SOPC for Real Time Multi-Video Treatments with QoS Requirements
Authors: ,
Abstract: Today, a significant number of embedded systems focus on multimedia applications with almost insatiable demand for low-cost and high performance. Generally, the majority of video applications need to execute parallel tasks with simultaneous access to the memory. One fact is that these parallel tasks have different bandwidth requirements that have to be satisfied separately when granting access to the memory. In this paper, we propose a general purpose architecture for video applications which satisfies parallel access to the memory with different bandwidth requirements. The proposed solution is based on the Multi Port Memory Controller MPMC. The management of memory accesses is assured by using the BGPQ algorithm to guarantee QoS requirements. We demonstrate the important role of this solution in multi-video applications when multiple bandwidths are required. In fact, to successful the deployment of DRAM, it is mandatory to use a flexible and scalable interface with the appropriate arbitration algorithm. The proposed architecture is implemented using the Xilinx Virtex-5 FPGA and its available resources like embedded memory, DCM’s and others. It also introduces diverse modules such as video zoom-in and out. This provides the utility of using this architecture as a universal video processing platform according to different applications requirement.
