about c674x in dm8168

Hi,

    I want to use the dsp c674x to integrate my algorithm to deal with 1080P video.

    Theoretically, c674x is working in 1GHz and supposed 1 pixel use 1 cycle.

    Then for 1080P video ,calculating a frame would use 1920 * 1080 * 2 * (1 / (1024 * 1024 * 1024)) ≈ 0.004s = 4ms.

    Is that right?

Thanks!

Best regards!
