You can easily calculate the application performance requirements given the standard performance specs for 1080p HD video. Then these top-level requirements can be translated into constraints for hardware implementation or software throughput requirements. For 1080p HD video at 60 frames per seconds(FPS), the following specs are listed as well as required throughput in terms of pixels per second is calculated:
Video Resolution = 1920 x 1080
Frame Width (pixels) = 1920
Frame Height (pixels) = 1080
Frame Rate(FPS) = 60
Pixel Depth(Bits) = 8
Color Channels(YUV) = 3
Throughput(Pixel/s) = Frame Width * Frame Height * Channels * FPS
Throughput(Pixel/s) = 1920*1080*3*60
Throughput (MB/s) = 373 MB/s
The required throughput to meet 60 FPS performance turns out to be 373 MB/s (since each pixel is 8-bits).
