) in video coding standard H.264/AVC adopts variable block size (VBSME) which provides high compression rates but requires much higher computation compared to the previous coding standards. To overcome this complexity, this paper describes a VHDL design and an implementation of VBSME. The design is based on partitioning each(More)
