Today high-end video and multimedia processing applications require huge amounts of memory. For cost reasons, the usage of conventional dynamic RAM (SDRAM) is preferred. However, SDRAM access optimization is a complex task, especially if multistream access with different QoS requirements is involved. In [8], a multi-stream DDR-SDRAM controller IP covering(More)
Digital film processing is characterized by a resolution of at least 2 K (2048 × 1536 pixels per frame at 30 bit/pixel and 24 pictures/s, data rate of 2.2 Gbit/s); higher resolutions of 4 K (8.8 Gbit/s) and even 8 K (35.2 Gbit/s) are on their way. Real-time processing at this data rate is beyond the scope of today's standard and DSP processors, and ASICs(More)
The challenges posed by complex real-time digital image processing at high resolutions cannot be met by current state-of-the-art general-purpose or DSP processors, due to the lack of processing power. On the other hand, large arrays of FPGA-based accelerators are too inefficient to cover the needs of cost sensitive professional markets. We present a new(More)

This paper presents a multi-board, multi-FPGA hard-ware/software architecture, for computation intensive, high resolution (2048x2048 pixels), real-time (24 frames per second) digital film processing. It is based on Xilinx Virtex-II Pro FPGAs, large SDRAM memories for multiple frame storage and a PCI express communication network. The architecture reaches(More)
