What’s The Difference Between FPGA and PC Based Video Wall Controller?

What makes FPGA remarkable? FPGAs are programmable like GPUs or CPUs but aim at parallel, low latency, high throughput problems like inference and deep neural networks.

FPGAs have a number of benefits, the most notable of which is speed. While FPGAs run at a low clock speed relative to modern CPUs, they are fundamentally concurrent, rather than running streams of sequential instructions, with data flowing optimally between these concurrent operations, resulting in a dramatic net increase in performance.

There is the potential for applications to run up to 100 times faster over the same code running on traditional CPUs. Pure Hardware FPGA based video wall controller Pure hardware video wall controller adopts FPGA(Filed programmable gate array) hardware graphic parallel processing and digital processing ( DSP) technology to construct distributed and modularized hardware architecture. Its purpose-build hardware and embedded operating system are uniquely optimized for both mission critical reliability and ultra-high-performance.

Thanks to its implementation of cutting edge, parallel processing hardware system, video wall controllers offer an astonishing 25Gbps of bandwidth per slot. Regardless of configuration requirements size, it provides fully real time DVI/HDMI VGA/SGI/ etc. frame rates because of its truly none-blocking communication architecture.  PC Based video wall controller EXCEPT Hard ware video wall controller, also have other type of video wall controller which is PC or windows based. is a computer running an operating system (e.g., Windows, Linux, Mac) in a PC or server equipped with special multiple-output graphic cards and optionally with video capture input cards.

These video wall controllers are often built on industrial-grade chassis due to the reliability requirements of control rooms and situational centers. Though this approach is typically more expensive, the advantage of a software-based video wall controller vs the hardware splitter is that it can launch applications like maps, VoIP client (to display IP cameras), SCADA clients, Digital Signage software that can directly utilize the full resolution of the video wall. That is why software-based controllers are widely used in control rooms and high-end Digital Signage.[10] The performance of the software controller depends on both the quality of graphic cards and management software. There are a number of multi-head (multiple output) graphic cards commercially available. Most of general purpose multi-output cards manufactured by AMD (Eyefinity technology), NVidia (Mosaic technology) support up to 6-12 genlocked outputs.[citation needed] General purpose cards also do not have optimizations for displaying multiple video streams from capture cards. To achieve larger number of displays or high video input performance one needs to use specialized graphic cards, video wall controllers typically support bezel correction (outside frame of monitor) to correct for any bezel with LED displays or overlap the images to blend edges with projectors.

Under the impact of COVID-19 epidemic on the lifestyles of the world's society, BRWall leadership analyzed and summarize the market opportunities of the LED industry after pandemic. Mr. Leo, CEO of BRWall claim, I hope that our colleagues and distribution partners can fully realize that LED display products are finally presented as big data With the important role of the intelligent interaction core in the fields of emergency command, smart conference, smart city, etc., firmly grasp the opportunities brought by digitalization and intelligence, and achieve greater development together with BRWall.
