MODIFYING THE SPECTRAL ENERGY CONTENT OF A DATA BUS

摘要

Techniques for reducing the spectral content of a data bus are described herein. An example of a device in accordance with the present techniques includes logic to obtain a present bit of data to be transmitted over a data bus and estimate a spectral energy contribution of the present bit at a frequency of interest. The device also includes logic to determine what effect inverting the present bit will have on a net spectral energy of the data bus at the frequency of interest when the present bit is transmitted over the data bus. The device also includes logic to invert the present bit to generate an inverted bit and transmit the inverted bit over the data bus if inverting the present bit reduces the net spectral energy of the data bus at the frequency of interest.
