Building a high-performance, quad-channel H.264 encoder using low-cost, low-power FPGA architecture.
Low-cost FPGAs are now making it possible to implement high- performance encoding systems on a cost-effective and low-power FPGA fabric. This enables systems with the right combination of power, performance, and price-points to be built using well understood FPGA fabric.
This article first lays out the architecture advantages of FPGAs for low-cost, yet high-performance video processing applications and then shows how these advantages translate into a real-world application in the rapidly expanding field of video surveillance systems.
Advantages of implementing video processing in low-cost FPGAs
Today's low-cost FPGAs feature a host of silicon features that enable high performance signal processing -- abundant multipliers, fast fabric performance, and large amounts of on-chip memory (see Table 1). This makes low-cost FPGAs an ideal platform to implement an emerging class of cost-sensitive, yet high quality image processing applications.
A good example is the family of Cyclone III FPGAs that are fabricated on advanced 65nm process technology and has abundant multiplier, memory, and logic resources that enable them to implement algorithmic-intensive applications such as video and image processing.
Power is an increasingly important consideration for many system designers. Built on the TSMC 65-nm low-power process technology, these FPGAs have additional silicon and software optimizations to offer an extremely low power consumption number.
